Could you double-check your engine size, please? The 3.5L was offered in earlier years but may have still been available in 2010. It would be a pushrod engine. The 3.6L is a DOHC engine that is quite a bit different.
You can pop the hood and check the engine cover. If it says VVT then it'll also say 3.6L. If not, then the emissions sticker will reveal the engine size regardless of any engine decals.

Also, please include whether you have the 4-speed or 6-speed transmission. That may help others to help you as well.

Now, on to offering some input.
The radiator fans are designed to run at 2 speeds, lower when less cooling is needed, and higher when more is needed or when AC is turned on.
With that expensive reader, pull up the actual coolant temps and read them, possibly even putting them on a graph as you drive, and then later review them for any signs of issues.
My 2011 3.6L temp runs right about the middle of the gauge, but you have to understand that the gauges are not directly driven by input from the sensors. The BCM receives those inputs and then tells the IPC where to point the needles. It interprets them to some degree to provide useful data to the driver. If your engine is overheating, believe me, you'll get a warning and a light. If it gets too hot, it'll put you in limp mode to help preserve the engine. It's made of aluminum and doesn't handle being overheated very well at all, not like iron can.
