WHAT TELLS THE COOLING FAN TO COME ON

2008 Chevrolet Equinox • 68,000 miles

What sensor tells the engine cooling fans to kick on, or should I say what sensor tells the PCM to trip the relays on a 2008 Equinox 3.4 ltr engine? Both fans not running, gauge on dash in red, not steaming, no bells, lights or whistles. I tested the relays and they are fine.
