DBTLAP Laptop GPU Cooling Fan FN51 12V 0.8A

DBTLAP FN51 GPU Cooling Fan

This replacement fan is built for Lenovo Legion 5, 5i, Y7000, Y7000P, R7000, R7000P and Y550-15E laptops. It operates at 12V with a 0.8A current draw to match the original GPU cooler specifications. Each unit is tested before shipping to confirm correct operation. Buyers should verify the part number DFSCK22115181Q against the existing fan before ordering.

Replaces Worn Original GPU Cooler

The FN51 serves as a direct swap for a failed or noisy factory GPU fan in the listed Legion and Y-series models. Installation is justified when the original cooler develops bearing noise, reduced airflow or complete failure. The jump is worth it when thermal throttling appears during sustained workloads and the existing fan no longer spins at rated speed. Compatibility depends on an exact visual match with the product photos provided.

Sustained Load Thermal Behaviour

Under continuous GPU load the fan maintains a steady 12V 0.8A draw to keep the graphics module within its thermal envelope. The design targets consistent airflow rather than short burst spikes, helping prevent clock throttling during extended gaming or rendering sessions. Each fan is bench tested to verify it sustains the rated current without deviation. Buyers needing a second fan for a dual-fan chassis or a different voltage variant cannot use this part.
