hello i have 4770k and h100i cooling asus maximus 6 hero mobo my question is i clocked my cpu at 4.6 ghz 1.2vcore and when i do really hard rendering 100% cpu load my cpu temp goes to 80c while my h100i temp is around 30c when i stop rendering(drop cpu load to normal 1-10%) my cpu temp goes from 80c to 30c in 1-3 sec is that okay? sorry for my bad english and the mess and tnx for helping
hmm there are a few variables but I think these temps are kind of normal especially with the 4th gen chips. They are hot and bad overclockers.
That said there are some things to think about:
How much thermal paste did you use, did you remove any film/plastic from the cold plate when installing, how high are your fans. There are probably some others but yea.
Sounds a little high for 1.2 vcore with closed loop, but the fact that you're stable at 4.6 with that voltage is almost a miracle on haswell ( I can't even get to 4.3 on 1.2v).
Could try adjusting your fan profile to ramp higher at certain temps.
i got 4.5 on 1.2V with ~55C playing games and 65C while rendering with a nh-d14. fans spinning pretty slow. i think you have a problem sadly. the temperature drop from 80 to 30c in 3 sec is normal.
sounds like you didn't properly mount the cooler on your CPU/thermal paste, since the cooler itself isn't getting very hot. I would say take the waterblock off the cpu. clean the thermal paste off, reapply thermal paste, then remount it.
BTW, 4.6 ghz stable at 1.2 volts? you were blessed by the silicon gods.
tnx for reply i will try btw guys can u suggest me some good thermal paste?
