and no problems with color noise due to sensor overheating, on d800? i have such problem on my 5dm2
You do get some color noise yes, or more color spots, but that is easy to remove.
Its not really an issue for 4-5 even 10 minute exposure, its more a problem with 30 second exposure with many shots over hours, then I see lots of color noise.
