GPU Waterblock Question.

post #1 of 17
Thread Starter 
I'm about to order a gpu waterblock for my 6950 but had a quick question, the water block will have the standard 1/4 " threads and I'm going to be using Primochill PrimoFlex Pro LRT Clear Tubing -7/16in. ID x 5/8in. OD

So what type and size barbs would I need? as the page where the gpu block is listed gives an option of either 1/2" or 3/8"?

here's a link to one of the blocks i'm looking at.

What kind of tubing clips? The spring steel ones just need to the tabs to be squeezed with some pliers and removed, the plastic ones need a little more finesse. Basically you have to pry the arms apart until they disengage with each other. Good luck, it is a royal PITA.

What kind of clips are you using? If you using zip ties like in the picture, you'll just have to cut them off.

They are nylon hose clamps, kinda like these

http://watercooled-pcs.co.uk/en/hose-clips/1-2-ins-od-clamps/nylon-hose-clamp-for-3-8-tubing-black.html


I get the feeling they will most certainly be a royal PITA to remove!

Looking for a way to remove them without damaging the threading, will probably just cut the old tubing off.

easy they just slide one way. try sliding it sideways to the way you squeezed it together to tighten it, not the whole clamp on the tube but the two pieces of clamp that lock together, sometimes a screw driver helps, they only slide one way so try the other way if it doesnt go

With a bit of work and a small flat bladed jewellers screwdriver you can prise them off, you just have to work at it a bit.
