Overview

This is a replacement CPU cooling fan for a wide family of Huawei MateBook and Honor MagicBook laptops. It covers the MateBook D14, MateBook 14 2019 Ryzen edition, MateBook D15 and D15 2020, and the MagicBook 14, 15 and 15 2020, across a long list of chassis codes including the Nbl-WAQ9 series (WAQ9HNR, WAQ9L, WAQ9R, WAQ9RP, WAQ9HNRP, WAQ9HNL), the WAH9 and WAE9 variants, plus the NbB, NbD, NbDE, NblL, NbM, NbR, NMH and Boh families listed by the manufacturer. It is offered in two versions: an original (ORG) fan and an OEM equivalent, and it is CE certified.

A worn fan is one of the most common laptop failures: bearings age, the fan rattles or grinds, or it stops spinning, and the laptop then overheats, throttles its speed or shuts down under load. Replacing the fan restores the cooling system for a fraction of the cost of a repair-shop visit, which is why this part exists for these very popular MateBook and MagicBook models.

Compatibility: Match the Chassis Code

The essential step is matching the part to the laptop's chassis code, not just its marketing name, since Huawei uses many internal codes across these models. The code (such as Nbl-WAQ9HNR or NbD-WFH9) is printed on the label on the laptop base. If the code on your label appears in the compatibility list, the fan fits; if it is not listed, it should not be assumed. Between the two versions, the original fan matches the factory part exactly, while the OEM version is the budget-friendly equivalent.

Replacement, Step by Step

Fitting a laptop fan is a manageable job with care. Power down, unplug and disconnect the battery once the base panel is off. Remove the base screws and lift the panel, unplug the old fan's connector from the motherboard gently, remove its screws and lift it out. Seat the new fan, secure it, reconnect the connector, and close up. While the laptop is open, it is worth blowing dust from the heatsink fins, since dust is often half the overheating problem. On boot, the fan should spin quietly and temperatures should return to normal under load.

Summary

This replacement fan is the practical fix for an overheating or noisy MateBook D14/D15 or MagicBook 14/15: broad coverage across the Nbl-WAQ9 and related chassis families, a choice of original or OEM versions, and a repair most owners can do themselves with a screwdriver and patience. The one essential is matching the chassis code on the laptop base label to the compatibility list. Done right, it restores quiet, healthy cooling to a well-loved laptop.
