When I bought mine it only had one “pull” fan plus A/C.
I’ve since added a manually switched fan which greatly aids the cooling process. I’m tempted to add another “push” fan on the front like yours. I do think it will greatly help the A/C and cooling in warmer climes, especially when driving around town or in traffic. I’ve often toyed with the idea of adding mini fans into the engine bay to force the air flow! Stupid I know but thoughts just the same! Thought about a vent in the bonnet as well.
I’m all for better air flow through the engine bay.

Russel, this is a Japanese re import so that answer the 3 fan question with it being a hot climate. But I am no nearer in getting them running. the fans do work as I have checked all three with a battery, and all have good earth connections, but no power getting to them when the car is at 100 degrees. I was told that if you remove the connector to the temperature sensor they should run but not on my car !
Any clues anyone ?

When you pull the coolant temp connector what does the diagnostics say the fans are doing? they should normally* both default to "on" which at least shows the ecu should be sending the earth signal to the relays.
Be aware though that as part of my cooling chip* I prevent the fans coming on until the engine speed is over 400rpm, this prevents the fans sapping power from the starter motor on hot restarts. Pulling the temp connector on a cooling chip car won't bring the fans on.
TVR employed this trick on the sp6 cars but i've yet to see it on a factory v8 cerb, but you never know they may have done it on export cars too .. so check on the diagnostics what the fan signal is doing.

Did you build this into an ECU?There is a reason why I ask?

A very clever man worked it out for me many years ago .. 
I would put money on that clever man being you but could be wrongI'm about to send you something by PM that's very simple and you very likely know about it, I don't want to be looking like I'm attempting to undermine your super duper ECU fan control but you may be interested in this for other work although I do doubt it somehow
