Replacement Fan for DELTA Laptop Coolers

This 5 V 0.5 A four-pin cooling fan is built to match the DELTA KDB0705HCA02D7Z part number used in compatible laptop cooling pads. It arrives new and individually tested before shipping. The package contains one fan unit only, with no extra brackets or cables included.

Fits into a cooler that expects this exact part

The fan connects through its four-pin header and draws 0.5 A at 5 V, so the host cooler must provide that connector and voltage. No additional power adapters or mounting hardware are supplied, meaning the surrounding pad must already have the correct screw holes and airflow path. Installing it restores the original cooling performance without modifying the pad.

Suits owners who have verified the part number

Buyers who have compared photos and confirmed the KDB0705HCA02D7Z marking will get a direct drop-in replacement. Anyone uncertain about their cooler's exact model should check the supplier's compatibility offer before ordering. This unit does not fit pads that use a different connector, voltage, or physical layout.

Questions about this item

How long will the 5 V 0.5 A fan run before thermal throttling becomes the limiting factor?

The 5 V 0.5 A rating defines the steady-state electrical limit; sustained operation stays within that envelope as long as the laptop chassis provides adequate airflow.

What noise and heat levels should I expect when this 4-pin Delta fan runs continuously inside the laptop?

The fan draws 0.5 A at 5 V, so waste heat is minimal; acoustic output matches the original Delta specification for this part number.

Which laptop models or motherboard headers are confirmed compatible with the KDB0705HCA02D7Z 4-pin connector?

Compatibility is tied to the exact Delta part number KDB0705HCA02D7Z; verify your service manual or original fan label matches this number before fitting.
