1. An equipment cooling rack device, comprising:
a cooling cabinet, having a cooled area, the cooling cabinet holding multiple different servers to be cooled in the cooled area;
a cooling structure, coupled to the cooling cabinet, and providing:
a cooling coil, receiving cooled coolant therein, and receiving air to be cooled;
a supply fan, located on a first side of the cooling cabinet, and forcing cooled air, that has been cooled by the cooling coil, into the cooled area, the supply fan facing in a first direction to force the air into the cooled area;
a return fan, located on a second side of the cooling cabinet opposite to the first side, and pulling heated air that has passed through the cooled area and has passed over the multiple different servers, and forcing the heated air over the cooling coil, the return fan facing its output in a second direction orthogonal to the first direction;
a controller, which produces outputs that adjust an amount of air that is blown by the fans, and also adjust an amount of coolant that is supplied to the cooling coil;
a thermal imager configured to determine information indicative of a temperature of the cooled area of the cooling rack; and
wherein the controller controls the amount of coolant that is supplied to the cooling coil, and controls the amount of air that is blown by the fans, based on the information obtained by the thermal imager.
