The RD-30 is nice, but it is somewhat over-powered and hot (has too large of a heat dump) for anything short of a tri-fan radiator to deal with.

The RD-20 is a much better balanced pump as far as water-cooling use is concerned.

I have the 24v RD-30 here, and I get my best temps with the RD30 when it is run at 17-19v, rather than at its full 24v, and I have a 24x30cm radiator cooling the water (although with two quiet fans).

Internally the RD-20 is indentical to the RD-30, and the RD-20 @ 24v runs pretty much like an RD-30 @ 20v.

So again, the RD-20 is the better balanced pump to be targetting here, and not the RD-30.

What about the Panworld PI 20? Supposedly slightly better specs than RD20, same heat dump, just as hard to get and the size of an MCP600.
