Compatible Dell Vostro models

This replacement cooling fan fits Dell Vostro 3510 3520 3525 3511 3420 and 3515 laptops. It matches part numbers 0T1NNF BN7505S5H-007P and 023.100ZW.0001. The unit operates at 5V and is intended for owners who need a direct swap for a worn or noisy original fan.

Sustained thermal performance

Each fan is tested before shipping to verify it spins up and moves air under continuous load. The 5V motor maintains steady airflow during long sessions without the speed drops that can appear in untested units. Buyers who need higher airflow than the original design provides should look for a more powerful cooling solution.

Pre-order verification steps

Compare the photos in the listing with the fan currently in your laptop to confirm the connector layout and mounting holes match. Check the part number on your existing cooler against 0T1NNF BN7505S5H-007P and 023.100ZW.0001. If the numbers or the physical appearance differ, this fan will not fit your machine.
