Aircraft X was eastbound at 37;000 ft coming from Denver Center. Aircraft Y was northeast bound at 37;000 ft also coming from the same sector on a converging course with Aircraft X. The Radar controller took the handoffs on both Aircraft X and Aircraft Y approximately 30 miles inside the adjacent Center boundary and they transferred communications on both aircraft even though they were going to lose separation inside their airspace. The Radar controller immediately turned Aircraft Y 15 degrees left to go behind Aircraft X. Because the winds were from the northwest at 70 knots Aircraft Y lost some airspeed in his turn. If not for the wind direction and the turn by the controller; separation would have been lost. Aircraft Y passed about 6.5 miles behind Aircraft X. I added Aircraft Z to the list of aircraft involved because Aircraft Z was just north of both aircraft; eastbound and at 37;000 ft. The Radar controller had to time the turn back on course with Aircraft Y otherwise separation would have been lost between Aircraft Y and Aircraft Z.Send a team of investigators to ZDV to find out why they are not required to separate aircraft!
ZMP Center Controller reported an adjacent Center controller handed off two aircraft that were converging inside their airspace.
