Or, if you want one of the coolest systems about, how about replacing that nice quiet fan for a <A HREF="http://www.deltaww.com/products/dcfans/pdf/FFB12012038...." target="_new">Delta FFB1212EHE</A> kicking out 190 CFM, and 59 dB-A @ 4000 RPM.

Bloody loud, but 190 CFM is massive air flow.

Campbell...

P.S. I've got an SLK800 - might look into one of those quiet fans, good idea.

WOW THATS A POWERFUL FAN!!! For someone who doesn't care about noise, thats THE ultimate fan!!!

Of course, you could always get some sound deadening material...

Those adapters are not so great. The don't work all that well and the extra distance that they move the fan away from the socket put a lot more stress on the CPU die and the socket itself.

That heatsink weighs 505 grams. That is a lot of weight. AMD's standard is 250g for a single clip heatsink. This is based of the information on page 20 of the <i><b>AMD Thermal, Mechanical, and Chassis Cooling Design Guide</i></b>. However again that is for a single clip. The stated amount of pressure on the die is a max of 16-20lbs. So 500 grams attached to the motherboard and using a spacer would be fine. However the Thermalright SLK-800 attaches to the socket. That is a lot of weight for the socket to take. I <b>recommend</b> that you would remove the heatsink every time you transport/move the case. (LAN parties, move it to work on it, etc.)


Campbell,

I hope that you realize that that fan weighs 370 grams. ???

That with the 120mm-fan adapter will either crack/chip some part or corner of the core; or you will stress it to death. You are talking about...

505 grams + 370 grams + the adapter = over 875 grams. You are probably talking about 16-18+ lbs. of pressure. (only a guess... Find an engineering student or ME to do the stress calculation. <A HREF="http://www.design.alfred.edu/mechanics.html" target="_new">Stress Equations for solid bodies - see axial and perpendicularly loaded bodies</A> or <A HREF="http://www.xs4all.nl/~johanw/physics-hyperref.pdf" target="_new">For a really good set of Physics Formulas go here</A>.)

Add in the vibration of the fans and the initial torque of the fan at startup and you can add some more stress.

All I am saying is that that is getting dangerously close to the limit and I would not want to get anywhere near it.

At least with a screw-down method like the Swiftech or the Alpha there is stress being distributed to the motherboard.

Another thing is that a 120mm fan will not allow full concentration of the air onto the heatsink. If you use the adapter you get restricted airflow. So the total CFM will not be what you get. There will be air resistance as it is channeled from the opening 120mm^2 down to the 80mm^2 exit.

92mm fans using the grill method is best. You will not be using the 120mm dual bladed EHE fans or the triple bladed designs. But let’s be realistic here. Panasonic, Delta, Sanyo-Denki, and Papst all have good 92mm fan. In that order Panaflo to Papst is the best CFM/dBA ratio. They are all about equal but the Panasonic wins in the 92mm category.

Okay… I said way too much here.

If you would like see some more comments on weight, heatsinks, and fans read this thread.

Sorry to burst your bubble Paul...

That fan could suck in some smaller house pets but look at this one. It is <A HREF="http://www.deltaww.com/products/dcfans/pdf/GFB120120762..." target="_new">Delta's triple-bladed GFB1212VHW-F00</A>. Try 220 CFM and 59dBA.

However you would also not want to use this on a heatsink. It weighs 570 grams.

DO YOURSELF A FAVOR, if your really interested in upgrading your hsf...

A little history on my post here first...

I had a Cooler Master HHC-001 HSF w/ an 60mm to 92mm aluminum blue anodized adapter, mounted to this monstrosity was a 92mm sunon 44cfm, 32dba bb fan.

My core temps were anywhere between 46 degees celsius and 55 degrees celsius...Ofcourse I was oc'ing my amd xp2000+ to 2200+ speeds, but I expected the hsf setup to be a lot better performing.

I lapped the heatsink, used ASIII, and everything else that I could think of in terms of preparation...Needless to say I was very dissapointed in the performance, so my quest for a more qualified hsf began.

A couple of days later and a couple of degrees hotter, through all my research, I finally settled on the Alpha Pal 8045, but I did'nt stop there, being that the Alpha Pal takes an 80mm fan and my case also has two 80mm fans, I ordered four <A HREF="http://www.coolerguys.com/Merchant2/merchant.mv?Screen=..." target="_new">crystal clear</A> blue led 80mm fans 52.6 cfm, 43 dba, rheostat adj., they are buy two get one free at <A HREF="http://coolerguys.com" target="_new">http://coolerguys.com&lt;/A>

So anyway, I recieved all the aformentioned goodies and installed them. The Alpha Pal 8045 fit perfect on my Soyo Ultra Platinum board. Fans give off a nice warm blue glow too. I have the Cooler Master ATC-210(fog verdant) case.

Now my core temps average 37 degrees celsius and 42 under load...What an improvement, and now I'm running rock solid stable..could'nt do it w/ the HHC-001...

So, Alpha Pal 8045 gets a 9 out of 10 from me...I love the way they cold forged a copper core block into an aluminum base, hats off to Alpha on this one, great job guys...

Wow, that's pretty cool for an oc'd AXP2200+. The thing is, I'd like to have something quiet. Something under 28 dBA. Which is why I'm asking if an 80mm Vantec Stealth and SLK-800 HSF combo will do the trick on an AXP2000+.

Will it? Yes? No? Too weak a fan?

Would it be better to use the grill method with an AX-7 and an 120mm Vantec Stealth? Will air flow be efficient??

By the way, what's the minimum CFM an AXP2000+ needs?

Any input would be much appreciated,

THIS REVIEW IS FOR YOU BUD,

<A HREF="http://www.hardocp.com/article.html?art=MzE3" target="_new">SLK-800</A>

Check it out and let me know what you think.

As for the Vantec Stealth, I think you will do yourself injustice to settle for a fan that only puts out 27cfm. You could do better,stay with an 80mm fan, but pick something with more cfm, for example something in the range of 36dba or so...Go <A HREF="http://www.coolerguys.com/Merchant2/merchant.mv?Screen=..." target="_new">here</A> and look at the 80mm fans, it's where I got my <A HREF="http://www.coolerguys.com/Merchant2/merchant.mv?Screen=..." target="_new">crysal clears</A> w/ adj rheostat rpm (noise) control

I am running the SLK800 with a <A HREF="http://www.thermaltake.com/products/dcfan/a1357.htm" target="_new">Thermaltake SmartFan II</A> - have the temperature sensor under the CPU (the wires are thin enough to fit between the pins) on my XP1900+ running at 12 x 137.5 MHz (1650 MHz)

I runs about 3000 rpm and isn't too loud, quoted figures are 17 dB at 1300 rpm up to 48 dB at 4800 rpm, not sure how linear this graph would be though, probably about 30 - 35 dB for me

This fan is moving about 45 - 50 CFM of air (20.55 CFM at 1300rpm to 75.7 CFM at 4800rpm). Again this is a guess as don't know how linear the air flow is between these two quoted figures.

Temperatures sit about 48C and ambient temperature about 20 - 25C - always under full load as run distributed folding on it. (I have an MSI K7N420 nForce board - have heard the temperature sensor if pretty poor on these, so 48C could be a bollocks temp...)

Hope this gives you an idea of temperature / CFM for a chip pretty similar to your own and with the same heatsink. Oh, using Arctic Silver III, but since I am not that careful, might not be very well applied, too much, etc.

Campbell...

P.S. The 120mm Delta probably is a really bad idea - something spinning that fast with that much weight would cause massive stress to the 6 plasic mounting clips on the socket - only a matter of time before they broke.

P.P.S. I must admit, I spent a long time trying to figure out which heatsink to buy - I was gonna get an Alpha Pal8045, but couldn't find one in stock, then I bought the SLK800 as a couple of reviews rated it slightly better (although some rated it worse too - nothing much to choose between any of these massive heatsinks really).

September 2, 2002 7:22:09 PM

Hmm, thanks campbell. I think I may get that setup... I really only need it to be quiet overnight while I sleep. If it's loud during the day, it's fine. So my question is, if you leave your computer with no activity, will it stay at or around 17 dBA/1300 RPM?

What are the dimensions of the SLK800? It looks big, even bigger than the AX-7. Is it smaller next to the core, meaning does it taper?

<b>I have so many cookies I now have a FAT problem!</b>
September 3, 2002 5:42:39 AM

The dimensions of the SLK-800 are as follows:

L87 x W56.4 x H48 (mm) - Top, without fan
L57.5 x W56.4 x H48 (mm) - Bottom
L25 x W56.4 - Base

September 3, 2002 7:53:59 AM

Under no load, I think my CPU sits about 40C and about 2500 rpm on the fan (not sure about this, it is usually always loaded). Should be under 30 dBA, but not certain about that.

The fan also comes with a rheostat thingy (variable resistor) that allows you to manually reduce the rmp of the fan - might be worth turning it down at night if it's too loud.

Campbell...
September 3, 2002 3:18:46 PM

Thanks. I noticed some comments in the review indicating that the large size is only a problem to motherboards with very tall capacitors near the CPU socket.

Hi kdo2milger,

I'm Victor and I also using the CoolerMaster HHC-001 HSF, so..I just have a little confusing here. Is it you change the fan only but maintain use of the Heatsink? Or change to another fan that bigger than the 60mm? How is the procedues for that?

I really need all help from this..and here is my gids,

AMD Athlon XP 2100+
CoolerMaster HHC-001 heatsink fan
Gainward Geforce 4 Ti4400
Seagate 80 GB 7200rpm
Maxtor 40GB 7200rpm
256 MB pc2700 Kingmax ram
Lian li casing with 2 fans blow in, 1 back and 1 blow up

And my CPU temp is 56 Celcius and 61 when loading
MOBo temp is around 32 Celcius.

I'm really appreacited that anyone can help me on this~!

Best regards,
Victor
September 5, 2002 2:13:15 PM

Vic,

It looks like he got the Alpha PAL-8045-T (without the fan) and put an 80mm on it.

I agree... pound for pound the Alpha is still the king of cooling. No need for a monster fan to guarantee efficient cooling. I have seen it do under 60C with 100Watts of heat to disipate while <b>only using a 35CFM fan</b>. There are not many heatsinks if any that can do this kind of heat disapation.

September 6, 2002 3:57:29 AM

i do not know if it would be useful to you but here is my five cents. Most people look at cooling from the perspecrive of the fan and heat sink alone. The ambient case temp would also be an important factor, hot case will help in having a hot chip. With that in mind bring in to the case and on to the cup heat sink a fresh flow of air from outside the case. and blow the hot air out the case would keep the cpu cooler.

I discovered this by accident while buliding a pc for a friend. The heat sink was Volcano 6Cu with a 4550rpm 60 by 60 fan. The cpu temp was 49 degrees in testing. I placed a fan perpendicular to the cpu,heat sink and fan pushing about 65cfm and the temp dropped to 40 degrees C. So i think if you get a blower, fan an blow fresh air to the coler you will get some improvement. You would have to make some kind of duct out of plastic or cardboard that won't place any stress on the chip and should give an improvement in cooling.
September 6, 2002 2:03:37 PM

Okay let me get this right. You have a fan on the heatsink and then you also placed a blower on one side of the HSF combo?

If you did this how did you attach the blower? Using a bracket like the Zalman FB123?

(This advice is free... I saved 5 cents.)
I totally agree with the better flow through the case point. It is difinately worth everyone's while to try to maximize the airflow into, through, and out of thier respective cases. It is amazing whoe efficient airflow will drop temperatures.

<b>"If I melt dry ice in a bathtub, can I take a bath without getting wet?" - Steven Wright</b>
September 8, 2002 4:31:39 AM

In response to your question Bum JC I had two free five and a quarter bays free so i Placed the blower in the bays and it blew directily at the hsf combo about 10cm away from it.
I tied the ide cables into tight spiral to reduce their blockage to air flow and that was all that was requied.

To hold the fan in place two simple brackets and some self tread screws was all that was needed ot hold the fan in place.
I has designed some duct out of card board but it was not needed. I hope that helps

September 8, 2002 5:19:28 AM

Just want to ask about how can I change my 60mm to 80 mm and is it a need for this? because recently my cpu turn up so heat until 65C.
September 8, 2002 4:18:41 PM

What is your room temp? I recently picked up an Alpha 8045 with Thermaltake Smart Fan II A1345, I think. It's a great fan with manual speed control, but my cpu core was sitting around 45 - 47 celcius idle and case temp is 30C. My room temp was pretty warm also, above 70F. Will too much thermal paste on the cpu core increase the heat? I was told to put a very thin layer of thermal paste, where you can still see the words on the core.
September 9, 2002 2:30:06 AM

Victor your question leaves me with more questions?

Why is your cpu suddenly up to 65C and what was temp it running at before it went up?
Are you Over clocking?
What type of heat sink do you have?
How fast is your fan and what brand?
What type of cpu do you have?
What type of case and how many case fans?

Why all the questions? because to give an honest answer I need more information.

The easy answer to give you would be to buy a faster though not this does not mean bigger fan. As a faster fan of the same size will push more air and remove heat faster from the heat sink. Using a faster fan but of the same size will be less hassles as well such as a bracket to attach it. And some 60mm fans running faster will be as or better at moving air as 80mm slower fan. That would be my first choice.

Remember CPU's are desidned to run farily hot but I like a cool cpu as it will be less likely to fail from thermal stress. Also CPU's get really hot when their working real hard, so doing some thing cpu intensive will cause their temp to go up. So if you are into say crunching numbers for say gas flow analysis she is going to get hot.

If you are over clocking the cpu will get hot. If you are overclocking go for an all copper heatsink. Look at TOM's articles on cpu coolers that would help also.

If your case is poorly ventilated it will diminish the effectiveness of the HSF combo.

At the end faster before bigger. Bigger if cannot get faster.
And the best HSF combo you can afford if over clocking. Again look at tom's guides on heat-sink's and fans befor you decide.

I hope that helps

and good luck

i'm not sure about the rm temps, if I had to guess I would say high 70's, you see I am stationed in Germany, and the apartment I live in does not have central heating or air cond., I am lost in the metric system, if you now what I mean. Guess I need to get a simple little mercury thermometer...

Which way do you have the fan mounted, is it pushing air or pulling air? I have mine pushing air onto the hs, and yes too much as will affect temps, thin coat is best...

September 9, 2002 6:14:36 AM

Army unfortunately, going on six years now and all of it right here in GE., on the way back to the states next year, looking forward to it, homesickness finally set in...

yeah, try cleaning it and reapplying a thin coat, the Alpha Pal 8045 has a pretty smooth surface so no need for lapping on this baby.

I'm sitting @ 36 degrees celcius cpu and 31 cha right now, using Soyo Smartgardian, and Enermax's Multi Access Transfer Panel w/ the flat probe at the cpu core. I have the Cooler Master ATC-210 Aluminum case, I modded it w/ a 120mm Enermax adj fan on the side panel right over the cpu, fsb, and mem area. I got a Vantec Iceburg chipset cooler in route, should be here today or tommorrow, from newegg, so that should help me bump up my fsb some more.
My axp2000+ is oced to 2100+(1.74ghz) unlocked, and fsb @ 138, and ofcourse I increased all voltages, and set mem to most aggressive. had it up to 1.79ghz stable in all benchmarks, but could'nt play video (download video reviews from 3dman), it would just lock up (screen freeze).

Seen in another forum (amdmb) that the axp1600+ (AGOIA STEPPING) is pretty sweet for ocing and at a heelof a price ($68.00) I believe...Think I'll get one...

September 9, 2002 5:21:29 PM

Okay... that is easy to see. I thought that you had built or found a bracket that sat the fan directly next to the HSF combo. I have thought of doing something similar with the Alpha.

I could drill out two holes in the intake cover and attach fans to the side facing the front of the case and the side facing the back of the case. (or even the top and the back side.)

Basically I can force the expulsion of the air where I choose. If the top fan is expulsing air, facing down onto the HS, then I could use a couple of fans to move it through more efficiently. (One to flow towards the HS and one facing away) This way I could use cool to enter the front and funnel air towards the back of the case.

The other would be to use two, one facing the PSU and the other the back of the case. This way I could air the expulsion effect in directions I prefer.

It might not do anything but it is an idea. I was just wondering if that is what you did. But...[sarcasm on]No...You go and trash my hopes.[sarcasm off] :smile:

September 10, 2002 2:14:00 AM

i think that your idea would improve the heat sink cooling. as it would improve air flow. my point is that blowing air from outside which is cooler than case ait will improve cooling. remember that all standard heatsinks can only carry the temp to ambinent temp.

so if as you say in your message suck fresh air in and blow hot air out will improve cooling.

try and let me know how it works out.

I would be homesick too if I'm away for that long. 120mm fan on the side is a pretty good idea and it's quiet also. Maybe I'll try your idea with the 120mm fan. I never oc my cpu so I am not familiar with those terminologies. One of these days I'll get it, after I blew up a of couple CPUs and Mobos.
Good luck in the Army and we at home salute you!
September 10, 2002 6:30:43 AM

Does anyone have any personal experience with the Volcano 7+ and the Dragon Orb(socket 478)? I was looking at the thermaltake site, and it shows both coolers with the same cfm fan, and same heat dissipation as well.
Was hoping to get some first hand experience on these, or at least a decent review that shows differences.
September 10, 2002 5:02:23 PM

Hi garvinnelson,

Thanks for your concerning, first i'm not OC my pc, all the setting also the default and normal one. The temp suddenly went up because that day I open the casing and have a slightly turn on my heatsink fan, then the temp goes crazy. I'm using the cooler Master HHC-001 with totally copper base and 60x60mm fan wtih 7000rpm. I'm also using AMD XP 2100+ cpu and my casing is the Lian Li(forgot the model) and the fans for the casing is 2 front blow in, 1 blow up, 1 1 at back. I think my heat sink fan is the faster already and normally it runs at 7000++ rpm, but my cpu just run at 56C and 60C when load, but that day go to 65C when load.

Just hope that you can help me up on this..thank you very much

yes i thougt about it and actual made a flange out of plexi and card board tube and silicon adhesive to bond everything.

I did not use it though as i said blowing air from the side worked so well i did not need to use it. But any thing to bring fresh air into the case will help.

So anyway, after a week and a half of researching like mad for the ultimate quiet hsf cooling solution, this is what I finally decided on:

<A HREF="http://www.overclockers.com/articles600/" target="_new">Thermalright SLK-800</A>: THE best heatsink. Period.

<A HREF="http://www.thermaltake.com/products/dcfan/a1357.htm" target="_new">Thermaltake Smart Fan II</A>: variable fan speeds, as low as 17 dBA @ 1300 rpm

<A HREF="http://www.zalman.co.kr/images/septemberimg/fb123b.gif" target="_new">Zalman FB123</A> (x2): I took Bum_JCRules's advice and decided against the fan adapter idea. However, this <A HREF="http://www.zalman.co.kr/images/septemberimg/fb123-ffab...." target="_new">bracket</A> is an excellent way to get that extra cooling I wanted for the CPU without adding any complications to the hsf [although, it can be placed in various places to cool anything on your motherboard, which is why I bought two :)  ]

<A HREF="http://www.case-mod.com/store/images/large/120_Stealth...." target="_new">120mm Vantec Stealth</A> (x2): w00t! 53 cfm at 28 dba!

and, last but not least,
<A HREF="http://www.plycon.com/sensor.htm" target="_new">CompuNurse - Advanced</A>: a neat little gadget to monitor the temps :) 

So what do you guys think? Will this bracket idea work? Will the extra airflow from the Vantecs actually do anything? Or am I just crazy?!

Any input would be much appreciated,

At first I was kind of worried when I opened the box for the SLK-800. It's pretty damn heavy... But whatever, it's been fine for the past month. I attached the Smart Fan II to the SLK with the fan clips; that was pretty easy. And I have the Smart Fan II on Function 2 (automatic fan speed control). It was a little annoying taping the temperature monitor to the back of the cpu but once it was set, it was fine; haven't had to mess with it since. The cord slips between the pins, no problem. (I was sad to find out that the cord of the CompuNurse Advanced did not fit between the pins, oh well..)

Now comes the fun part! I screwed in a Zalman bracket into the PCI slots and then screwed in a 120mm Vantec Stealth to the bracket. The fan is hanging right above the Smart Fan II for 53 CFM of extra air flow. Muwahahaha! And then with my other bracket, I took the screw from the box and attached another 120mm Vantec Stealth to the other side of the bracket. Some nice cooling for my PCI cards :) 

And then, just for kicks, I replaced all four case fans (Antec 1040B) with 80mm Vantec Stealths!! The old fans were some POS Power Logic fans (model PL80S12M). Stats: 27 CFM, 28.2 dBA, 2500 RPM, 54 gm. As opposted to 80mm Vantec Stealth: 27 CFM, 21 dBA, 2050 RPM. Same CFM for 7.2 less dBA! (Remember, the acoustic decibels scale is not linear; it increases exponentially!)

Well, MBM5 reports my cpu temperature at about 37/38 C, although I'm not sure how the tape on the back of the cpu affects the temperature readings from the motherboard cpu sensor. Eitherway, I'm happy, as it runs pretty damn f-ing quietly!

As for now, you can take my word for it: aside from putting an 80mm Vantec Stealth on the SLK itself (at the cost of higher cpu temps), this is one of the quietest setups around that will actually keep your cpu pretty cool. Hopefully I can get my hands on a digitcal camera soon and take some pictures. :)

Quickly get your camera because I also want to take a look on your "freezer". And now I'm also looking for a better cooling setup for my AXP 2100+.

Just don't know why before I change the paste to Artic Silver 3 was in 55C to 56C when idle, after change it turns to 57C, but the temperature quite stable from 57C to 60C when load.

Any comments on that?

For good airflow in your case, without adding too much noise, which setup of case fans would u have? (ie two in bottom front, 2 rear...etc).

Ya, 2 at front bottom, 1 at upper casing and 1 at the back of the casing.

Hello,
Why are you guys not discussing the $38 dollar Zalman all copper fanned heatsink that has the fan passivelly cooling?
This is the way I am going (unless enlightened) once I can get an xp2600 for my ga-7vxp rig. Any advice would be welcomed..

How can a fan be considered a passive cooler? I mean the thing is MOVING air right? Wouldn't active cooling be more correct? If not then what exactly is this thing? i.e. how does it work?

not snapped to the heatsink.
lower rpm fan blows onto the flowered - fanned copper heatsink. Have you not ever seen this Zalman model.
The ads claim it is the best and quiet.. ($38.00)
non-attached heatsink fan, instead of passive .. Sorry..

Oh I see. I just did a search on Zalman's website. No I've never seen these before (living a rather sheltered life right now...). Thank for the info morganwill.

Are you using one of these? How well does it cool? I guess I kinda have my doubts about it. I guess I should read the reviews.
