Here's what JimF says:

*****************************************************
The fans are supposed to come on at (around) 100C w/ the A/C "off". 107C is a bit high but I've seen a few cars that kick-in at the temp.

If it's a HOT day (90F) and you start the car w/ A/C "ON", the aux fans will come on when the pressure reaches around 14 bar or 206psi. For example, my fans come on at 15bar, apx 240psi. Check MENU#18 about in the middle of the section; the table shows the pressure and temperature kick points for an S car. Yours is similar except you don't have the number of stages (3) that the "S" has.

If the weather is cool, the fans will not come on even w/ A/C on if the pressure is not exceeded. Here in So Cal, my fans don't come at all even on an 80F day for normal driving until the PSI or TEMP is exceeded.
If you want to turn them on at a lower temp, check out my page and the "Cool Harness".

Not wanting to argue - just think that going after the aux fans is barking up the wrong tree in this case.
