Loop finished, only one leak so far, no disaster...

Michaeljcox24 · 19 Jan 2013 at 21:01

I've finished the loop I posted about earlier in the week. Leak tested it for 6 hours, then plugged it in, and tried a couple of benches. Honestly, if ever need a reason to go over to this, it's because of the drop in temps. My cards used to do 85 and 83 in skyrim after 10 mins.

Now, they max at 45 and 40. CPU temps has also dropped around 10C

However, I don't trust that rotary alphacool right angled barb in the pic, above the bog roll. Had to get some long nose pliers to tighten it, and the joint is slightly under load because of the pipe hanging down towards the drainage point. When I checked the fitting tonight, it had a tiny leak so I had to tighten it some more.

Are rotaries a bad idea. I bought everything else from OCUK except for them. Didn't really know what to shop for so I got these because I thought I might need them at some point.

Other than that, temps are honestly, immense. I really can't emphasize it enough.

Next steps:

- Some LEDS for the raystorm block in red.
- A replacement LED for the back of the res, I lost the one in the box.
- Replace that rotary with a fixed 90 degree elbow?

Leaving rig on now, not putting side of case on till I can trust that rotary.

Alphacool Rotaries suck - fact

Without tools they are near impossible to get tight, I had some rotary thread extenders by alphacool on a radiator, they leaked until I took a pair of pliers to them.

The bitspower and EK rotaries have both been spot on for me though.

Yes. Thats what i found. Impossible to get tight without the pliers. Do ocuk sell the ones you said were better

pgi947 · 19 Jan 2013 at 21:38

Yup

EK & Bitspower

Thanks. If it carries on leaking gonna change it. All the straight fittings seem fine to be honest.

OptimaLnrg · 19 Jan 2013 at 21:44

If it leaks go for the bitspower.

Is that not a strange way to connect the graphics cards?

Michaeljcox24 · 19 Jan 2013 at 21:52

Is it? Someone told me using the two connectors balances the temps out. Not had any probs so far to be honest apart from the leaking rotary.

pgi947 · 19 Jan 2013 at 21:53

Looks parallel flow, should be ok.

Personally prefer serial flow.

OptimaLnrg · 19 Jan 2013 at 21:54

IDK what they meant about balancing the temps out but I went serial to ensure good flow through both. If temps are fine I would leave it as it is.

hyperst · 19 Jan 2013 at 21:55

Well there's parallel and serial but I thought it would best to set the in and out on the same card for parallel to work at it's best

It usually is as its the situation where its not possible to take an outlet from the bottom card (for serial) due to space/tube restrictions.

As long as temps are fine then don't worry about it, iirc some EK parallel bridges are serial and have top inlet bottom outlet

Michaeljcox24 · 19 Jan 2013 at 22:24

Bear in mind this is my first ever loop so if ive done it wrong then its early days and i can always drain and change things.

Monkeyspaz5000 · 19 Jan 2013 at 22:34

As others have said - as long as temps are fine I would just keep as is.

supergluechris · 19 Jan 2013 at 22:38

Btw, If that rotary does leak it will go through the towel and straight into the psu components because you have the fan facing up. Just saying

Michaeljcox24 · 19 Jan 2013 at 22:46

Yes. That's what worries me. Its only a small leak though. No gusher yet.

Monkeyspaz5000 · 19 Jan 2013 at 23:03

flip the PSU the other way round. As long as your case has a bottom intake for it.

Michaeljcox24 · 19 Jan 2013 at 23:05

Ok. Think i will. Thanks

Monkeyspaz5000 · 19 Jan 2013 at 23:06

Just make sure you have reasonable clearance underneath the case. Don't go putting it on a really thick pile carpet etc. Make sure the PSU can draw air in.

Michaeljcox24 · 19 Jan 2013 at 23:07

Its on a glass table. Should be ok apart from the corsair logo being upside down.
