Replacement CPU fan for HP 4530S 6460B 8460P 8470P

This Lemincrash KSB0505HB cooling fan is a direct replacement part for specific HP laptops. It suits owners of the 4530S, 6460B, 8460P, 8470P or 4730S models who need to restore original thermal performance. The unit operates at 5V and draws 0.4A through a 4-pin connector. It arrives new and ready to install.

Check part number and connector before ordering

Verify that your current fan carries part number 641839-001 or 646285-001 and matches the 4-pin interface shown in the reference image. Confirm the model label KSB0505HB and the BK48 V000270990 marking on the existing assembly. Ensure the laptop chassis provides the correct mounting points for this specific fan housing.

Replaces worn or failed OEM cooler in listed HP

This fan replaces the factory-installed cooler when it becomes noisy, spins inconsistently or stops entirely. The upgrade is worthwhile when temperatures rise under normal load or the system throttles due to a degraded bearing. It restores the original airflow specification without modifying the thermal solution. Buyers needing a different voltage, pin count or form factor should look elsewhere.

Questions about this item

Does the package include mounting hardware or just the 4-pin KSB0505HB fan?

The package includes one CPU cooling fan (model 641839-001) only. No screws, brackets, thermal pads or cables are listed, so those must be sourced separately.

How do I confirm this 4-pin 5 V 0.4 A cooler fits my specific HP laptop?

Match the part number on your existing fan to 641839-001 or 646285-001 and verify the model sticker reads KSB0505HB. The supplier lists compatibility with HP 4530S, 6460B, 8460P, 8470P and 4730S.

What does the 0.4 A current draw mean for everyday use on a 5 V rail?

At 0.4 A the fan draws roughly 2 watts from the motherboard header, a low load that most laptop 4-pin fan connectors can supply without affecting battery life or triggering thermal throttling.
