The Intel® Server Chassis SC5300LX contains two 120 mm and two 92 mm hot-swap fans.

Although the fans can increase RPM by 10 percent, that might not be enough to adequately cool the system in some environments.
The Intel® Management Module is recommended for SC5300LX redundant cooling. The Management Module has the sensor controls needed to increase fan RPM to the correct levels.
