You don't have to buy another entire PC to upgrade the amount of ram. Also, just because you're by a fan doesn't mean your PC isn't running too hot. For example, a PS5 pumps out 37+ degree C air out of it. If I set it next to my ac it doesn't mean the PS5 isn't still pumping out 37+ degree air.
Are your GPU drivers up to date?
Are all of the PC fans working?
Did you install an app to actually check the temps instead of guessing?
Are all Windows updates installed?
Did you check the Windows Logs for error messages?
No one has suggested they buy a
