Well it's just a fitting. If it leaks you will know in extensive 24 hour leak testing. Running it for a year and then tearing it down to inspect will tell you more. It depends what you want to spend. Never said WC is cheap, and not able to source/live in the USA is tough. Get a few, try them.
I use Bitspower rotary 90, the smooth ones, not those hard 90 degree ones. Yea they cost, but watercooling is a hobby, not an economics experiment. You wanna WC? You spend what you need to spend.
Hi, thanks for your comments,
though would have to disagree with something you have said.
No where have I said that 'WC is cheap' as you so put it, yes I have asked if there are cheaper alternatives which does not equate to 'cheap'
I would say I am an average guy, who if can save some money and get a like for like job done would go for it.
Maybe you are in a fortunate position to be financially comfortable, I dont know.
Also have 4 bitpower rotaries in my build (2x90, 2x45) doesnt mean I shouldnt try to save some money.
As you have acknowledged that those outside of the USA have to pay more for certain things would have been nice of you to have shown a little more understanding why some peeps (like myself) are looking for cheaper alternative that are up to the job.
Have been informed by the business that sells the rotary that these will be available after the Chinese New Year, and are as I suspected are an OEM job for them.
Reading in between the lines, it looks that they maybe the same as the EK ones.
I think it fair to say, that the quality of an EK fittings is comparable to a Bitspower fitting.
Anyhow, as you correctly stated onyl through the testing and use of these fittings will one know.
I guess or a knowing head nod. You being an adult you know that doesn't help at all. Sorry.
