Replacement CPU Cooling Fan for Toshiba Qosmio F50

This new DBTLAP cooling fan is a direct replacement for the original CPU cooler in Toshiba Qosmio F50 and F55 series laptops including the F55-Q502 model. It is intended for owners or repair technicians who need to restore factory cooling performance after a bearing failure or airflow loss. The unit ships as a single tested fan assembly ready for installation.

Electrical Interface Limits

The fan operates on a DC 5V supply drawing 0.40A, so it must connect to the laptop's existing fan header that provides exactly that voltage and current budget. Using a header with a different voltage or insufficient current capacity will prevent the cooler from spinning at its designed speed or cause it to stop entirely. No adapter or voltage converter is included or supported by this part.

Part Number AB7505HX-SB3 Compatibility

The single specification that determines fit is the manufacturer part number AB7505HX-SB3 printed on the original fan label. Only laptops that list this exact part number in their service manual or on the sticker will accept the mounting holes, connector pinout and cable length of this replacement. Buyers who cannot confirm that part number on their existing cooler should not order this fan.
