My PWM chassis fan is acting weird. I think this issue excisted since the beginning but i just noticed it when installing new case fans. When in Argus Monitor setting the curve, or any other program. The fan doesnt spin below 45%, and between 45% and 99% it gradually ramps up to 1500ish rpm and at 100% goes full mad up to 2200 rpm. I would really like to control the last 700rpm as well. Any help is appreciated , thanks! kind regards.
