Engine Fans Not Playing.
Discussion
Possibly the temperature sensor.....I'll leave it to someone else to tell you where it lives, probably in the rad somewhere.
It may be worth locating it and shorting it out, if your fans run then its the sensor, if not then the problem lies with the fans...however its unlikely that both won't work all of a sudden.
There's probably a control box lurking in the nether regions of your car somewhere....again not sure, however I'm sure someone on here knows

It does sound like it's the temp sensor which is located below the shaped glassfibre panel between the fans and the engine.
The panel is held in place by 6 (I think) hex-screws and is easy to remove although you will have to loosen some hoses and the air intake ducts first.
The sensor costs about £15, and is just screwed into place.
Hope this helps.

Good luck with lucky 7!
Don't worry about the fans too much. I had the same concern. Would often get 110 deg on the guage with no fans cutting in. Only after connecting the ECU to my laptop did I notice there was about 10-15 deg difference between the coolant temperature (used by the ECU to control the fans) and what was shown on the dial.
Checked that the fan came on at around 95 deg and all was OK.

Had same problem with sensor, but when plug taken off both old and new sensors still only passenger side one comes on, both fuses and relays checked ok. At least pax one now cuts in at 95 degrees. Anyway should both come on with plug removed for 96/P 4.2 and any further ideas ?

Both should come on when the sensor plug is removed.
If only one comes on... most likley problem is the fan power connectors. Swap them over to see if the other fan comes on. If so the power connector (or fuse/relay is duff). If the original fan doesn't come on, most likely the fan is duff.
I've just replaced the terminal connectors and then wrapped them with self-amalgamating tape to make them water proof.
