my room temperature is about 25 C, why my chips temp always above 82 C? I already set the fan to 95%.
I rebooted it and it's still the same.
Is there a way to reduce the chips temp?
Improve your cooling on it or underclock it. Not sure if underclocking will void your warranty, or if only overclocking it will... Proceed with caution. When I underclocked mine to 575 I saw a drop in temps of over 4 degrees:
