Replacement fan for FN35 laptops

This DBTLAP cooling fan replaces the original unit in FN35 series laptops. It operates on 5 V DC power and draws 0.5 A. The package contains a single fan that has been tested before shipping. Buyers should verify the part number against their existing fan before ordering.

Direct 5 V DC power constraint

The fan connects directly to a 5 V DC header and is limited to a 0.5 A current draw. No voltage regulation or speed-control circuitry is included, so the host laptop must supply a stable 5 V rail. Systems that require PWM control or a different voltage cannot use this part without modification.

Upgrades a worn or failed FN35 fan

This part restores cooling performance when the original FN35 fan becomes noisy, slows down or stops spinning. The jump is worth it when the laptop throttles under load or shuts down from overheating. It is not for users who need additional airflow beyond the stock design or who want a complete cooling-pad assembly.

Questions about this item

Which FN35 fan revision should I pick for my laptop?

The listing shows a single FN35 revision rated DC 5V 0.5A with part number DFS5K121142629; match that exact code to the label on your original fan.

What does the 0.5A rating mean once the fan is installed?

It draws 0.5 amps at 5 volts, so the laptop’s USB or fan header must supply at least that current for the fan to spin at full speed.

What interface does the FN35 fan use and what does it limit?

The fan connects via the laptop’s proprietary fan header; the 5V 0.5A spec caps the maximum power the header can deliver to this cooler.
