Does it not run a bit cold with two fans on?
Only if you leave them on

Serial connection is a no go. You will only have 6 to 7v across each fan.
I got this idea from the 3rd gen forum, where they've talked about doing this with the LT1/LS1 fans, with some people that have done it. What's wrong with 6-7V at the fan?

I'd get a dual fan thermostatic controller...
Budget=£0. I can work with what I've got which is wires and relays. (Plus a temp sensor or 2).

You should need a fan at all for normal running and it should only need to kick in for sat in traffic, mega hot day, or with aircon (which I'm guessing isn't fitted)..
Correct. Currently it's setup in parallel, with both kicking in/out based on the temp sensor in the head. Works pretty well (or it did when the car was driveable
) There is also a manual override switch.

Series setup is also a no go from the point of view that if you lose one, you lose both, having them wires in parallel at least gives you some reassurance you're not about to lose all your cooling.
Understood, but that's where the manual over-ride kicks in. The relay setup is set to switch between serial and parallel.

That said, if you've stuck modern fans in an old car, maybe it is time to modernise the electric too. I would imagine a 2nd gen was designed to have an engine driven fan not an electric one, so using the rule of diversity, maybe the system just can't cope with what you're expecting of it?
Agree/disagree. There is a reasonable system and it works OK, I'm just looking for improvements.
