Replacement Heatsink Fan for HP Pro 450 G1 455 G1

This new DBTLAP cooling heatsink with fan is a direct replacement part for HP Pro 450 G1, 455 G1 and 470 G1 laptops. It matches part numbers 721938-001 and KS06105HB-CM16. The package includes one fan unit that has been tested before shipping. Buyers should verify the photos against their original cooler to confirm fit.

Thermals Noise and Power Draw in Normal Use

The fan draws power from the laptop's internal header and spins to move air across the heatsink fins. No separate power adapter or software control is required. Acoustic output and power consumption are determined by the host system's fan curve. Each unit is tested before shipping to ensure it operates correctly.

What This Replaces and When the Jump Is Worth It

This cooler replaces a worn, noisy or failed original heatsink fan in the supported HP Pro models. The upgrade is worthwhile when the existing fan no longer spins freely, produces rattling sounds or allows the processor to throttle under load. It is not suitable for laptops outside the listed part numbers or for builders seeking additional external cooling capacity.

Questions about this item

How do I install the heatsink and fan assembly on my HP Pro 450 G1, and which step is most often missed?

Remove the bottom case, disconnect the old fan cable, unscrew the heatsink, clean old thermal compound from the CPU and GPU dies, apply fresh paste, fit the new heatsink and fan, reconnect the cable, and screw it down. The step most people skip is cleaning both dies and applying new thermal paste.

What maintenance will this cooling heatsink and fan need later?

Blow dust from the fan blades and heatsink fins with compressed air every few months. If the bearing becomes noisy or airflow drops, replace the whole unit — the package includes 1 x fan tested before shipping.

What is the first limit that appears under sustained heavy load?

The single fan can only move a finite amount of air, so thermal throttling of the CPU or GPU will occur once heat output exceeds the heatsink's dissipation capacity.
