1. A cooling circuit for cooling a computing system, the cooling circuit comprising:
a plurality of cooling modules arranged in parallel, each cooling module including a cold plate having a cooling conduit passing therethrough, and a pump fluidly coupled to the cooling conduit, the plurality of cooling modules including
a first cooling module having a first cooling conduit with a first inlet tube and a first outlet tube; and
a second cooling module having a second cooling conduit with a second inlet tube and a second outlet tube, the second inlet tube being adjacent to the first outlet tube; and
one or more valves fluidly interconnecting the plurality of cooling modules, each of the one or more valves, when turned on, fluidly connecting the cooling conduits of any two adjacent cooling modules, the cooling conduits flowing cooling fluid independent of each other when the one or more valves are turned off, at least one of the one or more valves being a single four-pass valve having four ports that include
a first inlet port fluidly coupled with the first outlet tube to receive cooling fluid flowing through the first cooling module,
a first outlet port fluidly coupled with the first outlet tube downstream from the first inlet port,
a second inlet port fluidly coupled with the second inlet tube to receive cooling fluid flowing through the second cooling module, and
a second outlet port fluidly coupled with the second inlet tube downstream from the second inlet port, the second outlet port being in fluid communication with the first inlet port when the single four-pass valve is turned on to flow cooling liquid between the first cooling conduit and the second cooling conduit.
