When in doubt, simply go big. That is certainly what Thermaltake has done with its Massive23 LX notebook cooler. Supporting laptops ranging from netbook dimensions all the way up to 17 inches, the Massive23 LX features a whopping 230mm fan (much like the ones that have cropped up in a number of case designs and the previous Massive23 ST), with a rated voltage range of 4-5V and a speed of 600RPM (plus or minus 10%, so 540-660RPM). The fan can be turned on or off via the provided switch, while another switch controls the fan's blue LEDs. Thermaltake also aims to provide an ergonomic typing angle with the design and includes rubber feet, both top and bottom, to prevent your laptop or the cooler slipping. You also get carrying handles and two USB 2.0 ports thrown in (the fan itself is also USB powered). Weighing in at 900g and with dimensions of 376 x 300 x 51.5mm, the Massive23 LX comes with an MSRP of $19.99.
