Yes. I have run my EA82MONGREL for years without the factory water temp gauge.
Instead I use two metal temp gauges, one purely as a high temp alarm set to 96° C
They are simple, cheap, Chinese made and sourced 12V aquarium digital units with switching for alarm as I first mentioned, the second is my visible in digital numbers and also set to turn both fans on at 92°C metal temp
I used to run separate fan switching so I slow traffic just to manually turn one on, but two at same time have been working well, they cycle on and off pretty quickly
