Hi guys,
I once solved the problem with a resistor between sensor and ground. It does not seem to work this time.
Exactly.Are you trying to get the computer to not give you the "CPU fan fail" warning at boot?
That´s not an option in this custom-made BIOS/MoBo.Look in the bios settings for a setting about CPU fan check and disable if possible

If you have an extra fan and your motherboard can use speedfan, just connect the extra fan and set speedfan to auto disable to fan after booting into Windows.
That's what I do anyway. My mainboard is also OEM with no option to disable CPU fan warning. And I have a Scythe Ninja to run fanless an undervolted A64 with.

Hi,
no success yet, fan speed control is very problematic these days...

Hi
What have you tried so far without success?

stinius,
I have a 4-wire processor fan working nicely and a 3-pin system fan connector, however, I rather need a small 2 terminal fan for the video card. Interconnecting the speed sensor outputs did not help. A hardware solution would be preferable.
Hi
As I told you here you will need to make a circuit that “simulates” a fan, on the control pin.
It’s as simple as a 555 with some extra components. I can email you the circuit if you drop me an email.
You can also try it by putting a square (digital) signal on the control pin, in the 35Hz to 150Hz range.
Cheers
Stinius
stinius,
would you please send me the circuit scheme, if I emailed you?
Yes.
