Laptop coolers are everywhere.  Even Walmart has a few.  However most of the ones I have seen take up a USB port and/or power some noisy fans.  The Thermapak doesn’t take any USB ports and can be rolled up and put in your bag.  The ThermaPak is available in sizes from 13 inches to 17 inches in Black or Pink.  They are also available in a white color that is sized for use with MacBooks.  Pricing ranges from $27.99 to $34.99 depending on the size.  Check out the ThermaPak website for details.
