iCyclone lets the user set the minimum speed of the built-in fans. So you can increase your minimum fan speed to make your Mac run cooler with manual mode or let the program set the minimum fan speed for an apporpriete Idle temp with Automatic mode. In order not to damage your machine iCyclone does not allow you to set minimum speed to a rate under Apple's defaults.
