Compatible Legion 5-15ARH05H Heatsink Fan

This replacement heatsink and cooling fan assembly is built for the Legion 5-15ARH05H and 5P-15ARH05H laptops. It matches part numbers 5H40S20132 and 5H40S20133 for a direct fit. Technicians and owners can use it to restore original cooling performance when the factory unit fails or wears out. It is not suited for other laptop models or desktop builds.

Normal-Use Thermals and Power

In typical operation the fan spins up to move air across the heatsink fins, keeping the CPU within its thermal limits during everyday workloads. Acoustic output stays at a low background level that suits office or home environments. Power draw is minimal, pulling only what the laptop's motherboard allocates for the cooling subsystem. No liquid cooling or external power is involved.

Questions about this item

How is the heatsink and fan assembly installed in the Legion 5-15ARH05H, and which step do people often get wrong?

Remove the bottom cover, disconnect the battery, unplug the old fan cable, unscrew the heatsink, clean the old thermal paste off the CPU and GPU dies, apply fresh paste, mount the new 5H40S20132 assembly, screw it down in a cross pattern, reconnect the fan cable, then reattach the battery and cover.

What maintenance will the 5H40S20133 cooling fan need later?

Blow dust from the heatsink fins and fan blades with compressed air every few months; if the fan becomes noisy or stops spinning, replace the whole 5H40S20133 unit.
