Question cpu overheating and freezing pc when opening and closing games

[AsheRexxed]

My pc CPU has been overheating and turning off and freezing, I've tried everything, we bought a new cooler, set fan and pump to max, the last thing I did was change my bios setting from pmw to dc after i had a huge crash and the CPU debug light came on, if this doesn't fix the issue I don't know what to do , could that have been why the pump wasn't cooling the pc even if I had an app that was making my fan run at full speed (fan control)

PS I didn't want to change the fans speeds in bios until a last resort

edit: specs-
CPU: ryzen 7 5700x
CPU cooler: Poseidon elite argb 240
Motherboard: msi b450m pro m2 max
GPU: rtx 2060 super oc
psu: 750 watt

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

Your system's specs are incomplete. How is the AIO mounted in your case?

Stick to one thread unless you want spaghetti brains.
