I bought a couple of weeks ago this ext. hdd case (abit different you can see by the pictures), and i put a wd 320GB inside (this one in it). While backing up info I realized the the case gets pretty hot (especially in this country at summer). So i decided to improvise and make a cooling device... first i started off with a plate of painted fiber-glass (the person who painted it for me.. painted it with a .... tongue dispenser, that's why it looks so badly done) i got a couple 12 cm fans like these: next, i stuck the fans on the fiberglass and soldered a PL insert (for power) and a switch.. so this is what it looked like. I also stuck a bit of black sponge on the side that i stuck the fans (so that when i put the unit on the enclosure it won't bang it in anyway): I cleaned it up, and made it tidy, looks like this: next, i put some black sponge on top (making it more aesthetic and nice ) looks like this: connected, and running looks like this unfortunately i can't measure temp before and after, but i can say that if i touched the box it was pretty hot, and now it isn't hot at all. next step (when i get back to Australia) will be to solder the connections straight to the button of the enclosure ... anyway, beside that.. any thoughts?
