Energy can neither be created or destroyed, so as long as the object had some heat to it, then it could never cool down to 0k because that initial heat it brought with it would be in the system somewhere. Unless you were to isolate the object, and then remove the energy from the quarantine, then that energy will still be in the system somewhere.

If we're talking absurdly long timescales it would eventually go to absolute zero as it's mass decayed into energy and it released that energy into a form that was no longer accessible or useful but by then it would be a bit of a stretch to say the object still exists any longer.
