Hi!

I know this is a common issue, but I didn't find helpful solutions on the internet (other than re-applying THERMAL paste).

When running Prime95, temps goes up to 100°C very quickly, voltage of 1.23v, thermal throtling on 2 cores.
But at idle the CPU runs at 4.4ghz on 1.23v at a healthy ~37°C (or less), which is good.

I find it strange that the CPU temperature is good at idle, but very hot under 100% load. Is the voltage to high?

Room temperature is around 20°C. Here is the spec of my fresh build PC:
Case: Bequiet Silent BASE 800
CPU: i7-4790k, stock speed
CPU cooler: Bequiet Dark Rock 3
MoBo: MSi Z97 Gaming 5
OS: Windows 10 x64


Thanks!


P.-S.: Re-applying thermal paste is the last option because this cooler is very hard to install  Just so you know Prime is about the most aggressive CPU test app out there...there are others.
If you aren't seeing those temps in daily usage i wouldn't worry.

P.S....are those stock volts...or are you OC'ing ? ?What stress test do you recommend for a less agressive, more relevant test to see if the cooler is installed properly?
Thank you!I'm using a 4770K that is entirely stock aside from the paste (speed, voltage, cooler, etc.) and other than a higher idle temp (around 50 degrees) I see the same behaviour running Prime95.

I'd argue that being able to run Prime95 for more then a few seconds without a thermal shutdown or a fire is probably reasonably good evidence the cooler is installed properly. Quote from: patio on January 28, 2016, 01:21:19 PM

BTW ...you never answered if you see those temps in daily usage...

Then you have no worries...

Do you thing the motherboard gives more voltage than needed?
