I recently installed a brand new processor onto my PC, an AMD A8-7680. A few days after doing so, I noticed that my PC was heating up too much (CPU reaching 97 degrees celsius on HWinfo, Motherboard reaching 118 degrees celsius). I purchased an 80mm fan which I installed as an exhaust fan, then considered purchasing a 120mm fan as an intake fan which I planned to install on the side panel of my case (Fortress Magnus Micro ATX). However, a friend disagreed with my plan, stating that it I shouldn't install a fan on the side of my PC, even though it looks like the case can support it. What should I do?
