[SOLVED] Heat issues with my Intel i9 10850k - Incredibly stressed and confused

[surhud]

Recently, some issues have been arising from my CPU. I have been having temperatures and throttling issues with a very good AIO cooler. In the BIOS settings, I disabled the turbo boost setting. After I did this, my PC was significantly less warm but now I'm having a throttle and weird single-core issue. I've re-applied the thermal paste on 3 separate occasions, checked if the PWM header was in the correct 4-pin slot, reset BIOS, cleared CMOS. I've tried everything I can to ensure that this okay but it's not working still. I'm really tempted to go to a local tech place and get it sorted there but I wanted to see if anyone can crack the case of what this could be? It's been creating a lot of unneeded stress. I have also not overclocked my CPU, and all fans seem to be running fine. I'm incredibly confused.

A Benchmark from Geekbench of my CPU - This is quite strange, my single core is not performing, and is performing at the bare minimum. The temperatures were stable when this was occurring. But my multi-core side of the test created a roar in my PC and throttled my CPU. I was hitting 100c temperatures.

Sometimes, my idle temps go from 35-40, to then high 40s and sometimes 50? Whilst gaming on Forza, it fluctuates from 70-80 sometimes even 85. When playing Valorant it hits 70-80, when playing CS:GO it's low, but CS:GO is a low demanding game anyway.

Here is a benchmark that I couldn’t even complete in Intel’s Extreme Tuning Utility.

How long have you had the cooler for? Pumps do eventually fail and looks like it's on it's way. 2~3 years on average.

It’s been 2 months since I’ve purchased this cooler. This is a new build. I’ve also included a benchmark that I ran from Intel. I couldn’t even finish the benchmark with the CPU hitting 100C.

Make certain that MCE is not enabled int he BIOS, which would try to run all cores at max turbo of 5.0GHz or so under load, often resulting in overheating...; it would take better cooling to sustain that, assuming the Vcore settings are not overly aggressive from the mainboard manufacturer/BIOS

If HWMonitor shows all cores at 5 GHz, then MCE is enabled....and your current cooling setup is not prepared /adequate for that.

You can, via Intel's XTU, easily tweak/adjust Vcore slightly lower and/or lower all core multipliers until a happy medium is achieved.

(No certainty that every 280mm AIO will handle an 10850K easily)
