Title: Z68MA-D2H-B3 r1.0: SYS_FAN header not working.
Post by: MarkJohnson on January 11, 2012, 11:55:59 pm

I turned my Z68 board into a FreeNAS server and my system fan header isn't working.  I use an 80mm fan to cool my hard drives (2 x 2TB).  One is a WD Black drive and runs very hot.  over 50C idle.  So I put the fan on the MB SYS_FAN header and it doesn't turn on.  I go into BIOS and find no settings for the SYS fan except a warning.  I enable the warning in hopes of more menu options, but no luck.  I reboot and it beeps like mad, so I go back into BIOS and disable the warning.

I found a 3-pin fan header to a molex connector adapter and the fan works fine.  I'd like to get rid of the adapter if anyone know how to get the SYS_FAN header to work.

I have BIOS F9 installed

Thanks in advance

Hi

If you have it enabled in the BIOS by disabling Smart Fan Control it should be working at it's full speed. I can tell you however that the SYSFAN_2 header only works at half the power/speed of the other headers so whether that has any effect onyour fans functioning I don't know.
