Sequence Dart users?

[Delphinus]

How hot does your Dart pump motor get? Mine gets insanely hot. There is no heat transfer to the water it pushes at least but the pump motor is way too hot to the touch.

I keep reading that this is sort of normal but is it really? I really don't like how hot this pump runs. I even put a fan on it blowing laterally across the core, since the motor fan itself doesn't seem to do much by itself .. but even with that it doesn't seem to make much difference, it's still dang hot.

So .. is this really normal?

What are good alternatives to a Dart these days?
