Air Flow Cooling System (AFCS) AFCS accelerates the circulation inside the drive and speeds up the heat elimination through the drive's steel housing. Anti-Dust Cooling System (ADCS) With an integrated heat chimney design, ADCS redirects the heat flow out of the drive, while still providing protection from dust.
