|Summary||0001103: Fan seems to ignore Speedfan settings|
|Description||While running speedfan on my computer (either in Vista or XP) the program is not responding after I see lines like "SMBUS msg: SMBUS $18 busy waiting IDLE (STS=$00)"|
So I decided to start it with the "/NOSMBSCAN" parameter. That worked.
I now have speedfan running.
However I can set the min and max values of my fan 2 (which is CPU) and even set it up so it is depending on tempurature. In the Readings screen I see the correct (the one I want) % on Speedfan 2 however. However the fanspeed (on screen) is always around 4000 rpm) and I can confirm this, because of the noise the fan makes.
In short, i can set things up, correct % values are calculated and displayed, however the fan chooses to ignore this and keeps running at a constant pace.
I've added some screenshots so you can see my settings.

Ok, played around with the setting a bit more.
Seems i can control fanspeed of fan 2. Just need to use the "Reverse PWMxx logic" on PWM01 and PWM02.
Other strange thing now is, that i can use PWM01 OR PWM02 to control the main fan (CPU i think), if i set either (PWM01 OR PWM02) to 100% FAN2 runs max speed. It seems I cannot control FAN1 with this program (it is probably unsupported?).
Is this normal? That you control FAN2 with PWM01 OR PWM02?? What should my settings then be for FAN1? Since it doesn't seem to be connected to a fan speed I can control.
After some additional testing it seems if i set PWM01 OR PWM02 to 50% or lower FAN2 doesn't spin. If i raise it to 55% the fans starts spinning immdiately at 2900 RPM. Each 5% raise gives me a 300 RPM higher spin approx. Is it normal that i can't set the fanspeed lower then 2900 RPM?
Although these troubles, fanspeed is working for me, fans used to run constantly at annoying speed, now i can just leave it at 2900 RPM most of the time.
However if possible I would like to set my fan speed to a bit lower level e.g. 2500 RPM if possible, so that it constant cools without the noise.
Does anyone know which motherboard model my laptop has (see specs)? And is this motherboard supported by Speedfan?
