I'm about to replace the flex fan currently installed on my V8 which has a custom-built aluminium radiator based on HQ dimensions (61.5 x 36.5cm core).

I can't decide whether to fit one large thermo fan or two smaller ones. I have found a 14" fan from AeroFlow that flows 2000cfm.

And then there is the control unit. The simpler the better, such as the 2-wire senders for oil coolers, but haven't found one for radiators yet.

Any advice welcome.

Cheers, pb
