Hmmm, Ok. Anyone else have thoughts on this?
I was being sarcastic sorry
airflow plays a big part in cases, its highly suggested that cold air goes in from the front/bottom and out through the back/top (heat always goes up, that's why hot air balloons go up) so having all the fans exhaust isn't bad at all but its less efficient. If you have exhaust on the bottom, its gonna defeat the purpose of heat dispersion and having it in the front will heat up HDD, CD players, and other frontal devices (But u made urself one expensive heater)
TL;DR: Having all exhaust fans is ok but not efficient at all, and NOT recommended for Over Clockers
