So i recently bought a new prebuilt PC with a i9 13900k and 4090 so it generates quite a bit of heat, im aware you can have 3 more fans at the top of the td 500 mesh as my radiator for my cpu cooler h150i elite lcd corsair is at the front and they only put in 1 exhaust fan at the back of the case. The issue is i wanted to put in more exhaust fans but they have installed the cpu cooler so it blocks the top of the case where the fan bracket is the cpu cooler wires are brushing against which is annoying. I can change it but i would have to rewire it all which seems like a pain if its not going to help temps that much. I can add one more exhaust in the top corner by the other exhaust fan should i do this or leave it as 1 exhaust 3 intake? Temps have seemed fine so far when playing games hottest ive seen the gpu is 72 and cpu like low 80s all at stock. Also should i get 2 120mm or 2 140mm as exhaust fans if i get 2.
