Hello, im building a new computer using a corsair h50 cpu cooler that comes with a 120mm fan (because the radiator uses 120mm screw holes). could i use a Scythe Slip Stream Kaze Maru2 140mm Case Fan, (because it can fit in 120mm screw holes)instead of the 120mm fan that comes with it. would it work. i would like to have a opinion if it would work or not before i actually try it.
As long as it fits in your case OK then it will work.
however because you are pushing air through a radiator i suspect that a 140 would end up pushing air around the rad, whilst the 120 would loosely seal to the edges of the rad?
