We study quantum Hall systems (mainly the integer case) at finite temperatures and show that there is a novel temperature dependence even for a pure system, thanks to the `anomalous' nature of generators of translation. The deviation of Hall conductivity from its zero temperature value is controlled by a parameter T0 =πρ/m^∗ N which is sample specific and hence the universality of quantization is lost at finite temperatures.
