Room temps around here are about 65 degrees F.
My computer used to run at total stock cooling, the CPU was overheating crazily at stock speeds with AS5. My GPU was idling at around 40 degrees.
I found no reason why I should go with watercooling while my room temperature isn't exactly high. I got a copper heatpipe TOWER from thermaltake, my CPU now idle's at 31C and runs full load at 45. I replaced my GPU used to IDLE at 50C with BFG HSF, after my NV Silencer, my computer is MUCH quieter, and my GPU temperatures lowered about 10 degrees C, of course I also used AS5.
