Replacement fan for Lenovo Z470 series

This OEM Industries cooler is a direct-replacement fan assembly built for Lenovo Z470, Z470A, Z470G, Z470K and Z475 laptops. It operates at 5 V DC and draws 2.5 W through a standard four-pin connector. The maglev bearing reduces friction for quieter, longer-lasting operation. No LED lighting is included.

4-pin 5 V power connector

The four-pin interface is the single specification that determines fit; it must match the motherboard header on the listed Lenovo models. Voltage is fixed at 5 V DC and power draw at 2.5 W, so the board must supply exactly that rail. Maglev bearing type is factory-fitted and not user-serviceable.

Suits owners repairing listed Lenovo laptops

Technicians replacing a failed or noisy CPU fan in a Z470, Z470A, Z470G, Z470K or Z475 will find the correct connector and voltage here. Builders assembling a custom desktop, users needing a PWM-controlled case fan, or anyone whose machine uses a different pin count or voltage should look at other parts.

Perguntas sobre este artigo

What does the 2.5W power draw mean for my Lenovo Z470 cooling?

The fan consumes 2.5 watts at 5V, matching the original specification so the laptop's fan header can drive it without extra power.

How does the 4-pin connector affect speed control on a Z470?

The 4-pin PWM connector lets the motherboard vary fan speed automatically based on CPU temperature.

Will this fan fit the mounting holes on a Lenovo Z475?

It is listed as a direct replacement for the Z475, so the screw pattern and dimensions match the original cooler.
