[M] Thermaltake Max 5G Active Cooling 3.5'' External HDD Enclosure Review
 

Inside the Max 5G Active Cooling 3.5'' USB 3.0 External HDD Enclosure from Thermaltake, we can install in a matter of seconds our drive and start transferring data at high speeds. The dual 80mm fans help cooling the HDD while it is on, so we can obtain similar temperatures as we would have installed the drive inside a well ventilated computer case.
