Cooler Master 212 EVO idle CPU temps higher than stock heatsink

[Mixolydian]

Hello everyone,

So I just installed a Cooler Master 212 EVO in my PC, replacing the stock heatsink that came with my i5-3570k. However, the idle temps are 40c, which is higher than what my stock heatsink temps were. Am I missing something here? Everything works, the fan spins up good, just when I go into BIOS and ASRock Extreme Tuning Utility, i'm a bit confused on the CPU temps. I thought that getting this aftermarket heatsink would bring my temps down? Any insight would be greatly appreciated.

Thanks!!!

Did you remove the old thermal paste before installation? And if you did, how much did you reapply?

Also make sure that your screws are screwed all the way in.

Sounds like it isn't seated correctly. What are your load temps ?

I removed the old thermal paste using Arctic Silver thermal material remover, and applied about a rice sized grain of Arctic Silver 5 thermal compound

It seems like it was seated fine, I tried wiggling the heatsink after I screwed it in, and there was no wiggle room. And after I initially set it down on the CPU with thermal paste, I made sure to move it around a bit to make sure the thermal paste gets well spread out

What thermal compound did you use? I know certain compounds take time to cure (AS5)

That's what compound I'm using, Arctic Silver 5. I've never read about compound taking time to cure

200 hours of curing time to be exact

What were your idle temperatures with your stock cooler? And what are your load temps now? If they aren't too bad, I wouldn't worry as they may get better over time.

Just to clarify, these are stock settings no overclock or anything ? The 40c temp you said was while in BIOS and via a Asrocks program in Windows ? Download Real Temp and see what that gives you for temps.

My stock cooler was idle around 40C, at load around 70C.

I'm just confused as i'm not getting better temps with the Cooler Master 212 Evo

Stock settings, no overclock. Using Real Temp, here's what it's showing now

Core 1 - 41
Core 2 - 44
Core 3 - 44
Core 4 - 42

I haven't tried putting it under load yet, for fear of over heating my cpu.

Can you download CPU-Z and see what your voltage says? I know some boards have a tendency to over volt your CPU when you don't even need it. (Common on X79 boards it seems, but I've seen some Z68/Z77 do it as well)

Well here's a comparison to my temps, this is having a few tabs of Chrome open, music playing via the web. As a note im overclocked to 4.2ghz with a manual offset voltage set to .020 also using a 212 EVO with Arctic Silver Céramique for a thermal paste. Playing Battlefield 3 for example on a 64 man server I can reach a maximum of 60c on a core with 70-85 % CPU usage. Prime95 blend test yield's 59c 66c 63c 63c after about 15 minutes. I can revert back to stock and repost if you would like so you can compare though.

Core voltage is 0.888 V
