Question Gaming pc, CPU overheating randomly. Tried redoing thermal paste and removing dust from case. Anything else I can do?

Hi, so my PC was running really slow for a few days, so I used Speccy and my CPU was running around 95-100° C. When not doing anything it runs at about 65. As soon as I do anything, file explorer, websites, etc. It shoots back up to 100. I read online that it could be dust in the case, so I dusted it (was really dusty), and I bought thermal paste and reapplied it. After redoing the thermal paste yesterday, it seemed to be fine, would sometimes spike up to the 90's but would come back down. But now it's overheating again back to the 100's. Also, did I maybe damage it by leaving it running that hot for a few days? I'm not sure how to tell what cooler it has, it's an iBuyPower prebuilt. Also, all fans are working. Any advise?

What thermal paste did you use and how did you apply it?

Some AIO water coolers plug up internally or the pump fails. Your computer should not be reaching 100°C because you opened File Explorer and a few websites.

Here is a similar 10 core CPU running a full load Cinebench test with all cores at 4800 MHz. Maximum core temperature is less than 60°C. Cooler is a Corsair H115i.

After doing some research, I definitely think its the cooler. I didn't even know I had liquid cooling tbh. Is there anything I can do without replacing the whole component? Strapped on money right now. Also, I took off the case panels and it's still running hot around 90-95° C but it isn't lagging. If I keep running it this hot until I can afford a new one, will it break other components?

I'd try mounting the radiator with the pipes at the bottom. Air trapped in the system will rise to the highest point. Your pump may be sucking on bubbles of air instead of coolant.

Rotate the radiator through 180 degrees, with the pipes at the bottom and see if temperatures go down. There are loads of reviews on YouTube showing the "correct" way to mount an AIO system.

bro why not trying a better cpu fan? 11th gen i7 is a heavy processor.
try a strong cpu fan-liquid cooler
