Title: Fan review; Thermaltake Mobile Fan II External USB Cooling Fan
Review: I bought this little fan to cool an HD-DVR and Amplifier, both of which get very warm when in operation. My cabinet has glass doors which I had to open when in use so as not to overheat the equipment. I cut a small square opening in the back of my entertainment cabinet just large enough to wedge this little unit in. I cut a few other ventilation slots along the bottom of the rear cabinet and connected the USB cord to an open slot on the DVR. The fan has an adjustment for how fast the blades circulate air. Even at half speed, the unit kept both devices cool with the doors closed. Its a pretty quite fan, but at full crank is fairly noticeable which is why I keep it running at half speed.
Is the review positive or negative?
