Replacement Fan for HP ProBook 450G1 455G1

This replacement CPU cooler is built for HP ProBook 450G1 and 455G1 laptops. It matches part numbers 721938-001, KSB06105HB-CM16 and 23.10754.001. Each unit is tested before dispatch to confirm it spins correctly. Buyers who need a fan for a different laptop series cannot use this part.

Thermal Performance and Power Draw

The fan runs on DC 5 V and draws 0.40 A during operation. It is designed to maintain the original thermal profile of the supported ProBook models. No alternative voltage or current ratings are provided. Users who require a higher airflow specification or a different voltage standard will not be served by this component.

Installation Fit and System Impact

The package includes one fan ready for direct swap into the compatible chassis. No additional mounting hardware or cables are supplied. It frees the system from overheating caused by a failed original cooler. Builders working on other HP models or custom chassis must source a different cooler.

Questions about this item

How do I install the DC 5 V 0.40 A CPU fan in my HP ProBook 450G1 or 455G1, and which step do people often miss?

Remove the bottom cover, disconnect the old fan cable from the motherboard header, swap the fan, then reconnect the cable firmly — the step most people miss is reseating the connector so the 0.40 A signal registers.

What maintenance or replacement will this Forcecon, ADDA, Sunon or Kipo fan need later?

Clean dust from the heatsink fins and intake vents every few months; if bearing noise or speed drop appears, replace the whole fan unit — no separate parts are serviceable.

What limit appears first when this 5 V 0.40 A cooler runs under sustained load?

The 0.40 A current ceiling caps maximum RPM, so thermal headroom hits its limit before the 5 V supply does.
