I wanted to go with a pwm fan system, so I spent hours gathering the info.
In the end, using a fan/controller that is a mish mash of parts from other cars, I decided that the Delt Pag fan and controller was about as economical as cutting / modifying, chasing a controller and plugs, etc.

Several nice features include very thin profile @ 2.65". flat mounting with 4 screws, plug/play set up.
It will be mounted on the back side of the core support with the x flow rad in ft.
With the use of the Vette accessory drive, there's plenty of room for air intake tubing.
Pics when it arrives and is mocked up.
Here's the system: 16" Brushless Fan Kit | deltapag . About $450 shipped.

That's a very nice set up.

I used a Jeep Grand Cherokee 19" fan installed on a flat sheet of aluminium. With the crossflow mounted to the front of the core support, the fan sits mostly 'within' the unmodified core support and only intrudes into the engine bay 0.75" on the perimeter, and 1" at the centre of the fan.

And I used this to control the fan;

The stock E38 LS controller provides low and high speed outputs; low operates the fan via the controller (set at 50%), high operates the fan directly.

Yes there were relays and plugs to sort out, but I like that it doesn't intrude far into the engine bay, and for around $120.00 all up, it worked for me. It's been this way for over 3 years now, and works perfectly.

The controller, relays and other bits are hidden behind the hood hinge, so it looks quite neat, well to me anyway lol.
