Official Martech fans, the same ones Bitmain fits in the machines. Pick your reference above:
DF1203812B2FN — 120 × 120 × 38 mm, 12 V 4.5 A. For the Antminer S21, T21, S19j XP, S19k Pro, KS5, KS5 Pro and L9.
DF1403812B2FN — 140 × 140 × 38 mm, 12 V 5 A. For the Antminer S21 Pro, S21+, S21 XP and L11.
The two sizes are not interchangeable: a 120 mm fan does not fit an S21 Pro or an S21 XP, and a 140 mm one does not fit an S21 or a T21. If you are not sure, measure the frame of the fan you are replacing.
Both at 7000 RPM, with double ball bearings and a square 4-pin PWM connector. Sold per unit.
