[SOLVED] FPS drops when CPU reaches 60+ degrees Celsius

[hhsb2424]

Good evening everyone,

I have searched pretty much everywhere and have yet to find a solution. Just put together a mini-ITX and have noticed that when my CPU temperatures reach 60+ Celsius (especially 70+ Celsius) my frames drop dramatically (80s/100s --> 30s/20s). When I remove the side cover of my case and my CPU temps drop to sub 60 Celsius my FPS rises back up to 80s/100s. This is where I'm confused...

1. My core clock never changes (~4.006 GHz)
2. Program (Warzone) isn't being thermal throttled by CPU according to Task Manager
3. GPU is sitting at a comfortable 55ish Celsius
4. CPU should be able to perform well over 60+ Celsius
5. Reapplied thermal paste (very slight to no change)
6. Percentage of CPU is sub 50% sometimes in 20% range
7. Intel stock cooler is maxed 100% fan speed

CPU: i5 10400F
RAM: 16 Gb
GPU: 1060 3Gb
Power Supply: 650 watt Gold
MB: Asrock H410m-itx/ac
Case: Fractal Design Node 202
Storage: NVME 1 TB

Would like to run the game (Warzone) at 80s/100s FPS with CPU running in 70s degree Celsius if possible, which I feel as though it should be.

Thank you for your help!

It's a coincidence. Something else is 'throttling' when the cpu is climbing in temp.
The cpu shouldn't throttle until 100C. The alternatives are:
-for the user to go into bios and change the default throttle limit to a lower value, you know, for safety reasons. There's no real need to let it get that high anyway.
-for the motherboard VRMs to thermal throttle.
In either case, the cpu should drop clocks.

If the cpu isn't throttling, the VRM isn't throttling, and the gpu isn't throttling...
I see one device in the list that could throttle and kill performance when the chassis is closed, but doesn't when it's open: the NVMe drive.
Taking a look at some inside photos of the FD Node 202, I can see how that part might be running a little toasty.
Gonna need one of those M.2 heatsinks if it really is the NVMe throttling.

Perfect I’ll check it out this weekend when I get a chance! Thanks for the reply, I’ll post my findings when after trying out the suggestions.
