I'm running 2 x1900xtx cards in crossfire. The fans never speed up when they get hot. So I installed atitools .25 . The master card spins up as is heats up, but the slave card doesn't. Any ideas how to get them both to spin at at the same time, or with temp increases? They get hot when I ramp up the Clock and memory speed in ati's catalyst control. Any Ideas?
