Re: Bitmain Launches the New Antminer T9 Bitcoin Miner

what's with the difference in fan speeds?

The push fan is slower with a resistor in the feed wire. This lowers back pressure from blowing too hard into the heat sinks.

but are the same fans models right? who controls the speed? is any order you should connect the fans on the main board?
