Try checking if your thermal paste isn't dusty looking on the GPU. I've had something similar like that happen to me once before.

Be sure to check your ambient temperature and improve cable management if you haven't already.

Another thing to note is that you should buy memory heatsinks on for your Video card.

Just use Afterburner to monitor your temps and change the fan speed.

Turn them up high enough that the cards don't go above 80*C while under load.

If it's quiet to you or you don't mind the noise, then go as high fan speed as you can.

will Afterburner keep the fan speeds on all three cards when goes into crossfire?

If your chassis allows for a side panel fan, for gods sake, get one. Put fans pointing at them from the front and/or from the side.

Turn the fan speeds way up, the cards are probably stacked so close that the fan doesn't get good ventilation.
