whenever I play a game and get to 80+ degrees with the CPU my computer makes a loud constant beeping sound (don't know which part of the computer is responsible for it), I'm pretty sure it also throttle to get it back down to 70-ish degrees because it never stays above the 80 for more than 5 sec.
if important it happens in plenty of games but the most consistent one is kingdom come deliverance, after an hour or so of playing it starts going to the high 70 and spikes sometimes at 80+, my graphics settings in the game are set to low.
also, I reapplied thermal paste around 2 months ago and changed to a power plan that "maximum processor state" is at 80%, it did reduce a little bit the temperatures but still not enough.
as said i have a:
CPU: ryzen 5 2600
GPU: rx580 8GB
and 16 GB of RAM
please tell me if you need any more information in order to help me.
