Compatible Dell Vostro models

This replacement cooling fan fits Dell Vostro 3510 3511 3515 3520 3525 and 3420 laptops. It matches part numbers EG50040S1-C026-S9A 0T1NNF 023.100ZW.0021 0A. Buyers who need a fan for a different Dell series or a desktop chassis cannot use this part.

5 V operation and tested reliability

The fan runs on a 5 V supply drawn from the laptop motherboard. Each unit is tested before shipping to confirm it spins freely and moves air through the heatsink. No separate power adapter or controller is required.

Direct swap for the original cooler

The package contains one fan assembly ready to install in the existing mounting points. No additional brackets thermal paste or wiring harnesses are included. Builders who need a complete heatsink module or a dual-fan upgrade should look elsewhere.

Questions about this item

How do I install the DBTLAP cooling fan in a Dell Vostro 3510 and what step is often missed?

Remove the bottom cover, disconnect the old fan cable, match the EG50040S1-C026-S9A part number on the label, then secure the new fan and reconnect the 5V power plug before reassembly.

What maintenance will this Vostro 3520 cooling fan need later?

Clean dust from the fan blades and heatsink fins with compressed air every few months; replace the unit if the bearing becomes noisy or airflow noticeably drops.

What limit appears first on this 5V fan during sustained heavy loads?

The 5V power ceiling limits maximum RPM, so under prolonged 100% CPU load the fan hits its speed cap and cannot increase airflow further.
