Replacement fan for Dell Studio XPS 1640 1645 1647
This replacement CPU cooler fits Dell Studio XPS models 1640, 1645 and 1647 as well as the W520D chassis. It is a direct swap for the original Forcecon, ADDA, Sunon or Kipo unit referenced by part numbers DFS541305LH0T, GB0508PGV1-A and B3679.13.V1.F.GN. The fan runs on 5 V and draws 0.33 A. Each unit is tested before dispatch.
Airflow limit of the 8 CFM design
The cooler moves 8 CFM of air, which is the factory-rated airflow for the original thermal solution. That figure caps the heat the fan can shift, so systems running sustained heavy loads may still throttle if the heatsink or vents are clogged. The 5 V 0.33 A power budget also means the fan cannot spin faster without a different controller. No higher-airflow alternative is offered in this listing.
Simple swap with connector care
Installation requires opening the laptop chassis, removing the old fan and plugging in the new one using the existing header. The most common issue is a fragile flex cable or a keyed connector that seats only one way; forcing it bends pins. Verify the part number on your current fan against the listed codes before ordering. The package contains one fan only.

Questions about this item
How do I confirm this fan fits my Dell Studio XPS model?
Match the part numbers on your original fan — DFS541305LH0T, GB0508PGV1-A or B3679.13.V1.F.GN — and verify the 5 V, 0.33 A rating before ordering.
What does the 8 CFM airflow rating mean for my laptop?
It indicates the volume of air the fan moves each minute; in a Dell Studio XPS 1640, 1645 or 1647 chassis this airflow is designed to keep the CPU within thermal limits under normal loads.
What power connector standard does this fan use?
The fan runs on a 5 V, 0.33 A supply using the proprietary connector fitted to Dell Studio XPS 1640, 1645 and 1647 motherboards.
