What results did you get?
So far it is running around 86% fan speed (it was 100% before) with chip temp at 67 C. The hash rate is staying between 10.5 -10.8TH - with the offset of 0, it was 11.2-11.5TH.
Overall it is much quieter but I will probably keep working with it tomorrow to see that new fan ramping point can be adjusted and may the shutdown temp set to the standard 99.
Screenshot after one hour with offset of -2 (sorry I don't have a before screenshot - if I have time I'll try to set it back tomorrow and let it run for an hour to directly compare):

The shutdown temp on both that 741 and 821 is 105 in their respective versions of cgminer (you can see the 7's version by selecting the avalon7 branch in git)
I found that the min fan value was picked up from the configuration screen, by default it was 100%, but if you changed that to 50%, you would get the 50-100 range in to the process listing of startup options. I had tried the -x values, but didn't even think to look at those being overriden.
