My New Winter Project

Jokester · 13 Nov 2011 at 22:27

My other case is fully passive

They're HWL SR1s.

Had a major reroute today as I found the res was clashing with the GPU, looks tidier though.

Jokester · 14 Nov 2011 at 20:41

Going to take forever to fill :/

Edit: Going to run out of water at this rate!

Jokester · 15 Nov 2011 at 18:06

Got one big leak,going to run it for few hours though to see if there is anymore drips.

ot so sure on the case bottom rad pluming or a single D5. I have the 560 SR1 and it does take a lot to move water around!

All three rads are in parallel so the restriction will be greatly reduced. A single D5 will handle it no problem.

Had a compression fitting fail, couldn't have made it up right. So when I get home tonight I'll buy some more water and retune that one bit.

How much length does the suspended d5 add? I assume that's your mod for completely isolating the noise!!!

You don't need much at all, that's enough there to stop any vibration being transmitted any further and the pump itself is next to silent.

Lesson learned, the EK mounting kit for their res' is useless.

PSU extender, with dual Seasonic 450W passive PSUs.

And connected up.

Now running Prime to see how different temperatures are compared to my passive set up. Currently looking like 15C better temps.

EK make useless res holders whitch don't tighten at all

If the motherboard wasn't there, it could look like a house missing some walls with all that plumbing.

Tell me about it, the screws are too small for the hole :confused:

Haven't been able to hook up the Tbalancer yet as I don't have the right USB cable to fit it, once I've done that I'll then be able to check flowrates and so on.

Cleeecooo said:
What's a tbalancer?

It's a programmable fan controller, I'm going to connect all the fans to it, the temperature sensors and the flow meter amp and I'll configure it so that when there's no load it'll be quiet and if the water heats up to much it'll ramp the fan speed up.

Cleeecooo said:
What's the point?
You have 3 480mm SR1's - the water will probably be in the negatives!!!

12 fans at full speed is pretty noisy!

Jokester · 19 Nov 2011 at 18:22

It's 8/11mm tubing.

What I'm aiming for is to have the fans running at 200-300rpm when idle (might even switch most of them off if possible). Then when at full load have the fans all ramp up to 100%.

It has to be asked... why the hell would you want that?!

Why not just keep it quiet throughout?

Because more cooling = more overclock :cool:

Cleeecooo said:
What is it that you're cooling again?

Surely with so many rads, you can OC to the max anyway unless of course you have 2 i7's and 4 590s with a 480 for physx!!

At the moment it's a 2600K and a 580GTX, but I'll be going IB + CF/SLI next year.

Jokester · 19 Nov 2011 at 20:08

Cleeecooo said:
that definitely can run passively on so many rads!!!

Nah, was hitting 80C, it'll happily run passive though at idle though.

Jokester · 19 Nov 2011 at 20:17

Currently running 2.4lpm through the CPU block, 0.9lpm through the top rad, and 1.2lpm through the bottom two. Slight in accuracy it seems as the total of the two rad flows should equal the CPU flow.

Edit:
CPU flow rate with 3 rads online is 2.45lpm
CPU flow rate with 2 rads online is 2.25lpm
CPU flow rate with 1 rad online is 2.15lpm

Jokester · 19 Nov 2011 at 20:49

Cleeecooo said:
Does it matter if it's different?

Well, either I've got a 300ml/min leak, or the flowmeters aren't totally accurate.

Reckon the meters would be accurate to 5% which is actually quite good.

Jokester · 19 Nov 2011 at 20:57

Cleeecooo said:
How did you work that out?!

I never thought one person could hold so much knowledge!

The CPU flowrate splits in two, part of the flow goes through the top rad and the rest goes through the bottom two. The flowrate through the bottom two should be more or less double the top one as they will be half as restrictive. It's only different because of the inaccuracies of the flowmeters.

The amp actually has a switch betweem 6mm ID tubing and 10mm tubing. I'm using 8mm tubing so it'll be somewhere between the two in reality, so I've went with 6mm tubing which gives a slightly lower flowrate measurement.

Would it not been easyer to build a chea MDF frame for the WC, pump, ball vlaves etc and have it all layed out flat to test. Be cheaper and easyer to work with!

80c!! My 17 2700K @ 5GHZ cooled by EK Supreme HF new plate, DIYINK 12W DDC, EK DDC top/res & SR-1 560 doesn't get that hot as a pasive item!

That's 80C when Priming though!

Jokester · 20 Nov 2011 at 12:55

Started doing some load testing today, running OCCT 4.0 for 1hour.
Peak temps:-
3rads - 57C
2rads - 59C
1rad - 62C

So going from 1 radiator upto 3 in parallel only drops peak temperatures 5C!

Jokester · 21 Nov 2011 at 12:12

Series is considered worse, because not only are you losing the maximum deltaT, but the increased restriction cuts flow rates. Even just valving off my radiators was dropping the flow rate. Adding them in series would have reduced the flow even more.

The only downside to parallel is that the individual flow rates in each rad is less than in the common section, but rads are much less flow dependent compared to CPU blocks.
