Ultra-quiet 70 mm cooling fan.
By default the fan is not activated under normal temperature conditions.
The following criteria depicts the system fan behavior dependend on the
internal hard disks temperature:
up to 54 °C: fan is off
55~59 °C: fan rotates at low speed
60~61 °C: fan rotates at middle speed
62 °C and above: system shuts down
The System also shuts down when the system temperature exceeds 65 °C. [2] - Accessories

Remarks:
[1] depending on the test environment
[2] the threshold temperatures are subject to change by firmware update.
The KD20's threshold temperature refers to the "Current internal temperature" provided by the SMART monitoring system. This temperature may be much higher than the "operating/ambient temperature" that is also mentioned in the hard disk specification. The KD20 only supports hard disks with SMART monitoring system and temperature sensor which all available SATA hard disks should support.
