Abnormally High Haswell Temps

post #1 of 3
Thread Starter 
I just got the new 4770k about two days ago and have been stress testing my rig with the stock intel air cooler. While running the small FFT's in Prime95, my CPU temps went up to 95C in just a few seconds. I suspect that with further running of the small FFT test, I would see temps higher than 100C. After seeing such a dramatic increase in temps, I shut off the test and started a blend test. The blend test gave me slightly lower temps in the 75-80C range but I think that is still to high for me to let it run for hours. I have heard that the new Haswell temps are high but these temps just seem rediculous at stock voltage and clock speed. Any advice on how to get these temps down? At this point, I plan on buying at least a Hyper 212 EVO or maybe a H100i.

The stock cooler doesn't do a good job when you are running stress tests like that. The boards, in Auto, give additional voltage when running AVX type stress tests like Prime95, and that can cause the temps to spike significantly. An aftermarket cooler is recommended if you intend to run loads like that routinely (the stock cooler is fine for everyday tasks) or if you intend to overclock at all.

Do yourself and your CPU a favour and get an aftermarket cooler.If you don't want to spend much,a hyper 212 plus/evo would suffice.I ran my Ivy i5-3570k @ 4.7Ghz with 1.3V using a Hyper 212 plus and i get max temp of around 85 in IBT.On stock clocks,heh,around 55-60.My daily OC though is 4.3Ghz which gives me 66C max on IBT and avg 53-54C on blend in Prime95.

Intel Stock cooler : 90C @ load with 14C ambient
Hyper 212 EVO: 50C @ load with 14C ambient
That's 40 degrees lower,it'll suffice your needs.
