Compatible HP Pavilion g7 Models

This 4-pin CPU cooling fan is built for HP Pavilion g7-2286nr, g7-2287nr, g7-2288nr, g7-2289wm, g7-2291nr, g7-2292nr, g7-2293nr, g7-2294nr and g7-2295nr laptops. It serves as a direct replacement for the original processor fan in those specific notebooks. Buyers needing a cooler for a different HP series or a desktop chassis cannot use this part.

Verify Connector and Model Before Ordering

Confirm that your existing CPU fan uses a 4-pin power connector and that your laptop model number matches the supported list exactly. The supplier notes that multiple factories produce these fans so the label on your current unit may differ from the replacement. Contact the seller for a compatibility check if the power specifications on your original fan do not appear identical.

Thermal Operation in Normal Use

The fan draws power through its 4-pin header to spin the blower that exhausts heat from the CPU heatsink. Under typical workloads it maintains processor temperatures within the laptop's designed thermal envelope. Acoustic output remains consistent with the original factory cooling solution and no additional power draw beyond the motherboard header rating is introduced.

Questions about this item

Does the package include anything besides the 4-pin CPU cooling fan for the HP Pavilion g7-2286nr series?

The package contains one CPU cooling fan only; no screws, thermal paste, cables or tools are supplied.

My HP Pavilion g7-2291nr uses a 4-pin connector — will this fan match the power specification?

The fan is built for the listed g7 models including the 2291nr and uses a 4-pin connector; verify the original fan's voltage and amperage before fitting.

What does the 4-pin connector actually control once the fan is installed in the laptop?

The fourth pin carries a PWM signal so the motherboard can vary fan speed dynamically based on CPU temperature.
