New CPU fan for HP G4-2000 G6-2000 G7-2240US G7-2000 G6-2278DX / 683193-001 685477-001 / 4pins Brand new and original

The cooling fan for HP Pavilion G4-2000 and G6-2000 series laptops is an internal CPU thermal fan designed to keep your notebook’s processor and internal components at safe temperatures. As the CPU works — especially during heavier tasks like multitasking, video playback, or light gaming — it produces heat that must be expelled. The fan pulls cool air in and pushes warm air out through vents to maintain stable performance and prevent overheating, loud noises, thermal throttling, or unexpected shutdowns. Over time, dust buildup, worn bearings, or wear and tear can make the original fan noisy or fail entirely. Replacing the fan restores proper airflow and cooling efficiency, helping the laptop run quieter and more reliably.

Replacement fans for this series generally feature a 4-pin PWM connector that plugs directly into the motherboard and allows automatic fan speed control based on temperature. Common compatible HP part numbers used for these fans include 683193-001 and 685477-001, and they may also be listed under internal identifiers like 055417R1S, FAR3300EPA, and KSB06105HB-BH2G — all meant to match the OEM cooling units in the Pavilion G4-2000 and G6-2000 lineup
