Message I like that you added a temp display!

Curious what you are using to drive the fan? That was the hardest part for me to get together. I used the MK8 fan though which has a super high amp draw. Ended up using a large mosfet array.

When I did it, I put the temp sensor after the radiator output so I could read both engine temp and radiator outlet temp, the idea (and control strategy) would be to capitalize on the Efan setup and vary the fan speed based on the cooling efficiency of the radiator. I.E. when there was enough airflow for the radiator to cool the fluid without assistance of the fan, the fan speed would dial down progressively. I remember having tons of data, charts, graphs to get everything setup just the way I wanted.

Something to consider.
