At medium 'Hydro Power', the inlet flow is impinging on the base and the cooling is therefore substantially improved. At high 'Hydro Power', a lot of the applied 'Hydro Power' is being used in maintaining eddies as shown below in red.
The outgoing water has to fight it's way past the eddies and the jet and a lot of the applied 'Hydro Power' is wasted in generating turbulence that is of little benefit for cooling. Also, warmed water from the eddies gets mixed into the jet on the way down.

There is a way around this that I have found. Keep the tip of the jet closer to the base and the depth of the pool should be roughly the same height of the opening of the jet. That keep those "eddies" in check. Then you will start to see an increased benefit for cooling. Then again swiftech can't predict what pump a customer will use with the broad spectrum of pumps available.
I like to see BillA test nozzle diameters from 1/4 to 1/8 and their height in a block plus find a way to take up space inside the block to keep the water from pooling.
