We obtain explicitly the minimal possible temperature $T_{\\rm min}>0$ reachable for the two-level system. The minimization goes over all unitary dynamic processes operating on the system and reservoir, and over the reservoir energy spectrum. The minimal work needed to reach $T_{\\rm min}$ grows as $1/T_{\\rm min}$. This work cost can be significantly reduced, though, if one is satisfied by temperatures slightly above $T_{\\rm min}$.
