No, I haven't .
I think that, since both Evga Precision and Msi Afterburner are based on RivaTuner, they are almost the same.
Is there any other way to force the fan run at full speed when I need that?
I experience low fps in games because of overheating.
Yeah, I didn't think about the RivaTuner connection, but you're right.
I really don't know of any other way besides editing the VBIOS to make it stay at 100% (or however high you want it), but that's not really what you're looking for. There may be settings in the VBIOS for the auto speeds too, but I'm not sure. That's an extreme thing to do though, that may, of course, brick the card if you get it wrong.
