Question CPU Overheating, New Build

[alfuego]

Hello, specs below:
z690m-itx
i5-13600k
blackridge cooler, swapped out fan for noctua a9x14
contact frame
4080 fe

CPU keeps overheating. When I run cinebench, all cores instantly hit 100c. When gaming temps are in the low 90s.

I've took the system apart about 5 times now and tried reapplying the thermal paste.
Also had the CPU RMA'd and this is now a new CPU with the same issue.

Would love help, I am thinking its now the motherboard and that something my be wrong with the pins.

Thank you.

Lol, you are using a "92mm" pancake cooler on a 13600K and don't know why it is running hot?

You have a 125W CPU running under a 95W cooler...

If you're looking for a decent cooler on a budget for this thing, the Deepcool AK500 goes for around $55 USD and if this video is anything to go by, will keep it around 75C (21-22C ambient) in a Cinebench R23 run.

mITX system with a 4080 inside?

What case do you have?
What fans in the case?

it was a recommended air cooler in the Form T1 Reddit page. Are there any recommendations or fixes you think I can try?

Yeah I definitely didn’t look into this, it was just an air cooler that would fit with my case. Would you recommend any other air cooling solutions?

The case is the Form T1
And I have two Phantex T30s on the top as exhaust

Oh man that won’t fit into my case, I’m using form T1 v2 so that’s why I had to go with a smaller air cooler

The only cooler I can think of that would maybe handle this is Corsair's H5-SF. Otherwise you're going to have to power limit the CPU.

Ok, Form T1 webpage says 70mm as max height for CPU cooler.

The blackridge cooler is 47mm tall. Is there no way to mount a 120mmx15mm fan on top of the heatsink?

For SFF builds, I'd recommend spending some time on undervolting (not necessarily underclocking, they're different). In SFF builds where cooling is limited, it's ever more important to be running CPU & GPU at optimum efficiency. Stock voltage curves are conservative.

Also, what country are you shopping in? (For component availability)
