120 mm fans
The 12038 and 12025 frames — the standard on every Antminer generation plus Avalon, IceRiver and the Scrypt machines. Speed is what matters, not size: 6000 RPM for the S19 family, 7000 for S19 XP and S19k Pro, 8000 for S21. Fitting a slower fan makes the machine throttle on temperature and log a fan error.
