CoolerMaster 212X on i5 4570 : High Temps

Guest · Jul 25, 2016

I just bought and installed 212X CM on my i5 4570. I runned prime95 and at full load I went 80C. The tests I've read arround internet showing an average of 55C for most installations.
My ambient temperature is arround 30C
I have 3 other fans in my case. A big one (200mm) on the top. A big on the front that brings air inside and a medium one rear.
I've read a guide on tomshardware about the center screw of the X mount that you need to tighten and nobody telling about it. Any thoughts on it? Some people also saying that the paste they provide with CM 212 is bad, others that's very decent... Help?

I actually have this cooler with an i5 4670K at 4.2 Ghz, it gets to about 68 under unnatural loads on aida64 or intelburn test. The paste is not terrible as people say as it does the job pretty well for the cooler. I see that your room is like british summer for me at 30 C which I consider too damn hot lol. But never mind that. I done some looking around but what I gather you should not use prime95 with haswell chips any way, and 80 C at your 30 C ambient seem pretty normal. Whats is your temp in real world tests and other synthetics other than prime 95?

With cpu-z stress test my temp was stable @ 55C
Playing civilization 5 during AI turns won't go past 55C too.

Also what I find mysterious is that the temperature rises instantly when I begin a stress test and lowers instantly when I stop it. Is that realistic or temperature is just a function of the fan speed only and not really measured with sensors?

Then it looks like you are fine, and that does happen. Prime95 "apparently over volts" the cpu not 100% sure but I was only briefly browsing ( more volts = more heat output). You have to remember using this stress tests are mainly to test the stability of a CPU when doing overclocking and other similar things. You are actually putting 100% load on all threads which is not normal in every day use as its a synthetic test. If you're getting up to about 75 C tops in games or benchmarks I would say its fully fine as your room is quit hot as it is.

Also iddle temps with ambient temp 30C as said above are 40C at each core. Normal too? Given the ambient temperature.

Yep I would say so. Just try a few games and run a benchmark from 3dmark and use hwmonitor to see max temp afterward. Let me know how it goes. Just for 100% piece of mind
