Hmm.. I've replaced the fan in the back of my enermax (350w) with one of the 80mm UV blade fans from ebuyer..

thing is after taking it apart I noticed the 3pin connectors were different sizes, so I switched the one on the new fan for the one on the old.. kept the wiring the same order.. but it didn't spin up (only lit). So I kept switching wires/testing .. until it lit & spun (such a technical way to do it).

Although now; it seems I can't retrieve fan speed from it.. (comes up as 0rpm) ? :| ..
The wires on this new fan are green, orange and red (which I've not seen before).

Its spinning, lit, blowing air out and adjusting the PSU fan control does slow it down.. so I figure its ok..?
