"Great quality fans for heavy graphic gamers."4.5 starson by kormathaw1
Pros: High power fans.
Adjustable fan speed.
Can keep up with cooling the most graphically intense games that other matts can't keep up with.
Cons: Hard plastic so less comfortable than some other mats.
Requires 2 USB ports for the power.
Noisy fans when at full throttle.
Summary: I bought this to replace my Targus AWE55US mat that could not keep up with cooling my Dell laptop on graphic intensive games. While it certainly has its negatives for the casual user, for gamers this mat is a huge step up from its little brother. On games that overheat my computer in 15 minutes, the AWE55US still overheats in 30 min, with the HD3, it doesn't overheat. Enough said.
