Unlike the Cooler Master Notepal U1, which is built for smaller laptops up to about 14 inches, the NotePal U2 can hold a larger laptop up to 17 inches in size. However, if you have a really large notebook in the desktop replacement segment, the U3 is most likely a better choice. This is the middle-of-the-road alternative, great for 15- and 16-inch laptops. And as you might have guessed, the number next to the ‘U’ stands for the amount of fans the cooler is equipped with.
In other words, this one comes with two fans that operate through an aluminum mesh to provides ample cooling for any machine you place on it. The two 80mm fans are actually removable in case you just want to use it as a stand. The most attractive part of the Notepal U2 is its combination of excellent cooling performance and a very low price point. There are few cooling solutions on the market that offers this much value without adding the aspect of being essentially useless.
