IP35 PRO fans problem.

[Robat]

Hello,

I'm building my first system and got problem with fans.
CPU fan and all case fans which is connected to motherboard AUX connectors don't spin, only system fan
is working.
The motherboard IP35 pro, case Lian Li A70b, Enermax 720 Watt Infinity PSU, 12mm fans in case and
12mm Noctua on CPU heatsink
The fans is working if I plug them straight to PSU, and PSU fan reads in BIOS on any fan connectors,
but not case fans and CPU fan.

Hope this make sense, sry for my English.

Hi,
CPU fan connected to CPUFAN1 connector,
first exhaust fan connected to SYSFAN1 connector, second exhaust fan to AUXFAN1.
Two intake fans connected to AUXFAN2 and AUXFAN3.
PSU fan regulator connected to AUXFAN4 connector.
from the whole lot only SYSFAN1 working and PSU fan regulator can be read from any connector in BIOS fan control thingy.
I tried to clear CMOS, but still no luck.
Should I return this board to retailer (or RMA?) as i'm very eager to get my system runing by weekend.
thanks for help.

If there is no power to the FAN headers I would recommend returning the motherboard to the place of purchase.

Are you sure it isn't because they are temperature controlled and temps are so low the fans are not spinning up? Unlikely but you never know....

Also some fans will only accept molex power and only have monitoring for board headers.

If that was the case the fans would still spin in the first few seconds from power on.
