I've seen many times posts/threads regarding the heat added by pumps to the systems water.

Iwaki pumps are often refered to as adding less heat (percentage of pump use) that other pumps on the market.

How large is the differance between free flow and under the resistence of a system with 2 blocks, a example being a Cascade CPU block and a Fusion GPU block, with 1/2" lines.

If a particuler pump needs to be spec'd, then let's use the MD30rlzt, as it's about as big as anyone would use. Or for a smaller pump the MD15, still strong, but more reasonable.

The MD15 has a 28 watt draw & the MD30 has a 90 watt draw.

Perhaps a short version being: What would be the maximum amount of added heat be from these pumps under a heavy load/resistence?
