Abstract
An information handling system includes two or more heat-generating devices and a liquid-assisted air cooling (LAAC) assembly to cool at least some of the devices. The LAAC assembly includes a radiator, first and second pumps connected in series with the radiator. The LAAC assembly further includes first and second cold plates enclosing first and second CPUs or another suitable heat generating device. The first and second cold plates are connected in parallel between an inlet of the first pump and an outlet of the second pump. In this configuration, the serial connected pumps in combination with the parallel connected cold plates provide 1+1 pump redundancy while delivering cold coolant from the radiator outlet to both heat generating devices such that neither heat cold plate receives pre-heated coolant from the other cold plate.
