I want to buy this BitFenix Spectre PRO 230mm Fan. I've not installed fans before but I have read that the part of the fan with the "plastic structure" is the back / the "unobstructed" blades is the front.
I'm planning to get a 230mm intake and a 160mm exhaust. Is that good or should I match both fans, i.e, two 160mm fans as intake and exhaust / get a larger exhaust fan than intake? What is the rule of thumb if that makes sense?
