Replacement fan for Samsung NF110 NF210 NF310

This 5 V three-pin sleeve-bearing cooler fan matches the KSB0405HA model used in Samsung NF110 NF210 NF310 notebooks. It draws 0.4 A and has no LED lighting. The silver housing fits the original mounting points. Buyers who need a different voltage or a four-pin PWM connector should look elsewhere.

Fits original notebook heatsink assembly

The fan connects directly to the existing three-pin header on the notebook motherboard. No adapter or soldering is required. Its sleeve bearing keeps the profile low for tight chassis clearance. Builders who need a larger desktop heatsink or a liquid-cooling radiator cannot use this part.

Steady airflow at constant 5 V supply

Under continuous load the sleeve bearing maintains consistent rotation at the rated current. Acoustic output remains stable because the voltage does not fluctuate. Users who expect variable-speed curves or high-static-pressure spikes will not find them here.

Questions about this item

How long does the sleeve bearing last under continuous 0.4 A load?

Sleeve bearings typically wear faster than ball bearings under non-stop 0.4 A operation; expect reduced lifespan compared to intermittent use.

How much noise and heat does the 5 V 3-pin fan produce when running all day?

The 5 V fan draws 0.4 A, generating modest heat; sleeve bearings run quieter at low speed but may develop a hum after extended daily use.

Which Samsung notebook models accept the KSB0405HA 3-pin connector?

Direct fit for Samsung NF110, NF210, NF310 and part numbers M-935-11 and BA62-00543D; other laptops need matching 5 V 3-pin header and mounting holes.
