Great, now all you guys worrying about your hard drives should chill out - there is no need for an extra fan under the hard drive, lots of people are running 7200 rpm drives, with stock systems and not having problems. You're more likely to have a problem from "browning out" the power supply by putting too many accessories (like fans) on it - if youre worried about it, go to your hard drive manufacturers website, and pull the data sheet on your particular hard drive - then check your temps in evox - If your stock fan is working at all, you won't be cooking a drive. If you're worried about it, buy your hard drives in a retail box ( not off pricewatch) - the retail hard drives have a longer warranty than the ones in the white box.
