Lenovo ThinkSystem FAN Option Kit

The SR630 server supports up to seven hot-swap system fans that provide N+1 cooling redundancy. SR630 server models with one processor include five system fans, and server models with two processors include seven system fans. The fans are dual-rotor counter-rotating units, which means that the fans have two separate propellors, one in front of the other, and that the propellors rotate in opposite directions.

In the case of a system fan failure, performance might be impacted if any of the following processors are installed:

- 2nd Gen processors with 200 W or 205 W TDP, or Xeon 6240Y, 6244, 6246, or 6252N processors
- 1st Gen processors Xeon 6144, 6146, 6154, 8168, 8180, and 8180M

The installation of a 2nd processor requires an extra cooling fan be installed. For CTO orders, fans are derived by the configurator. For field upgrades, 1st Gen processor option part numbers include this fan however 2nd Gen processor options do not included the fan and it must be ordered separately using SR630 Fan Option Kit
