So if you are planning a low restriction, high fliw loop, the D5 is better equiped to deal with it.

Both the DDC and the D5 probably produce close to the same amount of heat. But the D5's metal volute allows it to better deal with it's heat output.

This is why a DDC will feel warmer to the touch.

Now some guys may feel the DDC is a better pump because it doesn't dump as much heat into the loop. Depends on how you look at it I guess.

Again, there are 2 type of DDC pumps, you can not just group the two together stating that both require air cooling, The DDC-1 series is 10W and remains cool to the touch just like the D5.
The DDC-3 series requires the heatsink on the base. All of the Laing pumps have the stainless steel impeller base. Sure, the D5 dumps it's heat load into the coolant, thus the loop needs more fan energy and RAD cooling to compensate for the added heat load.
