I've recently built a new PC. I will be mostly gaming on it, though, not too intensely. I've OC'd the CPU to 4.4Ghz using this methodology:

http://www.overclock.net/t/1198504/complete-overclockin...

It seems to run hotter than what most people with similar setups achieve, so I'd like some input.

Here are my parts:

i5 3570k @ 4.4GHz
ASRock Z77 Extreme4
8GB DDR3 (1600MHz)
Hyper 212 Evo
AS5 Thermal Compound
Cooler Master HAF922 (Stock fans)

Ambient room/home temperatures sit around 25-26C.

Computer sits on the floor, but elevated a few inches. I'm using hanging wire office trays (upside down) to do this.

Here is a screenshot to assist troubleshooting the issue:

DAMN !! that's too hight !!! buddy , check the temps using another software (HWmonitor ) maby the software which you are using is reading it wrongly !!

if this is true then your CPU in risk with this temps , you should downclock it to make it run safely .

Check your CPU temp in the BIOS to get a definite answer. If you don't want to do that then download HWMonitor, SpeedFan or CoreTemp. You could have a monitor sensor problem. Those temperatures seem absurd at over 90 Degrees. However if you seen below they aren't over the TJ max.

I did tweak the settings in my BIOS, from the recommendations for Offset voltage in the guide above. I enabled all my C States (i.e. C3/C6/Package C).

These temperatures are not constant. They are just the peaks during the PRIME95 blend test, specified in the guide above. The temperatures typically stay around the mid 80's and occasionally peak in the mid 90's as seen above during certain parts of the testing.

I also have an issue where the computer will not wake after it goes to sleep for an extended period.

Any more advice would be welcome.

Hyper212 evo + 3570K @ 4.2ghz (at about 1.25v) should be getting around 65~70C with prime95 load @ ambient temp of 25C, about 40~45 delta. And that is the hottest core max. I recommend that you check it out once more with HWMonitor, run prime95 for 30min, with side panel open, and see the result. If you still get 90C in HWMonitor, crack open the case, and reinstall cpu + heatsink again using another thermal paste, using the well known bb size apply method. If thermal readings are correct, I think you have heatsink installation or heatsink problem.

HWMonitor doesn't report the temperatures as high as RealTemp does. I have been assuming that RealTemp was the more accurate of the two monitoring tools.

I have been debating about reapplying the thermal compound and reseating the Hyper 212. I'll do this tonight and then run the tests again, using the same BIOS setup. Hopefully, this results in some lower temperature readings. I'll post an update after this has been done.

I will post a screenshot this evening with my update.

This installation of the heatsink was done by spreading the thermal compound in a very thin layer across the whole CPU. I know there are many schools of thought, regarding thermal compound application, but does it shouldn't cause the temperatures I'm seeing, right?

Thermal paste application only makes a few degree difference, not 15~20. From my experience, the bb side worked the best vs the amount of work involved. Some other application methods may yield 1~3 degrees improvement, but I don't think it is worth the time, IMO, but you can still give it a try.

I think both RealTemp and HWMonitor are great. The differences can be ignored, IMO, because what you are looking for is not the 100% accurate temp, but rather to monitor the changes you see at idle vs. burn vs. per core, etc.

So I was able to reapply the AS5 thermal compound and reseat my heatsink. This seems to have done the trick. After running PRIME95 blend for just over an hour:




My only remaining issue, is that whenever my PC goes into deep sleep, I'm unable to wake it back up. I have all my C States enabled. Thoughts?
