Does changing the fat content in milk used in an ice cream mixture change the temperature or thickness it reaches after 10 minutes in an ice cream maker?

The purpose was to determine the effect of the percent of fat in milk used to make ice cream on the temperature and thickness the ice cream was after ten minutes in an ice cream maker.

4. The pan was removed from the heat and the mixture poured into Tupperware.
5. Then 1 of cup cream and 1 teaspoon vanilla extract were mixed in.
6. The Tupperware was put in the fridge over night.
7. An instant read thermometer was used to make sure the mixture is cooled to 1.6º Celsius (35º Fahrenheit).
8. The mixture was poured into the core of the ice cream maker and stopwatch was started.
9. The ice cream paddle was stirred three times, every two minutes, for ten minutes.
10. After ten minutes, the ice cream was stirred twice with a spoon.
11. Then the temperature of the middle of the mixture was measured with an instant read thermometer.
12. Right after taking the temperature the 2 euro coin was dropped in the middle of the mixture. The stopwatch was used to time how long it took for the euro coin to completely submerge, or until no part of it could be
