Query: Pure piece of garbage.

Avoid this thing like the plague. I got one and it worked great; it kept my hard drive cool and I loved it for about 3 months, before it failed. I replaced it from Antec with a RMA, the jerks never told me it'd be on back order, so it took a couple *months* to get it replaced. In the mean time I purchased one from Amazon, defective, and purchased two from Circuit City, both defective. Then Antec sends me back the RMA and IT WAS DEFECTIVE! So out of 5 units, one worked for a few months. Not a stellar track record.
