Cooling external hard drive with USB powered fan
Posted 15 March 2010 - 07:14 PM
I think this will work but I am the worlds biggest chicken when it comes to trying stuff on my own.
I am purchasing a fanless external hard drive to use with direcTV. The only con in the reviews was that it ran hot. I would like to buy a USB powered 2 fan laptop cooling unit. Can I power this with the USB port on the HR20? How should I place the fans relative to the HD for the best effect? Is there a better solution than this? I do not want to buy a fan cooled HD case and exchange the guts.
Hopefully this post will fade to page 2 in a day or so.
I appreciate your help. Thank you.

Since you have an HR20, I would just sit the drive on top of it (if possible) and set the entire unit on the laptop cooler. The HR20 gets hotter than the external drive . That would cool both of them.
Check the Deca thread though, I think there is one unit that does not provide power to the USB port, but I cant remember which one it is.

I used a 12V wall wart that I had laying around for power.Just wired the red and black leads on the fan to the wall wart's 2 leads and plugged it in.That way I don't stress the usb outlet on anything.Just make sure the fan blows in the right direction(or reverse the leads).
I tried laptop coolers and found them to not move much air.
