I don't like groove mount either. For the Smart Effector, E3D makes us a modified heatsink with a screw top:
E3D has said that they are going to offer this heatsink variant as a standard option sometime in the future.

Here's my approach:
machine down the lowest heatsink fin to 13mm and fit it on top of an aluminum effector. The direct drive extruder is optional...

The shape of the heatsink fins isn't optimal for good water flow. The main stream will just take the shortest path.
I'd cut out a small gap in every other fin, so the water has to flow through a zig-zag maze.
Watercooling a single extruder isn't worth it except you'd build it extra small. But on multi nozzle extruders it helps a lot to prevent oozing. Water chills down the unused tool faster.
@andornot The cycloidal extruder isn't my design, but I was the only one, who built it from aluminum and POM. The main problem was the slower retraction speed and the weight in combination with the Traxxas rod ends. I will give it another try, when my compact carrier Delta is suited with Mag-arms. ( No more collisions between motor and rods )

I agree with the "shortest path logic"
But the hotter liquid will be on the upper side of the heatsink, no?
and the heat will be transmitted to the whole liquid?
I was looking at a way to make it "maze like" with cold solder to block the path and dremel to drill some holes.
But because the watercooling is overkill, i can live with an unoptimized part.
The second thing is the load loss. I'll use a little pump and a maze would become harder to pass through.
For me, the main idea was to have fins to increase the surface.
The coldest liquid will be pushed in front of the lowest fins, it should be nice.
The volume of liquid in the hotend will be 4ml
With the smallest pump found (300l/h), and 50% loss,
I'll still have 4cl per second from the pump. so the heatsink will receive 10 times his volume.
One of my solutions was something like that
14 x 25 x 17 mm
But this solution is way to much over engineered. There were no real need to do it.
So I prefer to use the E3d hotend and modify it.

The MG08 was made to over-kill...
For the tubes, the number of tubes depend of the pump's flowrate.
We could simply use a tube like that:
the heatbreak (vertical) goes trough the tube. (horizontal)
With a sufficient flowrate, this solution is possible.
