4.9 Fans
Two or four 92 mm single-rotor fans are mounted in the back of the cooling shroud. Each fan has a
single-wire harness that plugs into the planar fan connectors (FAN1 through FAN4). In a non-
redundant configuration, two fans must be installed towards the back of the chassis.
The iDRAC6 controls and monitors the speed of the fans. A fan speed fault or over-temperature
condition results in a notification by iDRAC6.
The T610 power supply units have integrated fans. They are cooled by fans in the front section. The
system requires a blank module in place of the empty power supply slot.
All system fans are pulse-width modulated (PWM) fans. Redundant cooling (optional) is supported.
