Additional details regarding the fans for the R310 include:

The Embedded Server Management logic in the system will control and monitor the speed of the fans. A
fan failure or over-temperature in the system will result in a notification from iDRAC6.

The R310 power supply units do not have any integrated fans; they are cooled by the system fan in front
of them. The system requires a PSU blank (metal cover) in place of the empty power supply slot.

System fan speed is pulse-width modulated.

Fans are non-redundant and not hot-swappable.
