Cooling German rad connector question

Hi,

Long time lurker, first-time poster with a quick question;

I'm just about to buy a German radiator that is listed as having "G1/4inch" connectors.

Would anyone happen to know what the UK or USA equivalent size/pitch is?
(With regards to buying the appropriate barb allowing for connection to 1/2" ID tubing).

 

Don't buy that german stuff. Not that it's bad quality but those germans have the nasty habit to use 1/4" ID tubing (8/10mm ID/OD). It's even smaller than 3/8" (10/12mm ID/OD) tubing and certainly smaller than 1/2" (12/16mm ID/OD).
Unless you buy also german stuff for the water blocks and the rest of your stuff you will have to adapt the 1/4" tubing to 1/2" tubing.
This means your rad will represent a big restriction in the 1/2" loop...

G1/4 is an international standard.

As innovatek use on their equipment.

You can get any connector with G1/4 (also 1/4" BSP(T)) and use the tubing you want.

 

I know.
But AFAIK those 1/4" BSP connectors (whether they are hose barb adapters or simply male-male threaded adapters) have an ID of about 8mm which still represents a restriction when used with 1/2" tubing.

That's also why I use 15mm OD (13mm ID) copper tubing instead of 1/2" hose barbs (about 10mm ID) in my WC setup...

Innovatek Watercooling throughout... works a dream!

 

Hi nightic. Welcome to Bit-tech.

G1/4 is a BSP Parallel equivalent.


^ These are the largest barbs I've found available to fit them at 15mm OD.

Turbokeu - do you know something about his loop we don't or are you just anti-German products for some reason?

 

I can only guess that he is basing his recommendations on the following comment:

8-ball

 

Thanks for the replies guys.

It would seem a mix-and-match of the German and large diameter stuff isn't best advised but I'm having some difficulty appreciating the reasons why the (usually) German companies have settled on their particular design philosophy.

I've posted over at Pro-Cooling with regards to this if anyone would like to have a read:

Pro-Cooling thread

 

High flow doesn't always equal high performance. A lot of these new high flow blocks only really work well with powerful pumps. Which is all good and well until you introduce some kind of flow restriction, such as a GPU block.

Low flow watercooling doesn't have this problem.

 

Okay, I'll admit I was baited somewhat by the opening line

I was in a hurry to get to a medical examination appointment and posted in haste. Apologies for any offense conveyed.

You'd be amazed how diverse various German watercooling companies' products can be. It's not all low-flow & narrow tubes, you know.
As it happens, I received a mail from nightic prior to this thread being made and have requested more details about the loop in question.

Will check in on the Pro-cooling thread when time better permits - looks like a nicely thought out post from what I read of it, nice one nightic.

 

Well, the loop I had in mind (since changed) would have entailed all 1/2" ID fittings except for a typically German rad (AirPlex/HFT - G1/4 native connectors).

[The rad being specified due to the ready availability of off-the-shelf external mounting kits etc].

The Pro-Cooling thread will hopefully explain in greater detail the difficulty I'm experiencing in understanding why one system type is chosen over another when they are essentially so contrary.

PS - Apologies to all the German companies out there not making the small tube/low-flow gear

 

Indeed...

This should prove interesting...

lol. You've really let your self into some fun there.

 

well, I was bored of pre-conceptions like the above.
What else should I do?

 

I'm looking forward to see how this turns out....
