Tube size
Larger flows easier and faster with less pressure.
look at area of circle vs radius. Volume off a tube vs Radius.
larger tube has less effect due wall friction on flow.
Primochill Primo Flex 1/2" inner 3/4" outer is what I have.
Rad have 1/2" G1/4 threads most of the time.
I was not as careful as should have been in my first water cooling.
Soon I Will try again
