Wouldn't the automotive one work up to and slightly above the
boiling point of water ? The Thermaltake one might not be designed
for that usage. The water cooling in the car, might also be under
pressure.
The temperature sensor in my car, appeared to have been a simple
resistive unit. At least the tech working on my car, tested it with
a multimeter, to see whether it was in the right range or not. It
turned out to need replacing.
The Thermaltake could do just about anything it wanted. It could be
a resistance to ground. It could be a voltage sender. Any amount
of active circuitry could be in there.
I suspect you'd have a few parameters and properties to check, before
making a substitution. You could end up with a large puddle under
the car if you don't :-)
