Replacement fan for FLDH DFS5K121144645

This DBTLAP cooling fan is a direct replacement part for the FLDH DFS5K121144645 laptop model. It is intended for owners of that specific device who need to replace a worn or faulty original CPU fan. The unit operates on a 5V power supply drawn from the laptop's motherboard header.

Limited to exact model match

The fan is designed solely for the FLDH DFS5K121144645 part number and will not fit other laptops, even from the same brand. Physical mounting points, connector pinout and airflow direction are fixed to that chassis. Buyers must verify the part number on their existing fan before ordering to avoid incompatibility.

Part number 121144645 confirms fit

The critical specification is the manufacturer part number 121144645 printed on the original fan label. Only an exact match guarantees correct voltage, connector orientation and screw-hole alignment. If your current fan shows a different number, this unit will not install correctly.
