Just installed Corsair H50 Cooling system..how do I know its working?

I have Rampage II Extreme MB with I7 930 processor (nothing special).

Looking to OC it, preferably to 3.8-4.0 ghz.

Already OC'd it with stock cooler, but I was reluctant to run any strain tests on it in fear it would fry it...So I Went out and bought Corsair H50 cpu water cooling system. (which was a real u-know-what to install, I didnt realize that the other side of my case had an opening to access the rear part of the CPU motherboard until AFTER I unscrewed, then removed everything, and installed the blackplate. lol)

Now I install cooler, and run x20 test with it @ 360 Mhz. As the test persists, it eerily eeks it's way closer and closer to 90C, going back and forth at times (when a load is breifly taken off of it) to 67C, 68C, then right back up to 90C... I dont remember exactly what it reached but it was very near TJ Max levels twoard the end.

What I'd like to know is, I thought with this great cooler I'd have temps well under control.. well under perhaps 80C on full load... Did I install it correctly? How do u know for sure if you've installed an aftermarket cooling system right (particularly this one)??

Any feedback is greatly appreciated.

You do know that the Intel recommended Tcase temperature is 67.9c, so low 70's core temps max, right?

The H50 isn't as good as the best air coolers, however, definitely sounds like it's not quite installed right and/or your OC has too much voltage.

Hi Friend, I just built my first and have the same cooler on an asrock x58 mobo core i7. I'm getting idle temps of 35/41 c and am a little concerned. Your temps sound like what I get when I run Prime95 for 8 hours. If those are your temps at stock speed or a small oc their way high. Maybe the cooler isn't installed correctly or you have to much or to little thermal paste. Check out some vids on utube you probably can find instructional vids for both these things. good luck let us know how ya do.

Your temps are too high. Either you installed it incorrectly, or the pump isn't working and you are cooling by convection. Not good.

IMO, these self contained units are nothing but trouble. Their fans are connected to the mobo, so the mobo thinks the cooling fan is running, even when the pump fails. Worse, as you are seeing yourself, evrything looks fine from the outside too, but its not cooling - and you don't know why.

Use a high quality air cooler. They aren't "cool", but many cool better than the H50, or the H70.
September 11, 2010 4:30:35 AM

i think before you go out and buy new coolers make sure the one u have is installed correctly. Cooler master is a good product. you might not have the best but your temps wouldn't be that bad with the stock cooler. like I said earlier check out utubes.

I ve already re-set it 4 times. I've purchased 3 more fans, one of which I implemented using the push/pull configuration for the radiator.. So I dunno whats up with this thing... It's idiling at mid-40's now.. Running 21x @191 = 3.99 mhz, at 1.19v. Does this sound any better or is it still high?
September 11, 2010 2:01:55 PM

40's sounds a lot better! when you say idliling to you mean it stays arounf 40's at load etc, or its 40C when CPU is doing nothing?

No, 40C when my CPU is doing nothing/normal desktop usage/web browsing, etc. That sound kinda high? I dunno what else to do!! Ive already reset this damn thing 4-5 times now... Im starting to think I got a bunk unit... =(
September 11, 2010 2:13:08 PM

If I did any stress test on it at all I know it would hit 90-100C in no time. I m beginng to care less about these stress tests and more concerned with the stability and temp rage during gameplay. As long as its stable and temps are acceptable during Mafia II, Gears of War, etc.. Im happy. No game out there puts a 100% load on any cpu, 100% of the time. So what is the test for, really?
September 11, 2010 2:23:51 PM

something does not sound right, you should not be getting temps that high.

OK so you have reseated it a few times. I wonder if you have the pump on? My guess is iether it's still not installed properly (seriously read the manual there maybe something you missed).

could be that you have used wrong bracket, or its not screw in tightly enough to the board.

you've not taken off the sticker that protects the plate that touches the chip ?

where did you plug the pump in?

-edit-

On the Corsair water cooling, it is designed to have the fan/radiator on the "OUTSIDE" of your case.
It does this to draw cooler air into the radiator.

are any of the pipes kinked?

Your fan header for the pump might be throttled. in which case the waters moving too slow

Thanka for the help jsparrow i appreciate it. I guess the throttling issue is my last troubleshooting attempt. I assre you ive installed it 100% perfect as shown. I have asus rampage ii xtreme motherbd and theres fan 3pin connectors all over the place. I have no idea which ones are throttled and which ones r not. Thry r labeled OPT_FAN 1, 2, 3 etc.. One says PWR_OPT, which i have no idea what that means. Therefore ive decided to connect it directly to my corsair hx850 psu via molex to 3 pin converter.. That way its ensured to get 100% power at all times. Wish me luck... Thanks again
September 11, 2010 5:29:36 PM

good luck. If it still does not work properly after that then I'd send it back for a replacement.

Yeah thats what im thinking. Thinking of getting top of theline air cooler rather than water type system. I dread disconnecting all this crap if it doesnt work. Uggghhhh...... Just tell me, what should my idle, just sitting there doing nothing, temp be, at about 1.2 volts?
September 11, 2010 6:22:42 PM

around 33C or so, but can vary depending on room temp. At load even with a low to medium over-clock you should get around 60C roughly. For it to be gradually getting higher and higher leads me to believe that the pumps not pushing the water round. or there is a block or kink in one of the pipes.

Well i dunno because the tubes arent that long and they are pretty stiffed, wrapped in a thick layer of plastic, so each tube leads directly to and fro the radiator with absilutely no obstruction/kink.... Writing from iphonr so exuse the spelling :-). Im hoping the molex trick will work...

you should hear the pump and ithink you can feel it if you put your finger on it. it should buzz

If you cannot complete the stress tests, you haven't completed the build. It's that simple. At best, your PC will not last long. At worst, it will burn out soon.

But you don't need to do the stress tests at this point - you already know your build isn't working and is in danger.

1) Did you peel the plastic sheet off the heat sink before attaching it?

2) Did you apply enough paste, but not so much it has become insulation?

3) When you grab the heat sink and try to "wobble" it, does it stay put?

4). Are each of the heat sink's four connectors attached firmly through the board?

5) Is the fan spinning fast enough now?

6) Can you feel the pump running, circulating water, when you touch it?

7) Can you feel warm air on the exhaust side of the radiator?

September 11, 2010 7:38:57 PM

I really what your H50 to work, cos theres nothing worse then paying hard earned cash for hardware that does not work out the box. I'd be ranting and raving by now mate. Dont suppose you live in the UK, cos I have a Kandalf water cooling case for sale.

Ok, just did the molex switch and still seeing idle temps around 45C. Did a 7 min LinX test, unfortunately I had speedfan running at the time so u cant see the temp max, but it hit 75C and stabilized there, going down, but never higher throughout the test. I also included a shot from CPU-Z so you can see cpu speeds and voltages.

And yes, I had case open and I felt tubes getting warmer as test progressed as well as hot air coming out of the fan exhausting the radiator heat... Does this bench test appear to be normal? Should I increase BLCK speeds and multiplier and try at higher GHz speed and see results? Im almost sure they'll surpass 75C.

So what do you advise sparrow?? Thanks man.. no, unfortunately I live down in south florida (miami).. but I am about to return the H50 to CompUSA where I bought it and get an expensive air cooler.

EDIT: Oh sorry, to answer ur questions is yes I put the correct amount of thermal paste, 2 yes removed plastic covering 3 yes it is FIRMLY in place, firm connection with CPU. no pipes are kinked and I do feel heat like i said.. tubes gradually become warmer as stress test progresses...
September 11, 2010 9:13:26 PM

ok then, some progress. next then check your fans, i made the mistake (for about 1 minute) with my awesome Cool Master v6gt that i'd put both fans facing iinto the chip rather then pull/push. So double check that, and make sure through speedfan that they are maxed out. 75C is hot so dont over clock, 75C is about absolute max you would wanna go.
whast your ambient temp, florida is a hot place. you got air con?

What Voltage you got into your CPU?

Ok, just ran this LinX test for approx 7 mins:



As you can see, OC'd to 3.8Ghz @ 1.25V... RealTemp shows temps reached 91C max. Ambient temp around 76F (central air conditioned).

Fans are properly positioned in push-pull configuration, heard pump spool up during test, and tubes got hot, as well as felt hot air coming thru the exhaust fan mounted on the radiator.

I've also installed the "auxillary" fan that comes with the Rampage II motherboard, which states that only use when utilzing water-cooled system. It's a small fan that mounts one of the heat sinks by the CPU housing. Went into BIOS, and ovverode the fanspeeds all to 90% load, as opposed to set to AUTO. So I think I've done all I can for now. Now its just a decision on whether or not to return the H50. Just checked the temp and its at 48C as Im writing this. If you say this is abnormal or way too high then its most definitely a problem with the cooler. What do u think??

EDIT: I noticed you advised not to OC from here, but unfortunately I already did prior to reading ur post, sorry I couldnt resist.. I thought I may have seen some better temps than 91C.
September 11, 2010 9:36:32 PM

try 3.6GHz, unless your running 2 high end graphics cards then you wont benefit from that high clock speed unless your intend to run prime95 24/7 lol.

I believe your fans are meant to pull air into the case rather then blow it out, but i could be wrong, I vaguely remember reading a review here it does make a diference.

also have you got a side panel fan pulling air in form outside over your cpu are?

Well, yesterday when I had my OC @ 4.01GHz Mafia II ran like a DREAM, definitely notecable difference between stock (2.8Ghz) and the OC'd speed, unfortunately I had the volts @ 1.4, which was VERY high.. I immediately lowered them...

I Will go down to 3.6Ghz, and lower the voltage to 1.2 or hopefully 1.18 (stable)


When I said I was feeling the hot air I meant on the INSIDE of the computer (case is open).... I have one fan positioned on the BACK of the case, on one side of the rad, sucking air in, and on the other side, blowing OUT (which is INSIDE the comp) This is the air I was referring to , which was hot during testings. I have a giant fan on the very top of the case blowing air OUT, and just installed two INTAKE 120MM fans mounted on the side... Pretty interesting setup, although Im not sure its proving to effective at this point..

So, what do you think about the temps? I ve been doing some reading on the other boards and some ppl with the i7 920 are reporting max temps of 67-70C!! some with the STOCK cooler lol... they also say anything above 85C is the danger zone, so to speak... here is the thread I was reading from http://www.tomshardware.com/forum/256908-28-what-maximu... ...

So, begs the question, should I , or should I not detach this H50 and exchange it??
September 11, 2010 10:08:43 PM

Just ran a quick 3dmark06 test at current 3.8 OC.. Here's results.. The 91C temp was from the stress test ran prior... Wasnt from the 3dmark test..



So what do you think? I dont think the H50 is doing its job properly, but, on the other hand, if the system remains stable and I can game/use comp 24/7 without issues I guess It doesnt really make a difference... However, i absolutely do not want to inflict any harm upon it by hitting these abnormal temps, but then again how often do CPU loads reach 100%? Not very often, and if they do, they tend to drop quickly.

Will a idle 47C damage anything in the long-run ? Thats probably my main concern.
September 11, 2010 10:42:19 PM

"peaking of the radiator. Corsair need the H50 installed with the airflow effectively backwards. What is the standard exhaust port becomes the intake drawing cool air across the rad. "

so to confirm your pushing air out of your system at the back.... YOU SHOULD BE drawing air in from the back of the case and pushing into your case? COS THATS WHAT IT SAYS IN THE INSTRUCTIONS!!!! DO IT! I know it sounds crazy, but thats how they designed it.

and use fans of the same type and speed, cos 2 different fans cause 'dirty' air and the flow gets all fucked up

-i hope this is all it is, and that if you reverse fans we fix the fault!!!! :o ) _
September 11, 2010 10:49:57 PM

http://www.legitreviews.com/article/1025/6/

this is roughly what temps you should expect

-edit- u got your fans like this pic?

so i guess if you have a front panel fan that will need to be outtake rather then intake, the side can still be intake and top still out..

Yes, the fans are EXACTLY like that... Like a sandwich, one attached to case is is sucking air in and fan on other side is blowing hot air OUT.. so the airflow is effectively traveling in the same direction through the whole system...

But yeah its exactly like that and same two ULTRA fans 120mm being used... The temps that are listed in the article u linked are SOMEWHAT similar to mine, but mine are obviously about 5-10C higher in some tests.. I wonder why? I noticed that the tubes are position upwards and mine are below, but ive read that makes no difference..

What the article doesnt say is how LONG of a cpu load did those temp listed result? I wish they speicified that, u know, like after 5 mins? 10 mins? etc....

Ive also done some research on compusa.com and it doesnt look like they have anything that would yeild better results.. maybee ill just exchange it for another one, maybe i just got a bad unit.. I just dont know..
September 11, 2010 11:42:32 PM

well going from what i know from water cooling i've done and air cooling aswell, i'd say you should get a steady +/- 5C after about 10 miuntes on prime95. send it back mate, get some nice air cooling instead if it will fit. i use this:- http://www.hardwarecanucks.com/forum/hardware-canucks-r...

I think before you start worrying about over-clocking you need to get the thing running below 40c and stable. If you getting that its getting better.

The thermal paste can be a real bitch. NO more than the size of a pea. And when you squeeze it out have the tip right against the cpu. You dont want any air bubbles to form in there. Some say to much don't matter. I think thats bs. the heat gathers in the excess with no where to go and thats how your temps go high.

Did you utube your cooler installation? Thats what i did for mine just to make sure it was correctly installed.

if your getting a steady 35/40 and u run prime95 it will go to 65/70 and thats OK.
Prime really maxes out the cpu and memory. Go to weki-pedia and read the article about it.
Most of all take your time and be sure of what yer gonna do. don't be in a big rush to oc to 5.0. get the thing running stable first.

40c sounds good. keep in touch.
September 12, 2010 11:05:41 AM

a peas big!, I used an amount the same size as a grain of rice or maybe a tiny bit more. its only there to fill the micro gaps in the metal i think.

-edit-

"Thermally conductive paste improves the efficiency of a heatsink by filling air gaps that occur when the irregular surface of a heat generating component is pressed against the irregular surface of a heatsink, air being approximately 8000 times less efficient at conducting heat (see thermal conductivity) than, for example, aluminum, a common heatsink material.[5] Surface imperfections inherently arise from limitations in manufacturing technology and range in size from visible and tactile flaws such as machining marks or casting irregularities to sub-microscopic ones not visible to the naked eye."

You say your beginning to worry less about stress test and more about stability? Thats exactly what the stress tests test. Go to wiki-pedia and read the article about prime95.

Your missing my point, Gerry. Lets say for instance I do a 4GHz OC. After an 30 mins to an hour of frying it with LinX, temps stablilize around 90, however POSSIBLY could reach higher temps if one were to leave it sit for longer testing.

To benchers, that temp is completely unacceptable. Nevertheless, in a "real world" gaming scenario (lets say 1 hr per day) temps of which do not exceed 75C at any one time during gameplay.

Is the system stable to run 10 hrs. at 100% load, probably not.
Can u enjoy ur games without worrying about it crashing, over heating, etc., probably.

But yes I realize stress tests are for stability. Im talking about how far do you take it..

^75C is still "too hot" for the CPU according to Intel specs, but if you're ok with it... then that's fine.

IMO, LinX isn't needed as a long term burn test. I like to run it (I use Intel Burn Test, actually) using 4gigs RAM for 15 passes. If it's stable, it's fine. Prime95 usually has lower temps but also needs to be ran for longer. At least 4 hours Small FFT gives a good indication of stability.

Not too long ago I changed my base clock from 175 to 177. Running 10 passes of IBT passed at 2.5gigs RAM so I thought it was fine. Then one day I experienced several crashes while gaming. Thought that was odd (worked fine for the last several days) but decided to run some stress tests. P95 had an error after about 1.5hrs, so I upped my VTT/IMC a pinch and reran with IBT at 4 gigs RAM usage and it showed an error after about 6 passes (more RAM is a more accurate stability test, if using less RAM you'll want to do 20-25 passes I'd say). Eventually with a pinch more Vcore and VTT it passed no problems and since then I haven't had any crashes. So IMO stability is very important.

Yeah, I understand wolf... totally... Im just about to take the case apart and take out the H50, box it up, and take back to compusa and exchange for another one. Once installed, that'll at least elimiate one more troubleshooting problem..

Quick question, aparently the H50 mount comes with sin susi paste or whatever its called, considered suprerior to even AS5.... What do u think, wipe CPU block clean then apply, or remove stock paste and apply my own Ultra goop I got (meant to cover entire cPU block with very thin layer via a nail polish type applicator)?

Or perhaps ill try both in sequential order and monitor temps, if stock TIM works then Im good, if not I always have my own to try..

man I hope this works..

Well maybe someone else can reply as to which TIM might be better. As far as I know, there's been a few improvements over AS5 but I've never heard of the two you're mentioning.

As for application, I personally would advise against the pre-spreading. I found after multiple applications I got the best result with two very thin lines of TIM (like having 3 or 4 uncooked rice grains in a row) running parrallel to eachother and to the cores of the CPU, approx 1/4" appart or a bit less than that (and the end before the edge, otherwise it may flow over). Then just apply even pressure, and it will automatically fill any large gaps and get squished out of areas that are well-mated together.

I saw somewhere on the 'net a guy with an H50 mounted the block upside down.... doing htat right now, sort of a last desperation attempt, to see if it yeilds any better results.... just about to hook it up for a trial run

So, bottom line is, 50C idle (cpu at 0 load) even at a 4.0 OC, is till WAY too high for the H50, right?

Your missing my point, Gerry. Lets say for instance I do a 4GHz OC. After an 30 mins to an hour of frying it with LinX, temps stablilize around 90, however POSSIBLY could reach higher temps if one were to leave it sit for longer testing.

To benchers, that temp is completely unacceptable. Nevertheless, in a "real world" gaming scenario (lets say 1 hr per day) temps of which do not exceed 75C at any one time during gameplay.

Is the system stable to run 10 hrs. at 100% load, probably not.
Can u enjoy ur games without worrying about it crashing, over heating, etc., probably.

But yes I realize stress tests are for stability. Im talking about how far do you take it..



i was just replying to your statement, " I m beginng to care less about these stress tests and more concerned with the stability and temp rage during gameplay". Your temps at 90c are way high. Did you check out any videos on you tube to make sure its installed correctly? NCIS or NCIX on the tube has a lot of good video how to stuff. good luck bro. I feel your pain its very frustrating but be patient and read alot yoy will figure it out.

Guys:

Have some good news... just came back from retailer, returned H50 for a brand new one... got it home, installed it right away.. fired up the comp, and was very pleased with a quick LinX run, OC'd at 4Ghz @ 1.283v... Ill show a comparison of BEFORE and AFTER..

Here's the latest run with new H50:



Now yes I know, 82C is a bit high, but remember Im at 4 GHz (21x 191) , and this is compared to THIS (old H50):



If you'll notice in that test I couldnt even complete it, as temps reached to 94C before I stopped it around 3:00... Notice the same exact CPU-Z specs between the two..

I have HT ON BTW, and for some reason in my CPU Config BIOS menu Turbo mode Enable/Disable has disappeared for some reason, it does that on occasion, sometimes I see it , someitmes I dont.. It's usually right above Intel SpeedStep(TM) option... Any idea what thats all about?

Anyway, currently idling at about 45C, not exactly overjoyed about that, but compared to the old system idling at 50-51C, it's a welcomed improvement..

Here's a Core Temp pic I've just taken this second of the current temps of my cores with the new H50 installed..



So, I guess Im pleased with the latest results, I'd like to do a bit more testing with prime95, espcially a longer-duration test to see what my max temps reach.. Low-80's with a 4GHz Oc'd id say Id be happy.. what do u guys think??? thanks for all urhelp BTW =) U think the old unit was a bit defective??

Maybe tonight you can get a good nights sleep. Good job, much better

Definitely better, but I'd keep working on that OC to try and bring voltages down and hopefully temps. I understand that hyperthreading is going to push the voltage and temps up, and maybe your ambient is higher too, but at 4ghz I was only hitting around 72C on my i5 750 (200x20) and that's with a single fan air cooler (Zalman CNPS10X Extreme). My ambient is usually around 20-24C.

I've found Turbo option dissapears if I take EIST off auto. With 21x you can probably still force Turbo on by enabling CStates and EIST but that'll need more voltage and higher temps.

I'm just curious, what do you mostly use this PC for? Because, and this is just my own feelings, I find a lower OC using Turbo and the power saving features to be far more sustainable. 4ghz on 8 logical cores is overkill if we're talking gaming and day to day stuff, only for a hardcore amount of video encoding or file compression would I consider pushing it that hard all the time. Like my sig shows, I'm currently at 177 base clock with turbo on, so it reaches 4.25ghz at single thread stuff... max temps are under 70. 1.36V LLC off (so load voltage is less, which also brough down temps by 3C compared to LLC on with less voltage). The RAM is also nicely OCed at this base clock, as I have 1600mhz CL8 RAM running at 1416mhz CL7 which required a slight voltage boost to be stable (lower speed isn't slower if the latency is lower too)

But anyway, that's just my opinion. If you're happy now, well congratulations :D
