I recently bought a single CPU 4,1 which i'm working on and testing.
Comparing the DUAL 4,1 and the single 4,1 ,I've noticed a significant difference in Temps of e.g. NorthBridge and respons to the FAN settings.

Based on the recommendation of different people including @h9826790 , i tested the influence of Exhaust Fan in my DUAL MP, and didnt see a significant effect on the CPU A Temps.
What seems to be more effective is to increase the Intake and/or Boost A fans.
So by lowering the min rpm and max rpm in the previous setting for Intake and Boost A, you may be able to lower CPU A without the noise of the Exhaust Fan running at 2000rpm.
In other words: with Intake and Boost A running a bit faster, you may get the desired effect.

After all fan settings depend on lots of factors and personal preferences play a role too...
Personally i like to see very low Temps...

Yes - that's what i'm finding ... Exhaust doesn't seem to do much apart from make a lot of noise !

I'm playing with fan settings but happy with the ones suggested ...
