It doesn't work on all machines. The author has a system to feed this back to them so my suggestion is to do that.
I'm having trouble increasing the fan speed for a stock AMD II X2 heatsink and fan. It has four pins, so I thought I was set up to change it.
I opened up SpeedFan and went into Configure>Advanced. I choose "Winbond W83627DHG at $290 on ISA" and went down to PWM 1 Mode. I was told to choose "software controlled" from the 'set to' drop-down box, though it isn't appearing. The only options I'm seeing are Manual PWM Control, Thermal Cruise, Fan Speed Cruise, and SmartFan III.
Is there something I'm missing or simply glossing over on this issue? Manual PWM Control doesn't do a thing and I'm sure the others wont either. I'm using the latest version 4.40 if that helps. Any suggestions?
