I installed two 80mm Coolmaster fans like this: Code: _______________ |PSU | <- |O | | | | HDD| | O| <- |______________| The O's being the fans. The front fan, under the HDD is blowing air in, and the one under the power supply is blowing air out. When I ran temperature tests, the temperature of my CPU wasn't really that different than normal. (37 C Normal, 50-59 Playing a game) I'm not sure if these temperatures are ok, or if I need to do something about it, or if the fans are even necessary. (I also made the holes bigger in my case's fan cutouts so more air would go through) Any help would be appreciated.
