I live in New York it's currently 29 degrees outside. I haven't started my car in alittle over 4 hours and this is what I come to. The engine had not over heated. Checked my antifreeze levels already and my fan is working. Anybody have any ideas why it is that my gauge reads well over normal temp?

faulty temp sensor at a guess, think there is one in the lower coolant hose

"gauge reads well over normal temp?"... that thing is pegged against the side of the housing. Would the needle spin if not blocked?

So, you started the car cold (4 hours not running) and it immediately reads explosion temperatures? I think if that gauge is showing actual temperatures then you would have other obvious indications.

If from a cold start, then surely it is a sensor or the gauge. There must be another way to check reported temperatures other than that gauge. What sort of OBDII reader might you have? Maybe the gauge got messed up when whoever was making its border red? The BMW manual states about the temperature gauge that "If the lamp comes on while operating the vehicle, the engine has overheated. Switch the engine off immediately and allow it to cool down." This seems to say that it will illuminate (I presume the thermometer icon in the middle of the gauge), which does not seem lighted in your picture, so maybe just the gauge itself?

That's my first guess. Although those fist ones are often off target...

I assume it's a sensor as well I put the red border in about 3 weeks ago now I'd assume if something was wrong with the gauge it would have stopped working a whole ago.

But the red light on the temp gauge was not lit up and my car has not exploded. I'm going to get it on a lift today to find out the problem.

Could be whom ever did the work to put in those color gauge rings might have damaged the whole cluster...

yep I doubt it's a coincidence that gauge rings put on and temp gauge/needle are now broken.
Use the cluster test and see if you can reset the needles with the test. It'll swing all the needles to full and back to zero again. You don't even need a scanner-tool to do it. Search "Cluster Test".
Never know..
