Summary0002352: Feature request - fan deadzones
DescriptionI'd like (if possible) for fan percentage deadzones to be implemented if possible! I understand that you are probably very busy, but if you had time a deadzone feature would be great. At about 10-43% my fans don't run properly, but only sort of move a little bit and then stop, then when the next signal is given move another slight bit and then stop again, and do not run continuously given more percentage/power. If possible, could a deadzone system be implemented so I could stop the fans running at 10-43% so I could turn them off when the system is cool, then turn the fans on at 45% and then upwards so the air is delivered? The advanced fan control doesn't seem to help much with this, as it still gives figures of about 30% which just turns the fan slightly and then it stops.

Thanks in advance, I hope you'll consider this!

I am working on this.
Are you sure that you cannot properly configure the advanced fan control strategy to overcome this issue on your system?

That's impossible because you forbid any high fan speed values before low speed values on a curve. Therefore, one can't make the fan start at high speed and then go slow.

PS But there's no problem to stop the fan when not needed and then start it with high enough speed. I'm using this kind of curve with my CPU cooler. That's why SpeedFan is great software ;)

Thanks for the replies.

I have tried multiple options with the advanced curve and there's always a 1-2c area where the fans do the behaviour I described. It may well be my motherboards fault but I simply can't stop it from doing it no matter what I try on the advanced fan curve.

Sorry, I misunderstood what you defined a deadzone. I thought you wanted to skip those PWM values.

Yes sorry that is still what I mean. The fans when they reach around 5%-45% pwm power on the advanced fan curve do the behwviour I described, hence I want to miss out the pwm values from about 5% to 45%

Since I will soon be working on this topic, I will keep in mind your request too.

That's right. Deadzones can be a good thing. It's just doesn't bother me when the fan tries to start at low speed sometimes. The fact that the fan starts spinning is enough for me. But I'd prefer to have deadzones set up, too.
