I've noticed Stock CPU fans tend to point the fan downward and push cool air down onto the heatsink. My side fan, for some reason, was facing outwards. This made the temps go up to 150*F at times. I reversed the fan so it points inwards and noticed even at peak my temps stay around 110*F! It's noticeably louder though because of all the moving air. If this is the case, then why do Case makers put the fans facing outwards?
