Run "lspci -tv" to see what cards are installed and recognized by your system. Typically your GPUs are recognized in order of how they are physically installed: your first (usually top) GPU will be #0, your middle one will be #1, and your last (usually bottom) one will be #2.

What do you mean you don't agree with it? You mean you don't believe me? Or you tested it and proved it not to be true?

Mine on one card at a time, disabling the others from the menu while it's running. See which one the fan speeds up on.

There is absolutely no way to tell from the operating system since it's up to the bios to enumerate them and there is no standard by which all manufacturers adhere to.
