4790K Prime 95

Pentium 4

New member
Hello guys, I've been running my 4790K at 4.7Ghz using 1.24v for 2-3 weeks now but today I just randomly felt like trying to bump up higher. So naturally, before I start OCing, I run a few quick benchmarks and decided to download Prime 95 as I hear so much about it (use Aida for my stressing). To my surprise running the small FFT test caused my core temps to shoot up to 94oC, 98oC, 96oC and 85oC according to Real Temp and HWMonitor.

What is going on, because temps during Aida tests for 6h+ never managed to exceed 72oC and during prolonged gaming sessions I have yet to see CPU temps of 60oC. Is this normal for that specific Prime 95 test or is something else going on? Quite literally as soon as I start up the test the temps shoot. I'm using a H100i with SP140s.

Thanks for your help.
 
Have you tested Intel Burn Test? It would probably give you higher temps (if not completely crash your system. Applications like this are desinged to rape your CPU, it's worse than worst case scenario.
 
Hey there, I have ran IBT for 1hour and the temps hovered around 76oC which was much better than them shooting up to nearly 100oC in Prime 95. I've read around a bit and found that Prime ups the voltage on Haswell chips and it's better not to use it, so I'm just running with Aida and others now.

Thanks.
 
Yea prime was never updated to the correct mapping for Haswell so unless you are testing for something specific then it is best avoided. The next best stress tester is OCCT.
