Replacement Laptop CPU Cooling Fan

The DBTLAP NS85C30 is a direct-replacement cooler for compatible laptops. It ships new and includes a single 4-pin fan unit tested before dispatch. Buyers should verify the part number against their original component before ordering.

Upgrading From A Failed Or Noisy Stock Fan

This unit replaces an original fan that has stopped spinning, runs loudly or overheats under load. The jump is worth it when the existing cooler no longer maintains safe temperatures or produces audible bearing noise. Matching the exact NS85C30 part number ensures proper fitment and connector alignment.

Sustained Operation At Rated Voltage And Current

The fan operates at 5 V and draws 0.50 A during continuous use. Stable power delivery maintains consistent airflow over long sessions without the speed drops seen in short bursts. Each unit is tested to confirm reliable performance under sustained thermal load.

Questions about this item

Will the NS85C30 4PIN fan fit my laptop's existing mounting points?

The fan uses a four-pin connector labelled DTA51661PER; compare the screw-hole layout and connector orientation in the product photos with your original fan before ordering.

What is the common mistake when installing this DC05V 0.50A replacement fan?

Many installers forget to peel the protective film off the thermal pad or reuse the old pad, which blocks heat transfer and can raise temperatures by 19C18.

How often should I clean or replace the NS85C30 cooling fan?

Blow dust from the blades every six months; plan to replace the fan after roughly five years of continuous use or if bearing noise appears.
