Yes, as close to absolute zero as possible to reduce thermal noise as low as possible. Multiple, stacked pielter devices, commercially available from dead car/fridge/freezers, can be stacked one behind the other and are quite capable of getting to within a bugs whisker of absolute zero, or -273 degrees.
