Frequently asked questions
Which connector variant fits a Whatsminer M30S++?
The Whatsminer M30S++ chassis uses the 4-pin 5557 square header — select that variant at checkout.
Will this fit an Avalon A1246 / A1346?
The Avalon A1246 / A1346 chassis use the mini 4-pin square keying — select that variant. Confirm against the original fan plug before ordering.
Is the RZ14038H12B-6 PWM-controlled?
The fan accepts standard tach and speed-control wiring on the corresponding pin positions. Match the variant to your chassis fan header and the control board will read RPM and modulate speed normally.
Can I mix RZ fans with original Whatsminer fans on the same chassis?
Yes, but the airflow and RPM curves will not match perfectly. For best results, replace both fans in a chassis at the same time.
