Id like to move as much air ass possible. I'm wondering which 120mm fan does this best? I have thermaltakes right now, they max at 2800 RPM's. I've seen a couple 3100 RPM fans on the market, I'm wondering if there is anything higher?

better get two of em that way you can really simulate dual jets...

Why do you want to move so much air in any case? just outta curiosity

I overclocked a ThermalTake 120 to 11,380RPM before it blew a blade.

How about this?

220.01 CFM @ 4600 RPM


yeah, what they said. i'm currently using a couple 200+ cfm fans, you dont necessarily want high RPMs you want HIGH CFM.

and of course you're going to trade off. i have 6 HIGH cfm 120 mm fans including 2 silverstone fans and 4 comair fans, the comairs are ~220 cfm.

BUT, they are on a file server that sits in the computer room that few people ever have need to go in. it would be impossible to have those on my main machine, just too damn loud. but they push a hell of a lot of air and if the computers are in their own room then it's great.

i'm running 6 200+ CFM 120mm fans in one of my computers.

it's a 12u rackmount case that sits in my computer room (currently housing 3 servers) and is designed for massive storage. it currently holds 2.5 terabytes but it's expandable to over 10 using 500 gig drives. if i switch to 1 terabyte drives in the future the thing could go over 20 terabytes with the capability to hold 26 total hard drives.

so... yeah... i want to keep that stuff cool, but i'm not going to be in the same room with the beast ;)  that's one application for the high flow fans, but generally you dont want them on a main use computer. unless you like shouting and wear headphones a lot.

Thanks :lol: 
May 4, 2007 6:16:12 AM

Thank you for the link I just ordered two.

This is a regular ATX case, however, I am installing one on my Scythe ninja plus CPU heatsink and the other is the exhaust fan.

Sound is not a problem for me, I love loud pc fans.

Your signature supports this previously established maturity.

Although the thought of Cheeze with ANY sort of [aforementioned object] near her causes my eyebrows to rise a bit.

Overclocked? I would be interested in trying this for my front 120mm Thermaltake fan. I'd go to 4600 RPMS with it and see how long it lasts.

How do I go about trying this?
May 4, 2007 6:22:51 AM

Remember, if you want to overclock your fan to get higher RPMs, you will need to cool it with a fan so it doesn't overheat. I suggest a 140mm fan cooling your overclocked 120mm to do the trick.
Cheerio.

May 4, 2007 8:30:56 AM

Nah, even witha 140mm fan the 120mm one would die before it got to 10,000 RPM. You need one of these if you want the fan to last past 10 minutes at 11,380.
May 4, 2007 1:58:39 PM

I was joking, but nice link.

May 4, 2007 2:14:22 PM

Really? I had no idea! The fan on fan cooling sounds perfectly logical. :p

I also have a scythe ninja and Im telling you right now that the extra air is going to do just about ZERO for reducing your CPU temp.

I broke my HS fan (49 or so cfm) and switched to a temporary low rpm fan(35 or so cfm) I ordered a Minebea 73cfm replacement as well as another 46CFM scythe fan and the difference from the 30cfm fan to the 70cfm fan was about 2-3C. And that could have just been the difference in the ambient room temp. The Ninja takes very little air to do it job. My prediction for replacing the stock fan with a 200cfm fan is that you'll get 2C drop in temp and a hell of alot of noise. The exhaust fan switch will probably do more for your CPU temp then putting one on the HS.

Im not sure if you realize what 60dBA sounds like. Going from 20dBA to 23dBA is not a 15% increase. Its a 100% increase in sound intensity. Twice as loud, and 20dBA to 26dBA is 4x as loud!!! By the time you increase from your SILENT 18dBA stok fan to a 60dBA leaf blower its gonna be like REALLY LOUD!!!!!

Im trying to think of something that runs about 60dBA. Maybe a relatevly quiet generator, a loud conversation, an old sewing machine...that wat 60dBA is going to sound like and you want to put 2 of them in your desktop??? hehe...you better get a fan controller!

Of course not. It only lasted 105 milliseconds at 11,380 rpms, which closely matches 5-blade fan resonance behavior and the proportionality law relating the square of the lifetime before self-destruction and angular velocity. I'd done the math in advance so it's not like it was a big surprise but it was still a fun experiment.
May 5, 2007 5:39:52 AM

The broken, flying blade probably struck the cat that was walking by. Didn't know what hit her :cry:

I already upgraded from the stock 120mm fan that comes with the scythe, which I believe is 1500rpm. I moved to a 2800 rpm thermaltake, and the temps drops to 63* idle on my 3.15ghz oc'd e4300 with a 1.4vcore. After running prime95 torture test four hours it never goes above 108*'s which is pretty good in my opinion.

With the stock fan I was well over 120*'s, and idle was 77* or so.

The computer is in a cabinet that butts up against an opening into a big storage. I can barely hear these fans until I open it up.
May 5, 2007 1:30:33 PM

Look for Delta fans. They are obscenely loud but they get the job done.
May 5, 2007 3:18:25 PM

I just tested the cabinet I put a mini vacuum in there (its SUPER loud). I could hear it but it wasn't very loud. I almost always have my AC conditioner on (which it wasnt this morning when i tested) but when thats on, it drowns out most everything.

Any thanks for info, I already ordered two of the Delta 120x38mm TFB1212GHE Extreme High Speed fans.

I'll post some videos with the case side off/on and then with everything full blast where it will be permanently housed.
May 5, 2007 3:20:33 PM

Good luck man, those fans are EASILY louder than your average vacum.
May 5, 2007 4:17:00 PM

Well these are 50% louder than the ones I have now, and the mini shop vac is a heck of a lot louder than that I'm positive.

I do have a problem already, though. Like a dummy I didn't realize the thermal take 120mm fans I have on there now are 25mm thick, and the Deltas I'm getting are 38mm.

:x

I'll figure out a way to mount them without the original fan retainers. Maybe some stainless wire will work if I do it right. I'll post pic anyway and temp specs when they arrive and a video so you can hear the monster lol.

105 milliseconds ehh??? How did you measure that? phht whats your equasion? How are you calculating instantaneous angular velocity?
May 5, 2007 11:07:37 PM

I declare shenanagins on this guy!
May 5, 2007 11:30:53 PM

How about this one.

Now just cut a rectangular hole on the side panel of the case and secure the two together. This will cool all your pc components and cleans dust at the same time.
May 5, 2007 11:46:27 PM

WTF mate?
May 6, 2007 12:18:30 PM

Or you could just suck it up and water cool...
May 6, 2007 4:01:41 PM

But water cooling is the shizit. Your not extreme unless your water cool and/or lap your processor.

Oh you know what might also be loud if you are into PC Db Drag racing :lol: 

get a bunch of floppy drives and put them into RAID. I mean one floppy drive makes a LOT of racket, imagine 10 :) 

A jet place taking off from 10meters is 90dba. I wonder how loud a CM Stacker 830 w/ 7 of those 60dba fans would be ??


VROOOM!!!!

My house has central air conditioning, when its one the vac itself in the basement makes a $hitload of noise, from 2ft away must be 70-80dba. Got to hook a bunch of those up ;) 
May 6, 2007 11:34:41 PM

I don't like water cooling, I've had two bad experiences one ruined my out of warranty mobo the other time killed my 7900gt. Both times the rubber hose(s) started leaking. I was poor at the time and I didn't have a way to replace the board for over 2 weeks which sucks when you game as much as me. And I had to wait almost a month to get a return on my RMA'd video card.

Not saying water cooling is bad, it just takes research quality hoses/equipment and more maintenance then I'm able to put into it.

jesus, why does everyone assume that storage is for porn? perhaps because THAT is what THEY would store on it?!?! exactly.

all my dvd's are ripped as well as many tv show compilations (sorry, no porn, i've been on the internet far too long and i've seen it all, nothing i'd like to keep around) i can sit down on the couch (with the girlfriend) and we can watch anything with 3 mouse clicks, lots of snuggle time ;) 
May 8, 2007 7:59:03 PM

Just get a 4000cfm blower:
http://www.thetoolwarehouse.net/shop/BB-PB4000.html

You coudl seal it up, and connect it to the intake of your PC and the air would be forced out the exhaust and PSU vents. HAHA... i mean come on now, I have don't turn my 88CFM fans up that high on my fan control because there is a point where the heatsinks do not heat up fast enough for the fans to cool them off. It take some time for heat to transfer. But then again the only way you could cool it better is to chill the heatsinks or block and force the temprature to cool going in to the cores. Kinda like the phase change coolers.

60-80cfm is sorta getting on that edge where anything more would be a waste in most cases. although compact server racks and such would benefit from more airflow. A regular PC case with a big fat cooler would not.
May 8, 2007 8:34:21 PM

Yeah! My warehouse!

@Valis
I envy your HTPC setup. Once I get out of college and get my own place I'm building a PC with tons of storage to hold my DVDs and connect to a projector.

The thing that really makes me laugh here is that... there's a decent chance that that Clue69Less really has done something similar to this xD

So... if you wanna overclock a fan... increase the voltage ;) 

Now if you'll excuse me I have to get back to OCing my hard drives.
May 8, 2007 10:57:05 PM

Just so you know it there's a limit on how much air you can force through a heatsink or radiator (SP?), after that all you get is more noice.

Not the fastest but great at moving air:

Silverstone FM121: 110CFM, 120x120x25mm, 17dbA, 800-2400RPM, 4 pin, plastic. Includes Fan speed controller.

SilenX Ixtrema Pro: 72CFM, 120x120x25mm, 14dbA, 1400RPM, 3 pin and 4 pin, aluminum.
May 9, 2007 1:40:37 AM

Maybe this would be more suitable...


May 9, 2007 2:52:37 AM

i believe dicing machine probably has the fastest rpm. if i remember correct, the speed was about 60~100K rpm back to 10years ago.
wondered how fast they are now. :roll:

That's one solution. Creatively disturbing the space-time continuum is my favorite method for phase-locked fan/HD combos. Another is playing AC/DC records in reverse at 78rpm with the 7.1 output run through Mesa 4x12 cabs pumping an old Infinity sub servo epoxied to an inverted whammy bar connected to your power supply flux capacitors.

But I'm not going to bug you about that, if you're the ceo of a company, I find it legit to have tons of storage


and of course there's that, it stores Virtual Machines (easier to test software on multiple os's), ghost images of hard drives i dont want to lose, software, all my website information, software information, and programming.
