Looks like the fan speeds now do change and the maximum CPU temperature I was able to get (and only briefly) was 72C. If you have a multi-speed fan with a single 24 volt wire, the speed of your fan is not controlled by your thermostat. Varying the voltage ±10 % will also cause the speed to vary by 10 %. Just seems like crazy high temps with a water cooler, i mean at stock he should not be seeing those temps unless he was using the stock heatsink which was crap. Ceiling fan speed control switches are usually wired such that the switching sequence runs Off - High - medium - Low - Off, so that the fan starts up with the full-speed capacitance to get it going. Fan Control is a fan speed manager for any macOS device. OptiMOS™ driver PX3517 and PX3519. Smart features include over-speed and impact detection along with temperature, voltage and current monitoring. The average voltage will be supplied to the DC motor. About Lenovo + About Lenovo. PWM INPUT CURRENT (IPWM) RANGE: 40uA to 20mA You'll probably need to do a bit of experimenting with capacitor values, but a rough guess would be to choose a full-speed total capacitance of about 10x the value which just barely allows it to start. If the fan has no speed control input (this is the case for all 2-wire fans and most 3-wire fans), there are two options for controlling the fan’s speed. Sprint 450mm 220-240 Volts High Speed Pedestal Fan by Havells The fresh, cool breeze will fill your room! How can we apply PWM to the fans inside our computer?
