CH6 issue with fans getting stuck on max/high RPM bios 1401 & 1403.

Hello,

I did also PM this directly to @elmor on Overclock.net.

I seem to have some sort of bug with bios 1401, which is also present in bios 1403.

When I benchmark my system hard, or play an intensive game my fans (both CPU fans and case fans) get stuck at whatever peak RPM they reached/max RPM.

It also appears that it can happen at random, as I came home from work today to find my fans running at a higher than usual RPM, yet my system fully functional and working as normal. To clear the problem I have to reboot, but the issue will come back next time I do something intensive.

Prior to 1401/1403 I never had an issue.

I've noticed a few others have also reported this on the Overclock.net thread with the previous bios (1401).

I reset the bios to optimized defaults both times and have also tried clearing the CMOS - this hasn't made any difference and the issue persists.

Fan setup is as follows:

  • CPU_FAN - Y-splitter connected to 2x 140mm Noctua radiator fans.
  • CPU_OPT - Y-splitter connected to a further 2x 140mm Noctua radiator fans.
  • AIO_PUMP - My H115i header is connected to this for pump RPM readout.
  • CHA_FAN1 - Not connected.
  • CHA_FAN2 - 120mm Corsair HD120 case fan (top).
  • CHA_FAN3 - 120mm Corsair HD120 case fan (rear).

My CPU fans (2*sp120 on PWM Y splitter) would stay @100%. I had to change from PWM to DC as that’s the only thing that would stop it. I have not tried the new beta BIOS’s though, I’m on 1201.

Corsair Vengeance® LPX 16GB (2x8GB) DDR4 DRAM 3200MHz C16 Memory Kit - Black (CMK16GX4M2B3200C16)

1403 bios
Ram did not work properly
Value did not work when I entered
2666 default vs 3066 mhz working
3200 mhz not working


1401 bios
2666 default working
Works properly when you enter values
16.16.16.16.39 voltage auto 3200 mhz Stable working
