Regarding the pinout, yes. The SP20 fan datasheet is available
hereRegarding current rating - we checked again regarding the connector UL specification. In order to meet them, the maximal current allowed is 2.5A (not 3A as I wrote earlier). Also, 24AWG wire is required to meet this current rating.
thanks for the spec PDF. I was misleaded by the safety current which is 2.12A+/-10% and printed on the label of the fan.
