Answer
If the temperature is too low (below $55$ degrees celsius), the interaction between the oxalate and the potassium permanganate will move too slow as to be used as a practical lab experiment.
Above $60$ degrees celsius, oxalate acid begins to decompose, so its important to stay in this range.
