OCCT Linepack test i7920 w. H50

post #1 of 20
Thread Starter 
If you are testing for the highest temps your cpu will see under load, running the occt linepack test , how long should it actually take to see peak temperatures? I know this vaguely depends on your cooler but assuming my hardware is working properly how long would it actually take?

You can run it for like 30 minutes.. after that it might increase 1-2 degrees occasionally, but for me after 30min the max was pretty much stable.

hmm apparently my cpu doesnt have proper cooling, because at 1.3v vcore 3.6ghz it reached 95C underload during a 30 minute test.

Shouldnt it be more in the 75C range?


Ambient temperature in the room is around 65f. What would cause my cpu to get that hot?

I have a Coolmaster HAF 932

http://www.coolermaster-usa.com/prod...roduct_id=2810



The front fan is an intake, the side and top fans are exhaust. The H50 cooler i have the radiator fan in the back is set to exhaust air out the back of the case. This is an ok airflow setup. Would the problem then be with the cooling block on the cpu? I Mean even that occt program said "cpu too hot." lol.


Are there any programs you can use to graph and monitor cpu temps over time when you are playing games? I was thinking about how hot it would actually be getting when im playing black ops or something.

Vcore Makes a big deal with chips like ours. You might be able to drop your Vcore by raising your Vtt (that's iffy with i7 8xx's, but fine with i7 9xx's, I'm told). Do check in the OC sections on how to run cooler OC's.

OCCT/Linpack is the most stress I have found on my rig. Generally the temp gets right up there in 10 - 15 minutes, stays there, fluctuating only with ambient temps. I use OCCT/Linpack for all of my fan-testing.

Your cpu may be putting out too much heat for your H50. But at 3.6GHz you should be running 20c less. You'll need to check your airflow and your TIM. Generally, thick applications don't transmit as well as thin layers.

The H50 is not the greatest cooler, but it should do better than what you're getting. Reversing the airflow, pulling in cool outside air, will get you a few degrees, but not 20c.

Should i try flipping around the exhaust fan on the side so its an intake fan?

cause then i would have air coming in the front and the side and out the top and back

Did you mount the H50 fans properly? With the push/pull configuration? Because they're maybe the 2 pulling or pushing... It's the only explanation I have to such high temps...

well you got the block on the cpu then you have a radiator+fan that mounts at the back of the case. Theres only 1 fan to mount. It is set up to exhaust.

I am a bit perturbed. i mean i havent touched anything inside my computer for quite some time maybe a year or so other than to blow dust out once in a while. I remember my temps were lower when i first put it together maybe by 10-15c.

But yeah ill just say one more time how the fans are all set up

Intake in the front
exhaust out the side
exhaust out the top
exhaust out the back

maybe set your side fan to intake... but it will only drop a few degrees (if it drops something)

I don't think any of it would explain 95c on only 3.6GHz.

OP, you should look inside your rad. At 1 year, it my have gotten gunked inside. Using a hose nozzle from tapwater might dislodge gunk. Dishwashing detergent for hand washing dishes (not the dishwasher), then a garden hose. Toothpicks. rubbing alcohol. Etc.

That's all I can think of that would increase your temps 10 - 15c. Yes, your case airflow needs improvement (click on my profile to see what I prefer). But That was all in place a year ago. The only things that might have changed are things that fail (e.g. - front fan) or things that get dirty (e.g. - a filter; your rad; etc.).

Keep looking before you do anything radical.

Hmm i blew about 10lb of dust out of there and oriented the side fan so it is an intake but just looking at idle temps they are maybe 2-3c cooler? Not much.

That H50 how am i supposed to tell if there is something wrong with it..? I cant really disassemble it can i?
