Replacement CPU fan for Acer Aspire 4740 series

This new DBTLAP cooling fan replaces the original ADDA AD7105HX-GD3 unit in Acer Aspire 4740 and 4740G laptops. It operates at 5V with a 0.18A draw to match the factory power profile. Each unit is tested before shipping to ensure reliable operation.

Upgrade from a failed or noisy original cooler

The jump is worth it when the existing fan rattles, overheats or stops spinning entirely. Verifying the part number against the old component guarantees 100% compatibility before fitting. Photographs of the supplied item help confirm the physical match.

Direct-fit cooler for compatible Acer chassis

The fan handles the thermal load designed for the 4740 platform without modification. It runs out of headroom if the heatsink fins are clogged with dust or the thermal paste has degraded. Buyers needing a different voltage, connector or mounting layout cannot use this part.
