The same thing was happening with my GPU so I underclocked and undervolted it to hell using msi afterburner and now instead of getting 85 C during gaming sessions it’s around 70 C. my CPU fan is always loud. i think the thermal paste is gone. I’m not willing to take my computer apart because where my computer is it’s really awkward and if it bricks itself i have the money to buy a new one. rn the package temp is idling at 46-55 C, jumping every second. min temp is 45 C. the max temp is 80 C idling according to hwmonitor. i’m getting spikes in high temperature that last a second or so but when I’m playing a game it can spike to 95-100 C
UPDATE: Disabled Boost and undervolted my CPU, now temp spikes are much more reasonable. Max idle temp after 1 hour according to hwmonitor is 53 C which is a lot better than random spikes to 80 C lol. thx to everyone who commented!
If you don’t feel comfortable fixing it where you are, search for a maker space. libraries in larger cities often have a maker space where you can get tools and expertise to complete these sorts of tasks. They may even be able to connect you with people willing to help for free. It’s highly unlikely that you will break your computer by replacing the thermal paste on the video card just ground yourself by touching a door knob or faucet before working on the system and don’t shuffle your feet on carpet in between the door knob and your workspace. That should eliminate most static shock which could cause damage to your circuits.
