I see a number of threads regarding fan control. Martin has already determined that my HP laptop is not supported. The desktop I'm on doesn't show any options for fan control. The sensor is a Winbond/Nuvoton W83627THF. The BIOS has no hardware control at all. Computer is Medion, but motherboard is MS-7046, modified for Medion so many BIOS options are not available. CPU Fan is shown on Sensor Display. It's an aftermarket PWM fan & the sensor does show the rpm's varying (can hear it, too). Something is controlling it, don't know what.
