iMac 24" A1225 Hard Disk Fan

This replacement fan fits the iMac 24-inch model A1225 and matches part numbers 620-3942, 604-0274, 620-4336, 922-8154, B1206PHV1-A and 13.MS.B3339.F. It is intended for technicians and owners servicing the internal hard-disk cooling assembly. The unit ships new and ready for installation.

Integration into an iMac 24" build

The fan mounts directly onto the hard-disk bracket inside the iMac 24-inch chassis and connects to the existing logic-board header. No additional cables or adapters are required. It restores original airflow to the drive bay, leaving other internal clearances unchanged. Buyers needing a different form-factor fan or a complete logic-board assembly will not be served by this part.
