Lenovo Xiaoxin Pro 16 2021 GPU Cooling Fan

This replacement GPU cooling fan is built for the Lenovo Xiaoxin Pro 16 2021 laptop. It suits owners who need to restore factory cooling performance after the original fan fails or becomes noisy. The part targets repair technicians and experienced users comfortable with internal laptop disassembly.

5V 0.5A thermal performance

The fan runs on a 5V 0.5A power draw, matching the original electrical specification. Each unit is tested before shipping to verify airflow and bearing operation. Proper installation returns the GPU thermal curve to its design intent, reducing throttle risk under sustained load.

Exact part-number compatibility

Compatibility is locked to part numbers DFS5K221155720, FNG2 and HQ23300128000; buyers must verify these against the old fan before ordering. The package includes only the fan itself, so existing screws, cables and thermal pads must be reused. This single-fan design does not address CPU cooling or multi-fan configurations.

Questions about this item

How do I install the GPU cooling fan in my Lenovo Xiaoxin Pro 16 2021 and what step do people often get wrong?

Match the part number DFS5K221155720 FNG2 exactly to your laptop before opening the case; the most common mistake is ordering a similar-looking fan with a different connector or mounting layout.

What maintenance or replacement will this fan need later?

The fan is a mechanical component rated at 5V 0.5A; expect to replace it when bearing noise increases or airflow drops, typically after several years of continuous use.

What limit shows up first under sustained use?

The 5V 0.5A power envelope caps maximum speed, so prolonged heavy loads hit the current limit before thermal headroom runs out.
