The more precisely momentum is known, the less precisely is its position known and vice versa. As for how temperature affects these measurements, the velocity of atoms and molecules isnt a sharp peak but a probability distribution whose maximum shifts toward higher velocities as the average temperature increases.
IIUC extremely cold substances turn into so-called Bose-Einstein condensates because their temperature (hence speed) is so tightly controlled that their location becomes more “spread out” in terms of probability. And you can’t fix its location without raising the temperature.
