A/C Fan.

I had my a/c thermo fan hard wired to a switch on the console so I can turn it on whenever.
This fan only comes on if the a/c system gets to a certain pressure activated by a sensor.
My clutch fan failed on a long steep hillclimb last year and I came very close to cooking the donk so I thought it would be a bit of extra insurance.
A lot of the US guys have done this mod as they crawl along in very hot/dusty conditions.
On a club trip last sunday it was 34 degrees and very dusty, my temp gauge usually sits on half no matter what the conditions. I ran the a/c fan most of the trip and it kept the gauge around one third perhaps a bit more. As soon as I turned it off the gauge went back to halfway instantly.
So it does provide some extra air flow.
It only cost me $60 so I think it's a good/cheap mod utilising existing equipment.

Details please, I'd like to try that!

Well when they did my dual batteries I got them to hardwire the rear accessory socket to the second battery I also asked them to hard wire the a/c fan (located in front of the condensor) to a console switch. It's only a small electric fan (about 200mm diameter) and they ran the wiring from the fan through a relay to the console switch.
