SGMiner - Auto-fan not doing its job, and can't set static fan speed

[VMey]

Hi all,

I'm running SGminer on BAMT and I've been working on optimzation all night.  But right now I'm struggling on temps.

I have three R9 290s and one HD 7850, and I'm averaging around 2700-3100 khs between the three.

But my temps on the 290s are out of hand.  I have had auto-fan in my conf file, and then I tried to make a static fan speed, but I can't get above about 50% fan speed no matter the settings I put in.

I've got a box fan pounding away too, but still seeing temps around 93-94 on the 290s, and fan speed at 48-53%

Thanks for any
