Hi, my Rig : MOBO ASUS Rampage Extreme CPU INTEL C2Q Q9650@4,2GHz GPU ASUS GTX280@648/1458/1242 RAM OCZ Platinum Edition DDR3-1600@1557MHz 7-7-7-24 1N Drivers GeForce 182.06 WHQL OS Windows XP Pro SP2 I have installed Rivatuner 2.23, and the automatic control fan through "scheduler" doesn't work. The fan duty cycle still stays at 40% whatever the core temperature. In "scheduler", as I always did with former versions of Rivatuner, I have set steps with "hardware monitoring threshold event" to have speed fan at 40%, 60%, 80% or 100% depending on the core temperature (I use upward and downward). For all former versions it worked perfectly and not for 2.23. I came back to 2.22 version. Anyone has this issue with the same rig as me ? I think there is a bug....Hope it wil be solved with 2.24 version Bye.
