i7 920 hits 75c IBT at 4GHz Clock Speed?

post #1 of 15
Thread Starter 
I have the h-50. I know it's watercooling, but i kind of see it as air cooling too, because of the fans attached to the HS block ect. So i am hitting 75c if i stress the CPU with IBT. It's fully stable, the temps are a bit too high. When i installed the h-50, i put the block onto the CPU carefully and screwed everything into place til the screws would turn no further, so am guessing it's installed fine.

Am using stock fan and a case fan for push/pull. Thermal paste is the one that came with the h-50 which i find to be good. Should i have the fan to intake air directly from the outside like corsair suggest? will that help?

I might try to do some cable management too, and reverse the front fans to blow out rather than suck in, only if i have the corsair fan intaking directly from the outside air, again, corsair suggested this.

Thank you for the input. Am glad it's not 75c in games haha!

well. haveing good air flow is a must. i would replace fan and get 2 for push pull on rad. Also haveing air from rad to Blow Out side case is best. Wont dump heat into case. i got water for gpus. not for my i7 . i7 are hot beast tho.

You didn't mention what voltages you are running or what your ambient temps are, as they will definitely factor in. Also, as GfhTattoo said try push-pull and different air flows. I know the H50 will run cooler if you run it as intake instead of exhaust.

First IBT is the hottest test out there for CPU testing - under Prime95 your temps should be under those 75C - you should check that. If you put the fans to take air from outside - the temps should fall cause of the cool air outside the case. Here is a test made with different types of installation of the H50 => http://www.clunk.org.uk/reviews/cors...ew/Page-6.html

Well, i have it as exhaust.
My voltage is 1.23v at 4Ghz. No idea about ambiant temps or whatever you call it. It's not that warm tbh.

I will, change to intake, tidy cables, sort front fans out to exhaust and keep 200mm fan for exhaust.

1.23v at 4.0Ghz stable is immense!

Also in regards to your first post usually proper watercooling loops with radiators have fans so kinda the same.

Didn't read other posts, but 75c is absolutely fine in IBT which is usually around 10c hotter than Prime95 which is 5-10c hotter than normal "heavy loads."

I would not recommend, but would not consider 85c out of the question in IBT.

Yeah, i instantly thought this as i posted.
And as for the low volts on the 4GHz, if i add more volts, the PC hangs and will not boot. Ive i lower it's volts, it's 100 percent stable. Very strange, but cool

Well, if it's stable at a really high temp, the CPU can obviously cope, just for a one off stress, but still, am going to clean the PC and sort it all out. Might help my GPU as well!

I didn't notice you were using the H50 and not an air cooler. Your gonna wanna run maybe 20 or 30 runs of IBT on max/very high because the liquid in your cooler will heat up over time.

Just make sure your temps don't go over 95c ever and of course the lower the better.
