Notebook CPU fan for Lenovo S-series

The OEM Industries BASA5508R5H is a 5 V 0.4 A hydraulic-bearing blower with a four-pin power connector. It is built as a direct replacement cooler for Lenovo S300, S500, S700 and S756 notebooks as well as the A4980 IBM platform. The unit ships new and ready for installation.

Fits specific Lenovo models only

This cooler suits owners of the listed Lenovo S-series laptops or the A4980 IBM system who need a drop-in fan assembly. It does not suit builders working on other notebook brands, desktop sockets or custom liquid-cooling loops that require a different mounting pattern or voltage.

Four-pin 5 V power connector

The single specification that decides fitment is the four-pin 5 V 0.4 A power interface. If the original cooler uses a different pin count, voltage or current rating, this unit will not connect or operate correctly.

Questions sur cet article

How do I install the BASA5508R5H fan and which step is often missed?

Align the four-pin connector with the motherboard header, secure the mounting screws in a cross pattern, then route the cable clear of the heatsink fins so it cannot foul the blades.

What maintenance will the hydraulic bearing need later?

The hydraulic bearing is sealed and not user-serviceable; when noise or vibration appears after extended use, replace the entire fan unit.

What limit appears first during sustained load on this 5 V 0.4 A blower?

The fixed 5 V 0.4 A power budget caps maximum airflow, so thermal headroom runs out before the hydraulic bearing wears.
