Hi fellow Toms, I need your advice on the cooling of my outdated desktop PC case. I attached some photos of the case, any advice is much appreciated. I do not plan to buy any new case just yet, my budget now simply couldn't stretch any further. The case comes with a tiny 8cm fan as rear exhaust, and I have 2 extra 12cm fan sitting around. I wonder how can I utilize them to maximize the airflow? Thank you for your time.
