Direct replacement for Lenovo B570 and B575

This new original CPU fan is built for Lenovo B570, B575, B570E, B575E, V570, V570A, Z570 and Z575 laptops. It matches the OEM part number DFS531205HC0T FA9N to restore factory cooling performance. Buyers needing a cooler for other laptop models or desktop sockets cannot use this unit.

Low-profile airflow for slim chassis

The slim blower design fits the tight clearances of the listed notebooks and draws power from the standard 4-pin system header. It spins up under load to move heat away from the CPU die and heat-pipe assembly. No separate power adapter or external controller is required for normal operation.

Questions about this item

How do I install the DFS531205HC0T FA9N cooler on a Lenovo B570, and which step is often missed?

Remove the old cooler, clean the CPU surface, apply fresh thermal paste, then fit the new unit and plug its power cable into the motherboard header; the step often missed is cleaning off the old paste completely.

What maintenance will the DFS531205HC0T FA9N need later, and when should I replace it?

Clean dust from the heatsink and fan blades every six to twelve months; replace the cooler if the fan becomes noisy, stops spinning, or CPU temperatures rise unusually high.
