    What is the marking of the motherboard platform?

        How many V you got on yellow wire?
        Just cook it! It's already broken.

                Take the fan out and check without all voltage

                  i found switching mosfet for fan and one leg have 5V, second have 4,1V and third leg have 2.98V. to fan is going 2.98V. maybe that mosfet is bad because the voltage to fan slowly rising.

                  without fan red - 5V and orange 3,3v

                      now i realy start to think that mosfet is bad. when fan stops, i have 5V on drain, 5V on the base but 0V on source to fan

                      or maybe its P-channel

                      when i jump drain to source the fan goes on full speed

                      marking on the mosfet is A5w98, maybe somebody know what mosfet it is

                          So without fan you got correct voltage.

                          Putt another fan for test and see voltage again

                            i put one from HP but it not spin, it gives some sound like low voltage for spin

                              i replace the mosfet with some N-channel mosfet and now have 5V on drain, 5V on base and 4,25V on source to fan. its little soundy to me but i asemble it to instal system and check temperatures.

                              still waiting for help with schematic to be 100% sure its good work.
