The Kuhler 1250 from Antec is a dual pump, dual 120mm fan CPU liquid cooler. Performance-wise we're looking at pretty decent numbers, but I feel like a big part of that is simply due to raw surface area and not because the design is particularly efficient. The cooler could perform better in push/pull, but unfortunately we don't test coolers in push/pull due to the extremely limited number of cases that can accommodate that configuration, particularly with this radiator & pump combination.
