Martech 7000RPM 140mm cooling fan for Antminer S21XP S21pro S21+

The Martech DF1403812B2FN 12VDC 5A 140mm x 140mm x 38mm cooling fan is used to replace the damaged case fan in Antminer L11, S21XP, S21pro, and S21+. When the fan is under heavy load for an extended period, it may lead to inadequate heat dissipation and reduced fan speed. Timely replacement of the faulty fan can help miners dissipate heat normally. The fan uses maintenance-free double ball bearings, delivers sufficient and stable airflow, and is strong and durable.
