I will overclock my Z9 mini today. Do you turn on the second fan ? Or let je de first fan more rpm ?

No need for a 2nd fan, just reverse your current fan so that it pulls air instead of pushing it through the unit and the miner will run about 10c cooler.
Because we don't have a second fan...

How reverse the current fan inside?

Just did, Let's see how that works. Is possible enable the second fan too? Because we don't have a second fan...
