i7-7700k OC (Not Delided) hitting 50°C at about 10%

Hey!
I've an i7-7700k OC 4.4GHz 1.2V and it's hitting 50°C when it's in "idle".
It's cooled by an H115i (Corsair).
Is that normal?? Should i replace the thermal paste? (applied about 1 year ago) or change the fan curve?

Hi DarkWalker19

First off, you're underclocked by 100MHz, the i7-7700k stock boosts to 4.5GHz.

50c at 10% load does seem high but it's hard to say if you should replace the thermal paste.

How are stress testing/gaming temps ?

In Game sometimes it goes between 70°C and 80°C
Under stress test (CineBench R15) 90°C


Should i post here my BIOS settings?

Sure you can post your bios settings.

With 1.20v and hitting 92c, I'd say yes, replacing the thermal paste should lower temps.

I delidded my 7700k and here is results with far cry 5, this is with 1.440v.

Thank you for the bios screenshots.

Is the H115i pump running at 100% ?

You may can lower the cpu system agent voltage and cpu standby voltage to 1.15v.

I'd repaste the cpu and see how temps are, how are you applying the thermal paste and how much are you using ?

Ok now in idle (4.4Ghz 1.2V) it's around 40s °C and on CineBench it's around 70s °C ------ After modifying this Post, it's around 35°C-------

I applied a little bit of thermal paste (Rise grain) after cleaning the Cpu "shell" and the Waterblock

Now i'll try to give it 4.5Ghz and lower the Voltage to 1.15V

So i've to lower the CPU core voltage override and DRAM voltage to 1.15V too?
Is it ok if the color changes from white to yellow??

Dram voltage should be 1.35v

You can try CPU Core Voltage Override at 1.15v, if it doesn't want to go that low use a negative offset.

Yes, white, yellow and purple are ok, red means you're in the danger zone.

Temps are looking much better. For the thermal paste I use the size of a small pea and spread it evenly over the entire cpu.
