Thread: Reliable CPU fan speed controller?

Started 1 month, 3 weeks ago by jd
I have a CPU fan that runs all the time at around 4,100 rpm. This is completely unnecessary when the weather is cool. I believe a speed of about 3,000 should be ok at present. Is there any such program around? I know about SpeedFan but I think it's a primitive piece of work. The CPU needs a delicate touch. I did a search and found http://wareseeker.com/free-cpu-fan-s...trol-softwa re/...

There all the voltages can be allowed to vary a little e.g. 12V is set to vary from 13.2 to 10.8. Same for CPU core (+1.52V), set to go from 2.325 to 0.725. There is no variation for the processor fan. Back tomorrow :-)...

Speed changes can be attempted on SpeedFan but they do nothing and my CPU fan is still running at about 4,300 rpm. The BIOS has a variable setting for the fan or fans but it seems to be dead too. Personally, I'd just solder a 2W, 68 Ohm resistor in series with the power lead......
