Electric fans operating temperature range

I recently bought a brand new 2.4L 4X2 Compass. I am having some doubts regarding how the electric fans work/should work. Does anyone know at what temperature should the electric fans start to work? Are there 2 different speeds depending on the temperature? How does the car determine when the fan has to stop? Is it only based on temperature or is it also based on time? What temperatures are the ones activating the fans, is it only the refrigerant fluid or does the transmission temperature also make the fans start? Sorry for so many questions all together... I love my new Compass, but since it provides a lot of real time data around temperatures I am very interested in checking that everything is working as expected. I have found 2 or 3 times the fans working at very high speeds with the refrigerant fluid temperature at normal figures.

Thanks in advance for your help!

Fans turn on at "X" temp and turn off at "Y" temp, time is irrelevant. Also its not refrigerant fluid its coolant
