Thermaltake SilverRiver Portable 3.5" HDD Enclosure
Cooling the drive is a quiet, low-profile 80mm fan turning at 1500rpm, promising excellent cooling for today's fast but hot 7200rpm IDE drives. Heated air is exhausted through two grills front & rear. Even located within arm's reach, the fan is almost inaudible, though disk noise can be heard during access. However, the volume is no greater than that emanating from a sealed computer case. While not a silent device, most users will appreciate the SilverRiver's low noise qualities.
