I recently built a new PC, but did not order any extra fans for my case. I only got 1 extra (the 120mm exhaust in the back) since there otherwise was no exhaust fan in the case, only 3 120mm fans in the front. I keep getting temps of up to 84oC when I am gaming. Is this a normal gaming temperature for a ASUS TUF RTX 2060 6GB graphics card, or should I be worried and maybe get extra cooling?
