I disagree. While it is indeed taking heat from radiator into case, it is also sucking cool outside air from front of case THROUGH the radiator (like a car), instead of hot air from inside the case.
The way my stuff is set up, it wouldn't get adequate airflow in the exhaust fan position (as an intake), because its like 4" from the wall. A couple tests ive seen done with the h90 set up as exhaust vs intake show intake at least a couple degrees cooler (corsair also strongly suggests using it as intake for this reason), and this makes perfect sense for the reason I stated above. cool outside air pulling through radiator makes it much more effective than inside hot air.
that, in addition to the gigantic 240mm exhaust fan on top along with the pretty big 140mm rear exhaust fan, I don't think it is introducing too much hot air into the case to be vented.
HAF 932 also has gigantic 240mm intake in front of drive bays and on side panel.
so im positive airflow at this time, which I like better. if I wanted to go negative I would turn side 240 around to exhaust. too many dust bunnies in my house for that lol. In a lesser case without the enormous airflow of the HAF 932, I could see the need for it being an exhaust.
