Detect dual GPU cards via the indirect information of - 1st card has a fan controller. 2nd card does not have a fan controller, cards share the same device name, and are one bus ID apart. Use this information to create paired devices, displaying the fan speed on both devices and using the hottest temperature from either GPU to control the overall fanspeed.
