Replacing the fan
Notice | |
Incorrect fan type The industrial PC may be damaged if the wrong type of fan is installed.
|
Before you can replace the fan and CPU cooler, you must gain access to the interior of the industrial PC (see chapter 7.2.1 Access to device components). You must switch off the industrial PC before you can replace the fan or CPU cooler.
In the basic configuration, there is a 120 x 120 x 25 mm fan behind the front of the industrial PC. Your PC is equipped with three 5¼-inch drive slots in that case. Should you have ordered your PC with six 5¼-inch drive slots, there are two 60 x 60 x 25 mm fans behind the front of the device. The fans are replaced in the same way.
The following table provides information about the assignment of the fan connectors on the motherboard and the respective fan options.
Fan | Connection |
|---|---|
Upper fan 60 x 60 x 25 | FAN1 |
CPU cooler | FAN2/CPU |
Lower fan 60 x 60 x 25 | FAN3 |
Standard fan 120 x 120 x 25 | FAN4 |
