DBTLAP laptop cooling pad DL80 778102-001 790536-001

Genuine HP Gen9 Replacement Fan

This genuine replacement cooling fan is designed for HP Gen9 laptops using part numbers 778102-001 and 790536-001. It serves owners who need to replace a worn or noisy original cooler. The package includes one tested fan unit ready for installation. Buyers with different laptop models or generic cooling requirements should verify compatibility before purchasing.

Direct Motherboard Connection Limits

The fan connects directly to the laptop motherboard header, so control and monitoring depend entirely on the system firmware. Speed curves and acoustic behaviour are fixed by the original thermal design. Users seeking software fan curves, PWM adjustment or external controller support will not find those options here. The interface provides no additional sensor data beyond standard tachometer feedback.

OEM Part Number Match Decides Fit

Correct fit is determined solely by matching the original equipment part numbers 778102-001 and 790536-001 printed on the existing cooler. Physical dimensions, screw locations and connector pinout must align with the factory assembly. Visual inspection against the original fan is essential because the supplier may ship units from Forcecon, ADDA, Sunon or Kipo depending on stock. No other specification overrides this requirement.
