☑️ Key Features

☑️ Complete thermal solution – fan and heatsink are pre-assembled for quick replacement
☑️ 4-wire PWM fan supports variable speed control for better acoustics and cooling
☑️ OEM-style copper heatpipe and base plate for efficient heat transfer from the CPU
☑️ Direct-fit for many Pavilion x360 15-CR / 15-CR / 15t-CR systems with no modifications required
☑️ Ideal fix for overheating, loud bearing noise, or fan failure in 15-CR series notebooks

⚙️ Fit Notes

• Match the part number on your original module (L20818-001 or one of the interchangeable numbers) and compare the heatsink shape and screw locations to the photos before ordering.
• This assembly is intended for the standard single-fan CPU cooling configuration; systems with dedicated GPU or dual-fan designs may require a different heatsink.
• Always disconnect power and battery before service. When installing the new heatsink, clean the old thermal compound from CPU contact surfaces and apply a thin, even layer of high-quality thermal paste such as Shin-Etsu G751 thermal paste for optimal cooling performance.
