ok, just got a 2nd ATI 3870 for my Mac Pro 2008. THe fan is just as loud or slightly louder than the 1st one. *ugh*. So I downloaded smcFanControl 2.2.2 to see if I can up the fan settings to cool the machine down to hopefully slow lower the fans on the 3870's.

I cranked them up about 30%. What does IO, Exhaust and PS relate to. I assume the fans to these components

What settings are you using and how did you ascertain the percentage increase (or decrease)?
 
ok, just downloaded iStat Pro and iStat Menus. I figure IO = HD/Expansion, Exhaust = Back fans, PS = Power supply
