How much cooler does your unit run? I've been thinking of trying one when I use my laptop to do CPU intensive video compiling and conversions that can run for many hours.
It might be worth the price if it will knock of ten degrees.
I've had it running for hours and the computer is BARELY warm. And thats with the fan on low. It also has a high setting.
This is a GREAT tool!
BTW, Staples originally sells them for around 40 bucks but I got it yesterday for 16.
