Replacement Laptop Cooling Fan BS4505HS-U81

This original new cooling fan is designed for laptops using the BS4505HS-U81 assembly and part number 49R-3A141E-0502. It operates at 5 volts and draws point five amps. The unit suits repair technicians and owners replacing a worn or noisy fan in compatible machines.

Upgrade From Failed Or Loud Stock Fan

The fan replaces the factory-fitted cooler when bearings wear out or airflow drops below spec. Swapping it restores thermal headroom and cuts acoustic noise without modifying the chassis. Buyers needing a different voltage, connector layout or higher airflow should verify specifications before ordering.

Questions about this item

Will the BS4505HS-U81 49R-3A141E-0502 fan fit my laptop's existing mounting holes and connector?

This fan is built to the BS4505HS-U81 49R-3A141E-0502 specification. Match that exact part number to your service manual to confirm the screw pattern and plug orientation before ordering.

What is the correct way to connect the 5V 0.5A power lead during installation?

Align the connector key with the motherboard header and press straight in until seated. The common mistake is forcing the plug in reversed, which bends pins and prevents the fan from spinning.
