Can fire ever burn at a temperature that can be considered cold?

Well first, lets get a little technical and understand that "fire" is a byproduct of a process called combustion (type combustion into google to get all sorts of techie stuff). The bottom line is NO. The reason is because combustion and its temperature rely on the internal energy of the material that is combusting (burning). Hydrogen is has the smallest enthalpy, so it is what we should look at first. The combustion temperature of hydrogen is about 550 degrees Celsius. Which is far from what you would consider "cold". Since it isn't possible to find an element more basic and with a lower enthalpy than hydrogen, this is where this particular journey into the science of combustion ends.
