I usually keep it to auto, I mostly shoot raw and at lowest ISO (lowest ISO number has lowest noise) anyway.
There is also dark frame noise reduction - this works a little differently and I keep it "on". What this does is, after a long exposure, it takes an equally long exposure with the shutter closed, and then subtracts that noise from the photo it just took. So its useful for long exposures, if you don't do the dark frame subtraction yourself, with special software.
