I have recently overclocked my cpu up to 4.3 with hyper evo 212 installed

This is my specs :
CPU i5 3570k
M/B: asrock z77 extreame4
GPU: gtx 980 evga
RAM: 12gb -corsair vengeance
HDD: WD- 1TB
Cooling: hyper evo 212
Monitor: QNIX-2710
PSU: 850W CORSAIR MODULAR
Case: Phantom 410
Keyboard: Microsoft
Headset: Aurvana live 2
OS :WINDOWS 8.1

I stressed my rig with intel burn test (high preset) ten times:


What is your opinion in this temps with vcore near 1208 v

Hi,

You do with it what you want, but >80 at full load seems rather high to me for long term 24/7 usage. If it was me i'd lower to x42 and try to lower Vcore a tad.

Generally advised max core temps for long term usage are 75° or 80° depending on the source.

Personally I have full load max core temps in low to mid 60s for 5820K at 4.25G with 1.100V and NH-D14, but I believe I was lucky with silicon lottery...

Thank you Neutr1n0 for your fast reply also nice temps with your chip . I was mad to see my temps going to 92 c while stressing in Intel burn test (high preset) so i wanted to check my applied thermal paste and it was splashing out of my heat sink contact area and processor although i used the double rice method to apply thermal paste .

so i did some research to find the best method to apply thermal paste(as mentioned in puget systems website) to get the best temperatures and best method were used is the X- shape as it was getting the least temps overall while full load stress.


I did teh same test after cleaning everything and reapplied thermal paste in 4.3 Ghz and got this great results :


I am getting lower temps by 12 c by only applying much less thermal paste quantity and forming x shape and was happy with it .

i plan to reach 4.5 ghz later and will see how my temps will be .

Any suggestions are welcome .

Nice improvement! But your hottest core is still at 80 max...

What have you set for LLC (load line callibration)? LLC give increased stability on a certain voltage setting (by eliminating vdroop) but also increase power usage. Too high LLC setting could lead to 'negative vdroop' so voltage increase when going from idle to load and that will give extra heat.

If it would be stable at same voltage with less LLC your load temps will go down. Even seen claims of having lower temp with significantly higher voltage and LLC disabled compared to lower voltage with LLC enabled. Could be worth a try...

GL!
