What is the fan in the exhaust of Avalon 741?

Hello,

The exhaust fan (inside the black shroud) on the Avalon 741 got broken, does anyone know what are the specification of the fan?

Thanks all!

If you got the miner either directly from Canaan a few months ago or from one of their official distributors, contact them and open a a support ticket. Had a fan in a A721 die and they sent me a new fan and shroud pretty quick no charge.

No, that fan you linked will not work, it is a 3-pin fan without PWM control possibility.
And as Phil said it is only 150 cfm.

The stock fan for the AvalonMiner 741 is Cooler Master A12038-60BB-4RP-F1  12VDC 2.7A fan.

Delta fan which Phil gave a link is good one.


Also Sanyo has a good fan that I used to have installed with my AvalonMiner 6.0 (thanks to Phil and his group buy):
