-
Insert the fan module on the inner side on the rear cover, for this purpose push the bent slot bracket onto the rear cover. Fasten the fan with the screws removed before.
-
Insert the plug of the fan power supply cable into the appropriate plugs on the motherboard, see picture below.

The guide pins on the plug ensure a proper position of the connection.
