Can anyone suggest a way of fixing the > readout or help me figure out what is wrong? For 3-pin fans, there is no guarantee that speed readouts remain correct with fan speed control in action. Some chips are smarter than others to deal with the weakening speed signal. We do not have any datasheet for the ASB100 but it's pretty old so I would be surprised if it dealt with that properly. So I suspect there's nothing that can be done in your case. Also note that the lack of datasheet for the ASB100 means that the fan speed control implementation is experimental and not guaranteed to work in any way. So I am not overly surprised that you experience problems with it. -- Jean Delvare http://khali.linux-fr.org/wishlist.html
