New set-up, i5-7600k + Z270-A Prime + Cooler master Hyper EVO 212 - Idle already to hot?

Hi all,

Since my old set-up which is: FX-8320 + 970A-G43 was getting too hot because of VRM's and just a poor mobo, i did upgrade to i5-7600k + Z270-A Prime + Cooler master Hyper EVO 212. (further specs: GTX 1060 3gb, 16GB DDR4 Corsair vengeance 3000mhz)

I watched tons and tons of vids and topics and this set-up seems reasonable to me to buy since i can OC a bit with this cooler and its just a good upgrade imo.

No the next thing happenend; Since this was my first time building a PC i did put on to much thermal paste on my i5, i could tell because of the spills next to the CPU and idling temps were at like 55 degrees, gladly i didnt spill anything on the mobo or underneath the CPU. I removed the paste, added a new amount (peasize) and attached everything again.

idling temps are around 40-50 now. Still i'm worried, because when i run PUBG or a cpu stresser, temp goes up to like 75 degrees. Keep in mind i didnt overclock anything yet..


Are these temps normal? Can i even overclock? I did read and see tons of people that say overclocking to max 4,6ghz wouldnt be a problem with this fan. Still i wont OC, because i dont want to go over 75 degrees.


What to do?

  1. If u installed your cooler properly check your VCORE voltage using HWmonitor while stress testing with prime95, aida64 or Intelburntest. What voltage does it report during idle and load?
    What is your case? Does CPU fan spin? Slightly try to wiggle your cooler to confirm its mounted firm and not loose. Its a bit tricky to mount 212 properly for the beginner.

    I'm new to building PC's not new to technical things haha so yea, i'm pretty sure i mounted everything correctly. I even followed the manual from the fan. Vcore max = 1.311V and idle like 1.100V Case is a Cooler master K350, tho i removed the side panel atm. All fans spin, but there are only 2 fans, 1 rear fan that lets the CPU heat out of the case, and the CPU fan. Adding more fans wont do much i think since its a pretty small case and the airflow isnt that good.. when i try to wiggle the cpu fan it moves just a tiny bit, but not sliding. I mounted the screws and everything pretty well.

  3. Vcore is too high for stock speeds and your cooler, go to bios. Press F7 to go advanced, then open AI tweaker. Switch to sync all cores and put 48 (which is 4.8GHZ) then scroll down until you see CPU core/cache voltage, put it to manual and type 1.250v, press F10 save and exit see if it boot. Once in windows run tests again, check vcore and temperature. Temperature should go down if true voltage was 1.311v

    I think 4,8ghz is too much for this cooler?

  5. Doesn't matter what frequency you run as long as you can keep voltage and temperature under control. 4.8GHZ is what easy to achieve with evo 212, you can try to overclock higher but make sure your temperature is bellow 80C while gaming and you will be safe. It doesnt matter if u get higher temperature during stress testing becouse it will never be as high as during gaming/everyday use.
    Play with voltage and multiplier, check if you can increase to 4.9 at the same voltage. Your goal is to achieve desired frequency with as low voltage as possible but still keep it stable during gaming/stress test. Good luck.

    4,8GHZ @ max 72 degrees whilst gaming. Thanks a lot!

    -PS how do i know when i have set to low voltage?

  7. if voltage is too low, your system will blue screen, lock, etc....

    Your system will crash forcing you to reboot or will reboot by it self. leave 4.8ghz and decrease voltage by 0.010v each time and run cinebench r15 each time between. Once it will crash on cinebench r15 it will be your starting point. Now increase voltage by 0.010v and run Intel burn test for 10-15min at maximum, increase voltage by 0.010v until u can run it stable for 10-15min, dont be afraid of high temp unless its 90+, it will not damage anything during these short tests. So once u pass 15 min, just do your daily gaming if it crash again just increase voltage. This method works best and will find rock stable overclock.
