I had my system in a case running with 6 fans in it (one PCI slot cooler, p/s fan, 2 rear exhaust fans, one front fan, and one big 90mm side fan) and my average temps were around 125 F on full load with the stock HSF. Now, I toolk my mobo and everything else out to clean all of the dust out and wanted to see what the temps would be with out the case. I hooked up all of the ribbon cables, and power lines and now my temps are down to 107 F full load! What a difference! Anyone else do anything like this?
