Hi. Here is the build I want to do. It'll be my first water cooling build. In fact, it'll only be my second rig I've built.

Here is a picture of what I propose to do.

The case is Caselabs STH10. I can't afford to fill it up to the max at the moment, but I really like the future potential of the case, and I WILL be using all its space (when I can afford it!).

Sorry for the **** picture. I hope it's clear enough. I've tried to include the fittings I will be using, but it's rather hard to work it all out without the stuff in front of me.

Anyway, I'm just interested in what you chaps think/any recommendations you would make? Remember, I am a noob at this, so it may be that the parts I have chosen are not right. I have spent a long time reading up about water colling and reviews on products, but like I say, I am new to it. So with that in mind...

As you can see, I'm planning on using mostly 90 degree rotary fittings. It's going to be expensive, but it seems the cleanest, most fool proof way of doing things.

I have at this point NO idea about how/where to drain the system, so that needs to be worked out. Not sure how.

I'll be using x8 gentle typhoons on the rads (one sucking in cooler air, the other pushing the heated air out). Push pull is a bit beyond my wallet at the moment.

If you can think of a better way of routing the tubing, I am all ears!

Thanks for any input

PS I've been told I should go to CPU first rather than GPUS since I'll get a better high flow rate. So now I probably have to change it all around :(
 
It shouldn't make much if any difference what order you go into the blocks, just do it the cleanest way, which would appear GPU>GPU>CPU in your case.

You should/could also go direct to the CPU from the pump (couple of 45 deg fittings) then down to GPU's and then to radiator and loop back up to the res?
 
Yes, I was thinking that. Thanks. Could work. Is it OK to do what I plan in terms of hose to radiators? It's a long stretch of tubing with a 90 degree bend. That OK?
 
BTW I hear it said - just go for the cleanest look - and that's great. But I have also heard that highest pressure should be going onto the CPU, in which case I need that to go first.
 
No in terms of the tubing arrangement, split the flow in two between the radiators rather than putting them in series. It'll improve your flow rates elsewhere in your loop by reducing the restriction.
 
What components is this cooling? 2 480 GTX rads seems overkill for nearly all systems! If youre going for silence then GTX rads aren't for you... you'd be better off with 2 Black Ice SR1 480 rads which are designed for slower fans. Would still be enough probably, depending on your setup, which would allow you to use quieter fans...

Or just use only 1 rad...


Only way I'd consider that wc setup is if i was using triple gpu and the latest CPUs

EDIT: Just saw the 2 GPUs... I still think it is overkill though... what do others think?
 
To get the best temps you'd be better off complicating the loop by going:

Res
Pump
Rad
CPU
Rad
Gpu1
Gpu2
back to Res

Your rads will remove pretty much all of the heat that is in your rig by the time the fluid has passed through them, most of the heat removal will have happened after passing through just ONE of them. The temp delta will be negligible over the second rad.

If you aly them out as I suggest, then any heating done by the CPU will be removed by the rad, then the GPU's will receive COLDER fluid to cool them, resulting in lower GPU temps.

If I make a rough guess at the temp throughout the loops:


Res - 44
Pump -45
Rad - 30
CPU - 70
Rad -30
Gpu1 - 42
Gpu2 - 45
back to Res

Using your layout I'd guess the temps would be

Pump - 30
res - 30
Cpu - 70
Gpu1 -55
GPu2 - 60
Rad1 - 30
Rad2 - 29
Back to pump -30

The temps may or may not be accurate, but they reflect what is happened. How do I know? I went from a loop like yours to 2 loops and this is exactly what I saw.

Now mine is

res
Pump
phobya 360 rad
CPU
Swiftech 120 rad
and back to Res

and
Res
Pump
Swiftech 2.120 Rad
GPU1 (GTX 480)
GPU2 (GTX 480)
Swiftech 2.120 Rad
and back to Res

Get a colder feed into you GPU's.

Admittedly my GPU's not a Socket 2011, but it is an i7 950 @ 4.2Ghz on 1.45v 24/7 folding.

My heat exchange must be quite efficient because I've not had the heating on in my room now for 3 years. I sometimes leave my door open to warm the rest of the house... ;)
