Recent X-ray observations have revealed a universal temperature profile for the intracluster gas of non-cooling flow clusters which is flat for r ≤ 0.2r₁₈₀. Numerical simulations, however, obtain a steeper temperature profile in the inner region. We study the effect of thermal conduction on the intracluster gas in non-cooling flow clusters in light of these observations, using the steep temperature profiles obtained by numerical simulations. We find that, given 10¹⁰ yr for the intracluster gas to evolve, thermal conduction should be suppressed from the classical value by a factor of ∼10^–3 in order to explain the observations.
