TCS radiator question

[BDA]

This is the adjustable fan controller I got (https://smile.amazon.com/gp/product/B000CN4XZI/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1). If you want, you can install a switch and override the controller. The thermostat is electric so you don't have to worry about breaking a capillary tube. It slides in between the radiator fins. You can hardly see it. Before that I had one similar to the one GavinT mentioned. There's a small rubber seal that fits between the bib on the radiator and the hose and "squishes" around the capillary tube. It actually works fine but I prefer the one I got from Amazon.

I used the Haydon digital fan controller and their temperature sensor screwed into my aluminum radiator via an adaptor bushing, which I made.  It works very well, with a soft start, variable speed and it integrates with my ac unit.

I checked the switch I ordered and it is a 95 opening and 90 closing.  I guess if it doesn't work well I can change it or use it as a plug and get the unit that goes in the radiator fins.

Should be ok.  It will get hot on the gauge before the fan will kick in.
