MAXX 1200HD/2470HD CPU FAN REPLACEMENT
Caution – Use standard electrical safety and ESD procedures at all times.
*Note that when replacing a CPU fan in the field, to avoid having to remove the motherboard from the chassis, the fan legs must be trimmed to avoid bottoming out on the chassis, which prevents proper installation. CPU fan replacements purchased from 360 Systems will already be properly trimmed. Replacement fans sourced elsewhere will need to be modified as shown. Trim legs in the locked position, then unlock to install. To lock, push the white and black parts together until they lock. To unlock, rotate the black part in the direction of the arrow, then pull up on it until it pops out, then rotate it back to the initial position so it will lock again during installation.
Before Trimming After Trimming
