Losing faith in EK

3t3P · 24 Dec 2018 at 16:56

I had nickel plate failure on a GTX 470 block which EK dutifully replaced.

Now fast forward however number of years and I have an ek supremacy and GTX 1080 block both in transparent plexi/nickel finishes.

I run EK tubing (made another thread on this a while ago, stickwith primochill if you can) and distilled water with 1-2 drops of PT Nuke and that's IT.

So I noticed the other day there is brown looking gunk around the rubber seal on the CPU block. Almost as though the block is corroding there? Or somehow the plate top mounting screws are rusting?

Then I peak under the GTX 1080 block and see sort of that copper oxide -like deposit on the microfins.

So I don't know what's going on, apart from the radiator I'm not mixing metals, not using weird coolants.

Haven't got any photos (can get some, obviously) but I'm disillusioned somewhat by these findings.

Maybe I shouldn't buy transparent parts

Anyone seen something similar in their blocks?

I tend to do no unecessay maintenance to my loops. From my previous one I learnt I won't use dyes again for it clogs blocks up so went with a pure water build and transparent parts and clear tubing for that ''icy" look.

Seems I'll be forced to do a teardown though

so what IS this STUFF?!

I never realised that with PT nuke. its the PHN/neutral one too. I never saw it mentioned anywhere either

in fact its the first time I ran with it.

I've had a kill coil in the past and pre-mixed dyes.

shame as I wanted to move away from pre-mix everything

Is this reversible? how should I deal with it, am thinking physical strip down rather than putting hope in any flushing agents. need some good clear tubing too at 7/16 ID.

Thanks. I'll need new tubing. Any recommendations for clear, no logos, reasonable kink resistance and small bend radius, that won't leech plasticiser/go cloudy that isn't the EK stuff. 7/16 " ID

Thanks guys so to confirm re the Mayhems tubing if I soak in boiling water (as I have always done and never used zip ties/compression fittings) it will fit over my barbs?

XSPC I used once leeched badly. Primochill is good but expensive, don't mind paying to play but can't get the clear stuff in the UK EVER for some reason.

Cryofuel I'm sure is fine just use the clear one.

Most of us not getting on the the EK tubing

Update:

The blocks are fine both CPU and GPU. Mayhem's blitz got most of it out I think it was plasticiser.

Only think I have to say, which has been noted by others about the Evo supremacy is that the plastic insert has taken on a cloudy appearance. I'd rather it wasn't this way but it's commonly reported and seen in photos.

Otherwise faith in EK restored and have 13 of their compression fittings coming from ocuk to try with mayhem's tubing.

Will be a departure from barbs which have caused me zero problems in 9 years so am a bit anxious!

Went for 10/16mm tubing and fittings.
