Add bottom fan. Done. I've seen a few case mods for PCs that put in a fan in the bottom. I determined that this might help me, so I did it myself too. Bought this fan today. 110CFM. Also replaced the intake fan, 21CFM. Tomorrow, clean up and attach VGA cooler from donated ATI Radeon 9800 Pro to my own 9800 Radeon Pro. Apparently, the fan on mine was not working and I didn't know it. Got some thermal paste for that today too. Sunday, probably putting it all back together. Bonus: Learned how to jumper an ATX power supply today so that it runs without being attached to a logicboard. Going to hook another 250W PSU up to power just my drives and fans and leave the main PSU to power just the logicboard and cards and devices plugged into same. Eventually, I'll get that ATX PSU but this will work for now. At some point I will actually begin the job of trying to either fix the old OS install or restart fresh.
