At first glance, it may seem that if you've seen one laptop cooling stand, you've seen them all. That's not entirely true, although there are plenty of similar models, usually in the form of a fixed plastic wedge, either with or without USB-powered fans.
Aftera few years ago, since not much interesting has happened in that space, I haven't felt the need to revisit the topic. But every once in a while a laptop stand does something a little different, and is worth a fresh look.
Recently, NZXT got creative, adding movable fans to its, making it easy to adjust the airflow. Targus has a different hook, but still an interesting one, in the Space Saving Lap Chill Mat, a $42 (I've seen it for $29 at online retailers) folding stand that incorporates dual fans.
That means the Targus stand folds down nearly flat, measuring only 1.25 inches thick in its closed state. Twist a knob to open it, and the back edge pops up, creating a wedge shape that raises the back edge of your laptop 2.5 inches from the desk. That may not sound like a lot, but it's a sizable lift, as seen in the photos here. This wedge shape allows for better airflow and cooling, and also can create a more ergonomic angle, depending on the height of your chair and desk.
