Snowfan YY12025M12B – 120 × 120 × 25 mm Cooling Fan for Canaan Avalon Q 90 TH Miner
The Snowfan YY12025M12B is the 120 × 120 × 25 mm cooling fan fitted inside the Canaan Avalon Q 90 TH home miner. Running at 12 V DC, 0.54 A and 4000 RPM with a low 35 dB acoustic signature, it keeps the Avalon Q's hashboard and PSU within spec while preserving the "quiet home miner" profile Canaan designed the Q around. A damaged or worn bearing on this fan is one of the most common reasons an Avalon Q throttles down or starts chirping — a fresh Snowfan restores full airflow and brings noise back to factory levels.

When to Replace the Avalon Q Fan
Common failure signs: miner throttling under normal ambient temperature, a new buzz / tick / chirp from the chassis, "fan fault" in the Canaan control panel, or a rotor that spins freely but never hits rated RPM. Because the Avalon Q is designed around a 25 mm-thick fan, always replace with the same thickness — a 38 mm fan will not fit the slim housing and a different connector pinout will trip the controller.
Installation Notes
Power the Avalon Q fully off and disconnect the PSU. Remove the fan grille, unseat the 4-pin KF2510 connector, and match the replacement's airflow arrow to the original. Seat the new connector with the latch engaged so the controller can read RPM. No firmware change is needed.
