SPCR

Hi all.
I have been recomendet a MasterKleer - 15,9/11,1mm (7/16")
Is this too small. Should i get a bigger one. What size.
It is for the following parts:
1 XSPC Delta CPU V3 – Acetal.
2 XSPC RX360 Triple Radiator.
Swiftech MCRES-Micro Rev.2.
Laing D5 pump.
aquagratiX - Radeon HD 4890 (RV790).
Hope you can help.
Morten.

10 and 12 mm inner diameter is usual (some systems use 8 mm). It depends for some part what the connection of the other parts are, otherwise you have to use adaptors or exchange the barbs.

16 mm is quite thick, make sure the loop doensn't have bends which are too tight, or the tubing might kink.

With a good pump the tubing doesn't matter much: the most pressure will be lost in the waterblocks and radiator anyway.
From what I know, a D5 connects to 12 mm ID tubing, it might be very hard to fit 11,1 mm to it (or the tube has to be very flexible).

Thanks spookmineer for the heads up on the 11,1 mm could be to hard to fit to the Laing D5 pump. I will find another tube )12 mm ID). But why not go all the way up to Dimensions:19mm outer diameter; 13mm inner diameter, or are they to difficult to work with.

The fatter the tube, theoretically, the better the flow. In practice it makes very little difference however. Similarly, the fatter the tube, the harder it is to bend and work with.

That said, whatever ID size you choose, I would try and get the thickest walls you can. I found it much easier to work with thick walled tube.

You can fit 7/16 tube over the 1/2 fittings on a D5.... but you will likely need to use some hot water to soften the tube first.

Thanks for the advice ascl. The bit about the thicknes of the wall was unknown to me.

The thinner walled stuff seems to kink much easier.

I personally went for 1/2inch (as much as I ALWAYS use metric measurements, too much info is in archaic imperial and converting all the time is more confusing than just dealing with inches) ID (3/4" OD) tube over 1/2" fittings. In retrospect I may have used a thinner ID, as it would have made some of the routing easier.

I will go with the 1/2inch as well. I to always use the metric system. The other measurements have always confused me. We don´t use them in my country, except for some few lumber measurements and such.
