ARTCC handed me two aircraft on collision courses at the same altitude! Aircraft X and Aircraft Y were going to lose separation within a few miles of crossing my boundary coming from Denver Center. I called the ARTCC 'controller' and told him to turn Aircraft X 30 degrees left to go behind Aircraft Y. He acknowledged that he would comply. He waited at least a couple minutes before he told the aircraft. The sooner he gave the clearance the better because there was a 100 knot tail wind on Aircraft X and he was going to pick up speed. I feel that the ARTCC 'controller' defiantly waited to turn Aircraft X because the aircraft took so long to start his turn; but this is only speculation.Retrain these people before a midair occurs!
ZMP ARTCC reported ZDV ARTCC handed off two aircraft at the same altitude on converging courses without taking action to ensure separation.
