After further inspection, we found out, that they are actually 4-3 pin Fans. | + | We use the San Ace 40 fans, taken from an old server we've got. They have a proprietary 12 pin connector.

Sadly, these fans are not reversible, but there is a pin not connected on the PCB, maybe by soldering the +V wire to that pin, we can reverse the fan. | Sadly, these fans are not reversible, but there is a pin not connected on the PCB, maybe by soldering the +V wire to that pin, we can reverse the fan. | ||
The voltage mentioned in the table, is the minimum voltage needed to start the fan. The maximum voltage is +23V after that, the fan start to lower their speed. | The voltage mentioned in the table, is the minimum voltage needed to start the fan.
