what do you guys do to keep your hard drives cool? reason is, i have wd 120gb ide drive running roughly around 35*C. but my wd 2500k 16mb sata drive is running 50*C and more at times!!! would connecting it to a molex connector opposed to the sata power connector do any difference? oh and these hd's are in a qpack with the sata drive being closer to the side of the case.
