Newegg offers the Cooler Master NotePal Laptop Cooler, model no. R9-NBC-CMC3-GP, for $15. This $15 mail-in rebate cuts it to $0. With $4.99 for shipping, that's the lowest total price we could find by $15, although we saw it for $3 less in September. It's designed for notebooks of 15" or less and features a USB extender and 200mm fan. Rebate expires May 5.
