Will this work for a i9 10850k processer socket LGA 1200

Yes. It's LGA 1200 compatible and provides ample cooling.

Will this fit in the nzxt source 210 case?

It will depend on the case dimension, you could double check the actual case and cooler dimension before purchase. My case is cooler master n400 and t4 fits perfectly.

Will this fit in my HAF 912 Midtower case? I have a GTX 770 and a F2-A85V-PRO motherboard as well.

I have fitted my CPU cooler in a Gigabyte IF233 Miditower USB 3.0 Midi-Tower Case ( http://www.dabs.com/products/gigabyte-if233-miditower-usb-3-0-midi-tower-case-86Z3.html?q=Gigabyte%20IF233%20Miditower%20USB%203.0%20Midi-Tower%20Case&src=16 ) and there is about 5mm clearance to the side cover. If your case is wider there should be no problems.
