SpeedFan allows for the monitoring of temperatures from various sources within your system. By adjusting the settings in SpeedFan, you can enable it to alter fan speeds according to the temperature readings. When determining the minimum and maximum fan speeds, it's advisable to manually adjust these settings while listening for noise levels from the fan; when the fan is silent, that speed can be noted as the minimum. It is generally recommended to set the maximum fan speed at 100, but if the fan is excessively noisy, you may consider lowering that limit to 95 or even 90. In some instances, I have opted to set it at 60 as the maximum value. It's important to note that once the warning temperature is reached, the software will automatically ramp up the fan speed to 100, regardless of the maximum speed you’ve defined. Additionally, it’s worth mentioning the fan x listbox feature; on my computer, multiple temperatures can shift when a single fan operates at a higher speed, so it's crucial to configure which temperature corresponds to each fan for optimal performance. This personalized setup allows for better cooling management and noise reduction, enhancing the overall efficiency of your system.
