Replacement Fan for FSU3 and FSU1 Laptops

This 5V 0.8A cooling fan replaces the original unit in compatible FSU3 and FSU1 series laptops. It matches the DCS5K121142622 and DFS5L22H15B852 part numbers listed by the manufacturer. The pack includes two fans so both intake and exhaust positions can be refreshed at once. Buyers who need a different voltage or connector layout cannot use this part.

Upgrade from a Worn or Noisy Original Fan

The jump is worth it when the original fan spins loudly, rattles or stops spinning under load. A fresh unit restores the designed airflow without changing the thermal solution. If the laptop still overheats after the swap the limitation lies elsewhere such as dried thermal paste or blocked vents. This fan does not increase the maximum cooling capacity beyond the original specification.

Straightforward Swap with Connector Care

Installation requires opening the laptop chassis and disconnecting the old fan header before fitting the new units. The most common issue is ordering the wrong part number so verify the codes on your existing fan against the list above. Forcing a mismatched connector can damage the motherboard header. If you are unsure about disassembly seek professional assistance.

Questions about this item

Which laptop models does this FSU3 DCS5K121142622 fan fit?

This fan is listed for FSU3, FSU1, DCS5K121142622, 6033B0143301, DFS5L22H15B852 and 6033B0143601 part numbers. Match your original fan to the photos before ordering.

How do I install the two fans and what step is often missed?

Replace the old fans one at a time, matching the connector orientation exactly. The step often missed is verifying the cable routing so it does not catch on the heatsink screws.

When will these 5V 0.8A fans need replacement again?

Expect several years of normal use. Replace them when bearing noise appears or airflow drops noticeably. Keep the laptop vents clean to extend fan life.
