Informal liquid cooling setup spring clean discussion

Hi guys

Just got back from extended work travel and now on a public holiday so I decided to service the watercooling loop on the gpus.

Pulled it all apart, drained it and flushed it with warm tap water and then let it dry.

Replaced all hoses.

Remove, rinse and wash dust (there was heaps) from fins.

Replace all and fill with distilled water only.

Water was very clear.

After air is bled, it looks pretty neat.

Tomorrow im putting in some propper watercooling liquid (Fesser). These next few days will dissolve all the free ions and crap into it, (flush) and then tomrorow Ill replace it again with Fesser.

Interestingly, at this stage, I get max 63oC (delta 24) ambient 20oC. Sounds high, but its 2 x 580 @ 890MHz (delta 95MHz) at 1.1V running Heaven maxed out (all settings max at 1080p). At that point it gets 78FPS.

CPU at 4.6GHz at 65oC at 100% load high heat (prime95) @ stock voltage.

Im pretty happy with that. Id love to include another 240mm rad, but hey, the 600T isn't a large case.

Ill be interested to see the temps do on Tuesday when i put 'legitimate' coolant in it to see what will happen.

Just washing the CPU RAD in water to remove dust etc reduced temps by 30oC. Not as large drop for the GPU rad, but it only has water in its loop. So im expecting a bigger drop on Tuesday.

BTW, it leaked twice. Didn't kill anything tf.


*edit* im now running Prime95 at high heat AND Heaven at max settings as above - no change in temps or performance interestingly. Damn it takes a lot to slow a 2600K at 4.6.

With 580s maxed and 2600K maxed as above it drags 700W from the wall (not including monitor). You can see how much overkill the AX1200 was, but I was, and will probably in my next upgrade include a 3rd 580. I originally had the third, but realised at that time did nothing for game as no games really saturated the 580s in SLI. Tri SLi needed around 900W, making a 1200W quite a good fit.

Nice setup man!

1. I'm pretty sure you don't need both bridges connected.
2. There isn't such a thing as a PSU that's overkill.
3. It might slightly hurt the flow but I think a 90o out of the bottom card would make the loop look nicer.
 
Yeah you're right. Couldnt be bothered though. But I think I will put a draintap at the bottom there so its easy to drain.

The extra bridge increases performance of around 5% would be my guesss. Its free so yeah. Actually on that topic, when I put it all back together, i was getting green screens. Replaced both SLI bridges, sorted. Funny that you brought that up ;)

Never knew that, very weird that it would work that way.

I was being picky about the adapter just because how big of a loop that bottom hose goes on.

Overall good stuff man. When is the 3rd card coming?
 
Update

Done. Runs at 580SLI 906MHz 98% 1.1V at 69oC.

Coolant in. Amazed at crap that came out with flush.

Temps dropped 20oC for whole process.

Same for CPU with indigo extreme.
