Tesselator
macrumors 601
Yours is an 08 (3,1) machine is it not?
Works fine on 09 (4,1) and later machines, clearly for the 08 machines the fan codes are different.
No, the machine I "use" is a MacPro 1,1 recently burned to 2,1 status. And yes AFAIK we're dealing with three quite different versions of SMC. What works in one stands a good chance of not working in the other two.
