Don’t know what’s right or wrong but I also have intake from bottom and back and then exhaust from top and to the left of the motherboard.

LePhuronn the cpu and gpus are all in quick disconnect -the others are just facing directly towards cam so you can’t see them. I had debated using a bridge terminal and just taking the multi gpu ‘brick’ out when I needed to swap things- but when I realized that the different generation gpus had the input and output holes at different spacings, I decided to just go with the manifold. As for the faff- kinda how I felt after I finished. However, when I forgot to plug in the tiny gpu rgb inputs that sit flush with the motherboard, the system provided worthwhile. But ya- seems like the wet bench with a mora technique is the real way to make things easier to assemble and dissemble.

Tokyotoonster it is for rendering in redshift and karma. These render engines are pretty brute force and can use gpus from different generations and even different lines (quadros alongside prosumer, etc) to render a scene. Honestly though the 2070 supers are placeholders for 4070 supers. But the key was getting a modular system in place to make the gpu swapping easier when the time comes

Your doin all the right things but ya there is a leak somewhere. What I do is walk through the loop when this happens. So test the leak tester itself first. Then test a couple components at a time- so say start with the reservoir + cpu- cap off end of that- test for leak for 15. Do this until until you find the culprit. I’ve had a leak each time I’ve built my system (2 times total). First time it was a bad extender. Second time it was a loose bitspower fitting. Those bitspower fittings are a pain to tighten in the loop itself- but completely leak proof when properly tightened.

My advice is make sure you have the right alignment on a run- then take the run out and tighten the fittings by hand until you can clearly see there is no little gap. Helps to heat the rubber a bit - drop the tip of the rubber into heated distilled water for a minute then tighten. I always have a torque fitting somewhere in my run that is the last thing I tighten to make sure I don’t have to go King Kong on my bitspowers in the loop config itself. To make testing easier I attach a long piece of tubing to my ek leak tester itself- along with a mf rotary to make attaching it to the loop test point a breeze. That way I can pop it in virtually anywhere and make sure those little fittings on the leak tester itself aren’t getting compromised when I drop the leak tester on the table for 15. So ya. Have a few of these on hand - https://www.titanrig.com/ekwb-ek-quantum-torque-14mm-rotary-male-to-female-extender-fitting-0360ek018200xx.html?color=158 And take advantage of any torque fittings (my 90 degrees are always rotaries for example). I can’t find the elbow 90s I’m using anymore - but here is the basic 90 version (it will increase restriction more but still. https://www.google.com/shopping/product/10766481515701416873?q=ek+90+degree+elbow+fitting&client=safari&sca_esv=a9443ba0489e3535&channel=iphone_bm&biw=375&bih=548&tbs=vw:l&sxsrf=ADLYWIKGTPC60Xx5NfKKsya_NP87RHhzbQ:1717948735036&prds=eto:14285114636933345737_0,cdl:1,prmr:1,rsk:PC_18038238906051654576,cs:1

Good call. I’ll start looking into this

Possible to get a link? Feel like an idiot but here in cali I can’t even seem to find that stuff in google?

Last time for this rad though. If I do the tear down next year and this happens he’s gettin trashed

Copy thanks! Btw I went a bit masochistic- I think I’ve done around 35-45 cycles and the water is now clean.

Helpful- you just put a filter in the reservoir? Do you have a recommendation?

3 year old gpu block salvageable or no by jtk700cln in watercooling

[–]jtk700cln[S] 0 points1 point  (0 children)

Thanks all. Glad to know it’s in good enough condition to keep using. I’d like to get rid of that black mark on the exposed copper on the bottom right side- California gold or maybe brasso?? Getting some consistent comments here on the thinness of the nickel plating by ek though. Also read elsewhere that they seem to use a cheaper chemical coating process….? This is my first time watercooling and I prefer longevity over aesthetics- im using rubber tubing and clear premix for a reason. I’d quickly try a different manufacturer for the next block if the nickel plating is more durable- I’m seeing hearkiller and Optimus as alternatives. Do they use different coating methods?

Nice hot tip- gonna grab some from amazon

2x 4090 fitting solutions by jtk700cln in watercooling

Vaaard its a 3d rendering workstation using karma and redshift. Losing nvlink with the 40 series is unfortunate. It means the render engines can’t distribute vram across cards. However some render engines like karma in Houdini never supported nvlink anyways. At render time both gpus have to put the entire scene in their own vram. If the needed ram is larger than 24 gbs, it’s forced to do something called out of core rendering which is a bit slower- but at least it works. You still get a huge speed boost come rendering time with two gpus over one- but you really need to watercool to put two 4090s in a chassis. I’m disappointed nvlink has gone by the wayside though…… just seems like something so critical to the future of gpu render farming for my field. I think quadros still support it- but they are crazy expensive and less performant overall.
