Here some informations from the programmer of SpeedFAN. http://www.almico.com/speedfan.php
I´m no programmer and hope these information hand for an implementation in RR.
SpeedFan publishes a Shared Memory area.
Using Delphi convention:
temps:array[0..31] of integer;
fans :array[0..31] of integer;
volts:array[0..31] of integer;
The name of the shared memory area is "SFSharedMemory_ALM".
INTEGER is a 32 bit signed integer.
Consider that these specs were written a long time ago and might change in the future, but, currently, they are working fine ever since :-)
