    Hello, I want to use a 12v thermostat to control the cooling of my led setup, this is a 4 ft. aluminum setup with two heatsinks.

    The thermostat I want to use is a 12v single probe NTC 10K thermostat, so I thought about measuring the average temperature using a 4 probe setup, 2 series of 2 in parallel, this would result in an average reading of the 4 probes, am I right?

    Thank you.

    Maybe, maybe not.

    If the temperatures are about the same within a few degrees it might work. With wider temperature differences the transfer characteristics (linear or non-linear) would not give a true average.

    Yes, the temperatures would be close between the 4 reading points, I'll give it a try, thanks.
