hyper 212 evo high temps?

[Xulu132]

Just got a 212 evo and ran prime95 for 20-30 minutes. The first thing I noticed is how the stock fan was keeping the CPU cooler when overclocked to 3.9GHz (4690k) the stock cooler was keeping it around 81c which was still too hot for me, that's the reason I got this cooler.

 

Running at idle the temperatures are 10c cooler, nice! However under prime95 at 3.9GHz is still running at 80c+!

 

The cooler itself is cold to the touch, only the bottom is warm, this leads me to believe it's not got good connectivity to the CPU, I'm about to take it apart and check if the thermal paste spread out etc but any ideas would be helpful .

DON'T USE PRIME 95

 

It overvolts the balls off haswell. Download XTU for your stress tests. Prime can hurt haswell cpu's if ran too long.

 

https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24075 Memory stress test is the most stressful on the cpu. You can also manage overclock though the program safely, and it saves to your bios on application of settings. 

 

Aida64 is another good option for stress testing.

Thanks, I was aware and watching voltages but I will go ahead and use that instead.

 

Edit: even with the voltage set to static instead of adaptive, can prime95 still overvolt?

Try reseating and use the "star" bolt pattern.  I overclocked my bloomfield and thier hot as hell from 3.0 to 3.5 and im only 10 degs hotter than Non OC.

Yes, you have to be careful and make it static on other cpu's because I think prime overvolts on any cpu set to adaptive. I am not 100% on that but I do know it overvolted the crap out of my cpu.

First problem I have is that I'm running at too high of a voltage myself, I as recommended didn't put it past 1.25 I'm currently testing 1.20 volts at 4.3GHz and it's seems to be stable at 50-55c.
