1. A water cooling radiator, configured for liquid coolant to flow therethrough, comprising:
a first radiator having a first radiator thickness, comprising:
a liquid tank including an inlet chamber, an outlet chamber, and a first dividing panel, the inlet chamber having an inlet port, the outlet chamber having an outlet port, and the first dividing panel separating the inlet chamber from the outlet chamber;
a first liquid return tank defining a first return chamber;
a first inlet radiator portion disposed between the liquid tank and the first liquid return tank, the first inlet radiator portion including at least one first inlet heat dissipating fin and at least one first inlet pipe, the at least one first inlet heat dissipating fin having a first inlet fin pitch, the at least one first inlet pipe in fluid communication with the inlet chamber via a first inlet fluid input end and in fluid communication with the first return chamber via a first inlet fluid output end, wherein the at least one first inlet pipe is thermally coupled to the at least one first inlet heat dissipating fin; and
a first outlet radiator portion disposed between the liquid tank and the first liquid return tank and adjacent to the first inlet radiator portion, the first outlet radiator portion including at least one first outlet heat dissipating fin and at least one first outlet pipe, the at least one first outlet heat dissipating fin having a first outlet fin pitch, the at least one first outlet pipe in fluid communication with the first return chamber via a first outlet fluid input end and in fluid communication with the outlet chamber via a first outlet fluid output end, wherein the at least one first outlet pipe is thermally coupled to the at least one first outlet heat dissipating fin; and
wherein a first inlet temperature of the liquid coolant at the first inlet fluid input end is greater than a first return temperature of the liquid coolant at the first outlet fluid input end, and
wherein a pitch measurement of the first inlet fin pitch is greater than a pitch measurement of the first outlet fin pitch.
