I have a 1060 6gb installed and when playing PUBG, while the side panel on with 100% fan speedss, it reaches 72 degrees celsius, but when I take the side panel off it gets to 48 degrees. I have 2 front, intake fans installed and one exhale on the back. The sidepanel is closed, with no holes, it's just a metal sheet with plexiglass . I can not use a fan on the bottom of the case. Should I install 2 more exhale fans on top? 120mm ones.
