I'm not sure this is the right forum, but it is a cooling problem.

I've got a WHS box with 14 drives (19TB) that is basically loud as hell. I've got a perfect place for it where I don't have to hear it, but it's getting a little warm there. Not to the point of overheating, but warm.

It's in a closet with no A/C vents. Only a door to the closet.

It's heating the ambient room temp to about 85'F. The discs are running between 43C and 47C.

So far in an attempt to cool it, I've taken some aluminum foil ducting and attached it to the back of the box over an exhaust fan and passed the other end out under the door. This does help a little bit, but I'm looking to do a little more.

Any other ideas for moving heat out of this closet? No holes in the door, no leaving the door open (have to keep the wife happy). I think the best thing is moving air under the door, but I'm not sure of the best way. If I can't find a cooling solution, i'm going to have to put this loud monster back near my desk which I don't really want to do.

Thanks in advance!

Yeah, 85F is a bit warm in there. Especially since it's December. Even Houston has a winter...

Here's what I did to cool my, ah, data center (which comprises, at that time, a WHS, a Smoothwall, two full-time Linux FaH rigs, and a well-spec'ed Media Center - all in the laundry room, on shelves under the basement stairs (even in the basement, that room started to get quite warm)):
Bathroom exhaust fan. Simple, and cheap. I simply mounted the fan high in the "data center", and ducted its exhaust lower in the wall (wanted to hide it a little...) It lowered the temps in there back to the basement's ambient temp (in other words, a good 10 degree drop.)

I'd imagine that mounting a bathroom fan in there wouldn't be too much of an issue; can you duct it out of the closet to someplace that's WAF friendly? If you can find a place to dump the air to, you're golden. It'll pull air in from wherever it can get it (like, thru the gaps around the door.)
