After having used a handful of notebook coolers that use rigid bodies with
fans to get the job done, the iXoft is obviously the quietest, easiest to setup,
most portable, and still quite effective. The somewhat mysterious and scientific
nature of Thermaltake's heatshift technology makes the iXoft even more appealing, as
it is just that much different than the typical cooler.
