CPU overheating and loose heatsink/cooler

Hi, recently my boyfriend and I cleaned out his computer, and it was an absolute mess of dust and debris, overflowing and very dirty, but working fine with no issue apart from GFX crash due to overheating (nvidia 470), which is notorious for overheating, I know, during taxing video games. The heatsink/cooler/fan (not sure what it is officially called) on top was unwound from the rotating pins but still hooked up and after the cleaning we booted the computer but it crashed multiple times on multiple boots, it finally worked one instance and I installed a program to check hardware temps to rule out issues, and the CPU was running at 99C and the motherboard at 81C.
We further cleaned the fans/heatsink with no change in temp.
I put my weight with my hand onto the device/fan center and it went down to 55C.
The device has four push pins that rotate to lock and I locked it afterward thinking that the issue would resolve. The CPU is now currently at 65C at idle which is still too hot and motherboard at 56C.
Question is, should there be more pressure? Is it too loose? How do I fix it? Or is it an issue of the thermal paste not working anymore or something like that, in which case how do I apply it? Any very cheap/fast solutions?
Big thank you!

those push pins aare notorious for not properly engaging

take off the side panel--the one thats at the rear of the motherboard--usually the right hand side one

and you should be able to see if all 4 pins are properly engaged through the rear of the motherboard
Since the cooler was loose, it loses contact with the thermal paste, so you need to reapply the thermal paste if you want your temperatures to go down more.

Note: The arrows on the pushpins point in the direction to remove the Intel stock cooler. The other way is locked in place.
