For Piece of mind
How much bigger should the barbs be?

I've used 7/16" on 1/2" barbs should be fine. It's a bear to get on, but it's solid. Throw some zip ties on for insurance.

7/16" tubing on 1/2" barbs should be used if you don't want any leaks.

Second build using these size, not a single problem.

Good to hear all is well. And yes, do keep a watch on all the connections (I put paper towels underneath and around each connection).

Edit: And yes, 7/16 tubing over 1/2 barbs are great; I've never had a leak that way.

As long as you use distilled water, the chances of actually damaging your board and components in the event of a leak is small.

I've had distilled water ooze (slowly) out of my fittings and form a pool around my CPU socket, NB and DIMM slots. I didn't realize it for at least a good half-hour since I was busy benching. When I did notice it, all it took was a few paper towels, fixing the connections, and everything was back to working condition.

I'm sure being on a tech bench helped since everything is horizontal.

I'm using 7/16" tubing on 1/2" barbs as well. It was a bear to get on till I softened the tubing with some hot water. I can't get the tubing off now without cutting it. So it is very very secure. I still use some zip ties just for added security.

Another leak? Ouch, watercooling is something you really need to take your time with, especially the first time. Sounds like you rushed it a bit. Good luck.

Sounds like this is the way I too should do it then. Are barbs the best way to secure the tubing or are the compression fittings the best? Clamps of some kind should be used with barbs, right? Or are zip ties really strong enough?

this is why the gods invented compression fittings!!
