OK so this morning I installed my second card which is recognised fine and all set up ready, the only trouble is that I can't control the second fan, with the new card in the second slot the original card's fan is running fine but it seems to be stuck at full, with the old card inthe second slot it's fan seems to rev up to 100% then stop, and repeats this every 5 seconds or so.

Both cards on their own work fine

I've already tried uninstalling/reinstalling drivers but this made no difference.

Basically whatever card is on the bottom seems to have no control of the fan and it either stays at full speed or revs up and stops repeatedly. What is going on and how do I stop it?
