7 Notebook Coolers Compared and Tested
 

With the majority of PC shipments being laptops it is time to find out how you can effectively keep them running cool. In this comparison review we test seven different notebook coolers from Zalman, Vantec, Spire, Sunbeamtech, Revoltec and Antec.

Good comparison, but, for me, it left out one important test: How do the coolers behave when used *on* a lap. Are they even *usable* in that sense.

Some of us still use our laptops (even the aircraft carriers) on our laps.

check the bottom of each cooler to see how it's formed. I think of the ones in the review only the Antec is flat enough at the bottom to be used on your lap. The others are either too small, or made to be used on a desk

The Antec cooler should be avoided, I tried one. As you said, it is to small for 17" laptops. Additionally one of the fans wore out after exactly 1 year, makes an insane racket to try and use it. Still under the 3 year warranty, assuming you kept the original purchase receipt which I didn't. I wouldn't want to even pay shipping to warranty it anyway, not worth it in my opinion.
