Replacement CPU Cooling Fan for Samsung NP300V3A

This new DBTLAP cooling fan replaces the original CPU cooler in compatible Samsung laptops. It is intended for owners of NP300V3A, NP305V3A, or NP355V3A models who need a direct swap for a worn or noisy unit. The package includes one fan that has been tested before shipping. Verify the part number against your old component before ordering.

Thermals Noise and Power Draw

The fan operates at 5V and draws 0.4A to move air across the heatsink. Normal use keeps the processor within thermal limits without adding noticeable acoustic load. Each unit is tested to confirm it spins freely and delivers the expected airflow. No additional power adapter or control software is required.

Critical Compatibility Check

The single specification that decides fit is the manufacturer part number BC46 KSB06105HA BA81-14323B. Only laptops listing this exact code will accept the fan without modification. Buyers who need a different part number or a complete cooling assembly with heatsink should not purchase this item.

Questions about this item

How do I install the KSB06105HA fan in my NP300V3A and what step do people miss?

Remove the old fan, match the connector to the motherboard header, secure the screws, then verify the new fan spins at boot — skipping the spin check is the common error.

What maintenance or replacement will the BC46 fan need later?

Dust the blades and vents every few months; if bearing noise returns or RPM drops, replace the whole fan unit — no separate parts are serviceable.

What limit appears first on the 5V 0.4A fan under sustained load?

The 0.4A current ceiling caps maximum RPM, so prolonged heavy thermals hit the fan’s airflow limit before the voltage rail does.
