Heatsink and fan for ThinkPad T570 and P51S

This replacement cooling assembly fits Lenovo ThinkPad T570 and P51S models equipped with discrete graphics. It serves technicians and owners repairing or maintaining those specific laptops. The part matches FRU numbers 01AY475 and 01AY474 for direct compatibility.

Thermals noise and power in normal use

The heatsink and fan dissipate heat from the CPU and discrete GPU during typical workloads. Fan speed adjusts to thermal demand, so acoustic output varies with system load. Power draw comes from the laptop's motherboard header and stays within the original design envelope. No separate power supply is required.

Questions about this item

How do I install the heatsink and fan assembly in a ThinkPad T570 or P51S with discrete graphics?

Remove the bottom case, disconnect the old fan cable, unscrew the heatsink from the CPU and GPU, clean old thermal material, apply fresh paste, mount the new unit using the original screws, reconnect the fan header, then reassemble.

What maintenance will the heatsink and fan need over time?

Periodically blow dust from the fan blades and fin stack with compressed air; if temperatures rise, remove the assembly, clean the mating surfaces, and reapply thermal compound before refitting.
