I claim the ornamental design for a cup holder for temperature control, as shown and described.
FIG. 1 is a perspective view of our design;
FIG. 2 is a front view of our design;
FIG. 3 is a rear view of our design;
FIG. 4 is a first side view of our design;
FIG. 5 is a second side view of our design;
