Rivatuner will work for the 3870x2, and I know because I'm using Rivatuner with mine. You do have to modify the config file a little bit. It's real easy to do.
I just installed Rivatuner 2.07 last night, my hope being it will allow me to control the fan on my Diamond 3870. Well, so far I can't use it to control the fan on my Asus EAH3850; I can define launch items and do it manually, but the [+] to add threshholds to the monitor (e.g. for Core Temp) is missing. The fan runs at 100% all the time. It's a VERY quiet fan, so I don't plan to go back to Rivatuner 2.06 which worked, but this option would not work for the 3870, which has a very loud fan.
Can a Zalman vf-700 be used on a 3870?

There is ALWAYS a drone. Exactly where, or how many drones you will encounter may vary, but that there will be at least one will not.
I really wish ATI would include this sort of control in the CCC. I too would like to up my fan speed. If Riva and ATI tools can do it, I think ATI should be able to figure out a way.
