how do i know crossfire is working?

[zooankski]

I have just installed a second 5850 on my ex-58a-ud5 (both in the x16 slots), connected the bridge, and enabled xfire in CCC.
Is there a way to tell it is definately working?
Also, in CCC overdrive? the second card shows 0% load and manual fan does not work? tried a reinstall of drivers to the latest 10.9 but no go.
I intend to do a full format and re install windows 7 64 next week so some answers on what is happening before i do would be appreciated.

any ideas if i should be able to manually control the second cards fan speed?
