+ | We use the San Ace 40 fans, taken from an old server we've got. They have a proprietary 12 pin connector. After further inspection, we found out, that they are actually 4 3-pin Fans. | ||
+ | |||
+ | Here are the pinouts: | ||
+ | |||
+ | ^ Fan 1 ^ Fan 2 ^ Fan 3 ^ Fan 4 ^ | ||
+ | | Red: +3V | Red/White: +3V | Orange: +3V | Orange/ | ||
+ | | Black: Ground | Black/ | ||
+ | | Yellow: Tachometric Signal | Yellow/ | ||
+ | |||
+ | 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. |
