Thanks, I thought it was a good idea. And by adding the gauge to you'll be able to tell what your temps are with and without fans. I thought over the idea of getting a larger HE for more volume, but in my opinion you'll just have more volume of coolant at the same temps. This is were I got the fans:

This is were I got the Gauge, mount and sender unit, the sender had to be special ordered for a two wire application:
