I have already posted this under air cooling but got no response, so I decided to try my luck here,.
I have had this computer for 2-3 years now and just noticed that my cpu cooler is blowing air into the case. Can I just take out the mobo and turn the fan around so it pulls air from the heatsink instead of pushing it or do I have to turn the entire heatsink around and if so, do I need a new application of thermal paste?
