Can i know whether Acer's Desktop's cooling system are good? Or is it bad and needs a aftermarket replacement over it? I'm using Acer Aspire E500 with Pentium D 830, and the design of its cooling are 'well positioned' with the casing it self, sort of giving it a air supple duct with a air duct connecting through a opening on the case cover, right now experienced no overheating or whatsoever but just to b sure, are Acer's Desktop's cooling system good or bad? anyone has review or good/bad experience with these OEM coolers?

they are good 4 stock speed.. Take note to clean em periodically...
