If 75°C is that highest temp while gaming, that is fine, and you should not worry about it.i thought the gpu always run hotter than cpu but they both run at the same temperature
should i buy a better cooler?
im using ryzen 5 3400g and rx 590
i can change the fan profiles in the bios right?That sounds right for the stock cooler, you shouldn't have any issues with throttling until you reach in the '80s though. If you are uncomfortable with the temps you can change the fan profiles or repace the cooler, just about anything on the market will lower that by 10 degrees.
DEEPCOOL GAMMAXX 400 $19
It's cheap and highly effective though it can be a little noisy for some people.
Several waysi can change the fan profiles in the bios right?
