6950 Fan adjustment with RBE possible ?

Hi,

i have 3x 6950 modded to 6970 in CF.

With this combo i have to run GFX fans faster.

Till now i used MSI Afterburner to adjust fan speed, but in some Games (iracing) i have micro stutter because of running MSI Afterburner.

Now i tried to adjust with RBE but nothing changes. The fans runs slower than adjusted with RBE, like in Original setting.

Here, see what i changed:




Did i something wrong ? Is RBE Fan Adjustment compatible with 6950 Cards ?

Thx......
