A cooling controller of a cooling canister is configured to coordinate control of a set of fans coupled with the cooling canister with another set of fans coupled with an adjacent cooling canister. The cooling canister and the adjacent cooling canister include openings that are coupled together that permit air to flow between the cooling canister and the adjacent cooling canister. In some embodiments, the cooling control also coordinates control of a damper in at least one of the coupled openings of the coupled cooling canister and adjacent cooling canister.
