Today, I just bought a Targus chill mat for mac for under 30 bucks. When I tested it out, It did not give me the results I expected. I taught that I would get a couple of degrees lower in temperature. I'm planning on taking it back to the store. On the other hand, I was looking into this cooling mat: http://www.geardiary.com/2007/05/06/thermaltake-ixoft-fanless-notebook-cooler-review/ It looks kind of promising, but I need anyone's opinion. What is the best cooling pad/mat that can fit under my $30 budget? I'll appreciate anyone's comments, thanks.
