Several years ago, we would regularly review. Some would use fans, other passive cooling, and most provided a reasonable amount of heat reduction, or at least protection from the dreaded scourge of hot-lap.
Since then, not much new has happened in the world of lapdesks, and our interest waned. NZXT, however, has an interesting new idea that at least got me to fire up a high-end gaming laptop and put the $28 NZXT Cryo E40 to the test.
This understated-looking cooling desk, with a metal top panel and plastic base, containes two 40-millimeter cooling fans, powered via USB. What makes it different is that the fans are not set in a fixed position. Instead each fan has four tiny magnets, one in each corner, attaching the fan to the metal top panel. This allows you to remove that top panel (also held in place magnetically) and reposition the fans as needed.
Depending on where your laptop's fans, hard drives, and graphics hardware are located within the chassis, an external cooling fan could be more useful in some positions than others. Being able to position the fans within the Cryo E40 lets you put them to use where they can do the most good.
