Hi everyone. I just bought myself an XFX 9800GT. I installed Riva Tuner to increase my card's fan speed to make it run cooler during games. My fan speed has been set to 70% on startup. Before I start playing I set my fan speed to 100%. However, while playing NFS Most Wanted I find that after sometime the fan speed drops to its default value of 40%. I can't understand why this happens. When I'm not playing the card maintains whatever speed I set it to. Please help.
