Replacement fan for Dell N5110

This 40 mm cooling fan is built as a direct replacement for the Dell N5110 laptop. It runs on 12 V power through a 4-pin connector and uses a double ball bearing for durability. The unit is new and carries CE certification.

Suits owners needing an exact match

Buyers repairing a Dell N5110 with part numbers 0C96VF, C96VF, EG50060S1-C390-S9A, DFS200005940T, FL8X, DC28000NZF0 or DC28000NZS0 will find the correct fit. Anyone whose laptop uses a different connector, voltage or mounting pattern should look elsewhere.

PWM control and speed monitoring included

The 4-wire interface adds PWM intelligent temperature control and a speed measurement signal so the system can regulate fan speed automatically. A plastic frame keeps weight low while the bearing is rated for 70000 hours of operation.

Questions about this item

What laptop model must I already own for this 40 mm 12 V DBTB0428B2G fan to fit?

It is built for the Dell N5110 and matches part numbers 0C96VF, C96VF, EG50060S1-C390-S9A, DFS200005940T, FL8X, DC28000NZF0 and DC28000NZS0.

Will the 4-pin PWM connector on this replacement fan work with the original motherboard header in my N5110?

Yes, the 4-wire interface carries the same PWM intelligent temperature control and speed-measurement signals the original fan used.

How can I verify the fan is running at its rated 18000 RPM after I install it?

The 4-pin header reports real-time speed to the system; you can read the RPM in BIOS or a hardware-monitoring utility and confirm it sits near 18000 RPM ±10 %.
