Replacement Blower Fan for Specific Notebooks

This new DBTLAP cooling fan is a direct replacement part for notebooks using the FCN FLCB DFS5K121154915 HQ23300020000 assembly. It arrives as a single 4-wire blower unit tested before shipping. Buyers must verify the part number against their original fan to guarantee a correct fit.

Thermals Noise and Power in Normal Use

The 4-wire connector allows the notebook's controller to regulate fan speed based on thermal demand. This enables quieter operation at low loads and increased airflow when components run hot. Power draw follows the host system's fan header specification without needing an external supply.

Critical Compatibility Constraint

This cooler fits only the exact FCN FLCB DFS5K121154915 HQ23300020000 part number. It will not work for buyers who need a different connector pin-out, a different mounting layout, or a universal clip-on pad. Compare the product photos with the original hardware before ordering.

Questions about this item

How do I install the 4-wire blower fan and which step is commonly missed?

Disconnect power, remove the old fan, match the 4-wire connector to the motherboard header, and secure the screws; the step often missed is verifying the part number 121154915 against the original before fitting.

What maintenance or replacement will this cooling fan need over time?

The fan bearings may wear after extended use; expect to replace the unit when airflow drops or noise increases, using the same part number 23300020000 for a direct swap.

What limit appears first when the blower runs continuously under load?

Thermal throttling of the laptop chassis typically occurs before the fan reaches its maximum rated speed, so sustained cooling depends on the system’s own heat dissipation.
