Replacement CPU Fan for Dell Precision M4400

The DBTLAP cooling fan is a direct replacement for the Dell Precision M4400 laptop. It matches part numbers C449K and MG75120V1-Q000-S99. Each unit is tested before shipping to confirm 100 per cent operation. The package includes one fan ready for installation.

Upgrading from a Worn or Failed Original Fan

This part replaces the factory cooler when it becomes noisy, spins irregularly or stops completely. The jump is worth it when the laptop overheats or shuts down under load. Installing a tested replacement restores the intended thermal performance without modifying the chassis.

For Owners of a Dell Precision M4400 Needing

Buyers who can match the part numbers to their original hardware will find a compatible fit. Those with different Dell models or other laptop brands should look elsewhere, as the mounting and connector are specific to the M4400 series.

Questions about this item

Does the C449K fan mount directly to the Dell Precision M4400 heatsink?

Yes, the C449K is built as a direct replacement for the original Dell Precision M4400 CPU fan and uses the same mounting points on the heatsink assembly.

What is the installation step people often miss when fitting the MG75120V1-Q000-S99?

After securing the fan screws, the cable connector must be fully seated into the motherboard header; a loose plug will stop the fan spinning even though the hardware is fitted.

When should the replacement fan be inspected or swapped again?

The supplier tests every unit before dispatch and backs it with a 9‑month warranty; plan to check airflow and noise at that point and replace if bearings become audible.
