I have a FX-6300 (stock cooler), an RX-570, and a single case fan, so my PC gets pretty hot. I just tore down some old E-waste servers and got some beefy fans, I can drill holes and add dust filters anywhere in the case (Its also just an e-waste junk case), so where should I mount them? I have 90mm, 120mm, and 180mm fans. Would placing one on the side facing my cpu cooler help it? or maybe one sucking air out of the top? Positive or negative pressure? Any advice is appreciated! thank you.
