Please don't hate me for posting a new thread. There was an old thread about cooling the HR20 but it was locked. 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.
