Haha, that's bullcrap, you did NOT overclock that thing to 2 GHZ, even with watercooling that's impossible due to your RAM and the nature of the P3, and ESPECIALLY the 200 watt PS, I mean, dude, just stop lying.
u also need to rethink ur intake to exhaust ratio with the fans i mean 9:1 and 5:1 cant be working to well for u and u overclocked a p3 a whole ghz with 10 fans (working about the same as 4 with your setup) and a 200w ps? Ur askin 4 trouble
having an actual air conditioner cool your system wouldnt be a good idea anyway, everyone knows that the backside of it procudes a bunch of heat, and that wouldn change the ambient(room) temp and it would prolly be pretty inefficient.
