Howdy everyone,

I was lying on the beach the other day while on holidays dreaming of water block design (doesn't everyone spend their spare time dreaming about wb design?)

anyway, has anyone tried a motor driven impeller inside the water jacket hard up against the block to distrupt/reduce the boundary layer?

Seals for the motor shaft would be easy for all those thinking about water leaking, i'm imagining a pair of double lipped shaft seals on a 10mm od shaft. I'm going to try the with a delrin impeller.

Worth a try, can see one benifit being very small pressure drop if it works.

Regards,
