good point, good point, but look at it this way.

In a rad, the deltaT is not very large, in relation to the deltaT of a cooler or instance, so the flow rate of water really doesn't make much of a difference since high flow or low flow, the efficiency will be more or less the same. The reason you would want high flow on a rad setup is because it is better for your specific block, since some blocks perform better with higher flow.

In a cooler, however, the deltaT is much greater, therefore the more "time" the water spends in contact with the cooler, the longer it will be exposed to the "greater deltaT", the more efficient and effective the cooler will be. Because of this lower flow rate, you would probably want to pair the setup up with a block that performs better at lower flow rates.


Am i thinking along the right track?
