Let me restate what I meant

High flow is good, if you have a waterblock and radiator that can take advantage of it.

However the guys that change from 3/8"ID to 1/2"ID on a 1/4"NPT port, dont get any higher of a flow rate. It may go up slightly just because of the added volume in the tube. But other than that not much.

The thing that needs to be done is move to a 3/8"NPT port. The problem is the maze designs that I have seen can't accomidate a 3/8"NPT port.

Also I use(and sell, although this is not meant to be a promotion) Push-in type fittings. These grip the outside of the tube. For example with a 3/8"NPT port and 1/2"OD(outer diameter) tubing, I get a unrestricted 3/8" flow. The guys with 1/2"ID tubing and 1/4"NPT barbs get restricted down to a 1/4" flow.
