Summary0000093: Fan speed changes only in 0-10% range. In that range 1% change is too big.
DescriptionEg. one of my fan has max speed of 4200 rpm. In 20% setting the speed is 3800 rpm, what is minimal change compared to the change in the speed setting. In 10% setting the speed is 3400 rpm again, minimal change compared to the 20% setting. The speed change is only significant in 0-10% setting, but in that range the step is too big (1400 rpm @ 2%, 1900 rpm @ 3%).
Would be good to have a radio button to select linear or logaritmic scale to control the speed.

I'm considering a workaraound, but this is, IMHO, due to poor circuitry design and not following the datasheets. Anyway... I hope to be able to find a workaround.

I'm working on a workaround to this issue. Would you like to try a beta?

Thank you for working on this issue.
As I reported nearly two years ago, on my MS-6701/W83697HF I get:
1722 rpm at 0% (no noise)
3013 rpm at 1% (pretty noisy already)
3516 rpm at 2%
3792 rpm at 5%
3979 rpm at 10%
4018 rpm at 100%
I would love to try a beta.

Could you, please, drop me an email?
I will answer to that email with a 1MB ZIP file containing an EXE.
I don't think I'll be able to send it to you tonight, but I should be able to send it to you during the weekend :-)

I have 2 AOpen Ak79* nForce2 motherboards that do the same thing. Will this workaround be generic, or motherboard specific?

Ten days ago I sent you the email you asked for but didn't receive the beta.
Still eager to try one if you wish.

Same here. I have not received the beta what I requested in e-mail.

Alfredo, I have got the same problem and would like to try the beta version as well. Could you please send it to me when available at e-mail address 'valentin.pankov@mail.ru'. Thank you.

This is not a SpeedFan issue. It depends on the circuitry on the motherboard, on the fan model and on the PWM CLOCK used to control the fan.
