Replacement Fan for HP HSN Q27C

This DBTLAP cooling fan is a direct replacement for the HP HSN Q27C radiator assembly. It operates on a DC 5V 4-pin connection and carries part number EG50050S1-CG90-S9A. The unit is sold new and includes a single fan that has been tested before shipping. Buyers needing to restore cooling performance on a compatible HP laptop will find this matches the original specification.

Upgrading from a failed or noisy original

The jump is worth it when the existing fan has stopped spinning, runs loudly or no longer moves enough air to keep temperatures in check. A fresh, tested unit restores the designed airflow without modifying the laptop. If the current cooler still runs quietly and maintains safe thermals, replacement is not necessary.

Verify the exact part number before ordering

Check the photos supplied and compare them with the fan currently installed in your machine. The part number EG50050S1-CG90-S9A must match exactly; similar-looking fans with different connectors or mounting points will not fit. If you are uncertain, provide your laptop model number so compatibility can be confirmed before purchase.

Questions about this item

What laptop models does the HP HSN Q27C radiator EG50050S1-CG90-S9A fit?

This cooler is built for laptops using the HP HSN Q27C radiator with part number EG50050S1-CG90-S9A; match that number to your service manual before ordering.

How do I install the DC 5V 4-pin fan, and what step is often missed?

Disconnect power, remove the old fan from the heatsink, connect the 4-pin plug to the motherboard header, then secure the screws — the step often missed is re-seating the thermal interface between heatsink and CPU.

When will the DBTLAP cooling fan need replacement?

Replace the fan if bearing noise appears, airflow drops, or the 4-pin connector fails; each unit is tested before shipping, but mechanical wear depends on workload and dust buildup.
