Naturally Aspired PC WaterCooling Club

They'll sit stacked with the tubing linking them. The rads have inlets on front and back so I'll use a very small tube connection with stubby barbs. I'd draw a pic but I'm posting from my phone on work.
 
And they'll sit in the front 5.25" bays, right?
 
Yes. Where my single 120 is now.
 
New Dual Loop - 8 hours of puzzling!

Hey all,

So I took a day off work, took my deliveries and spent 8 solid hours (minus 45 mins with Mr Hawking's Universe for lunch).

I'm now running a dedicated gfx loop in parallel and a dedicated cpu loop with twin 120 rads in series. It's amazing what fits inside a TJ07 case. :D

EDIT: Tried some benchies. With fans at 600rpm my top temp on cpu (at 4GHz was 72 degrees after running Intel Burn test for 5 loops on Very High Stress). Ran Heaven 3.0 a good few times and the gfx cards were moving to low-mid 50's (again - 600 rpm fans). Played some BF3 (20-30 mins) after all the preceding and the cpu stayed way cooler, mid 50's-low 60's) but that was with adjusted fan profiles so the two 120's were running faster. All in all very happy - I now have a more technically organised loop and a quieter & cooler one despite running 2 overclocked 7970's and a i73930k (which I'll pop back up to 4.2GHz).

Anyway, hope you like the pics.

Dismantled most of the old loop. This was the easy bit.

This monstrosity cools the cpu. Twin 6cm XTX rads with 2 x Enermax PWM fans. 20cm thick.

GFX loop installed. Surprisingly easy to do. Using Alphacool Y-splitters and rotary 90 degree barbs. It took me forever to figure out where to put the pump and res for the cpu loop. In the end it seemed so obvious for the reservoir to be suspended where it is.

Now for the glam shots!!! (one wont load and it's my avatar pic - it's the prettiest!)

What are typical pump temps for a laing D5 vario@4 and a laing D4?

Capture009.jpg


Optional temp 2 is the D4, optional temp 1 is the D5, (temp 3 is the copper plate on the CPU block :p), just seems odd to me the temp difference between the two?



And does anyone have any experience with one of the XSPC dual Laing D5 bay res's? I am looking to clean the case up a smidgen and that would help.

To me it would make sense that a newer pump would run cooler.

What is odd about that is the D4 is older running full speed while the D5 is knocked down to 4 on the dial.
 
Bah,

My twin linked 120.1 rads aren't performing as i thought they would. My cpu temps are getting too high. In real life stress (BF3) the hottest core is hitting high 60's. When i ran Prime the hottest core hit 79 today and that was with a very minor overclock (3.8GHz).

The radiator housing is very warm to touch so i know the heat is being taken away from the cpu, it just seems to be that the cooling set up is inadequate. I think the first radiator is just venting hot air onto the second and the heat dumped onto it negates the convection of heat away.

The cores idle at about 26-37. When i start Prime the top temp rises to 56 degrees immediately (no issue there). But after ten minutes the top temp is at 70 and climbing. It leveled off yesterday at 74/75 degrees.

It looks like the loop is heating up and not dispersing enough heat. The stacked 120.1's don't work well it seems. Plus a low volume of coolant in the loop.

Think I'll get a 240 radiator and remove my optical drive. Shove the new rad vertically in the front bays. And get a bigger reservoir.
 
Yeah, thanks for the link Radrok. I've purchased a 240. Two 120 rads coming to the buy/sell forums soon, lol.

EDIT: Quick drain and some jiggling about. Removed the sandwich fan and temps about 5 degrees better now. Will still install the 240 rad though, should cool it better with no heat dumping onto the cooling set up.

Who'd a thunk it? Sandwiches may work on air coolers but on rads they make it worse!

Have a look at this

Stacked radiators perform terribly compared to separated and even to a single.
Are those fans carved with Enermax logo?
If that is so they may probably lose static pressure due to an alternative air escape path ( I am just guessing though )I may be wrong about them.

The issue with radiator stacking is people do not keep a high enough static pressure across them. With radiator stacking like use while using 38mm 255CFM fans temps were lower with the stacked rads vs without. It would be no different than managing to use 6 fans on a double thick radiator.
 
My problem is I use low rpm fans with low air movement (my PC is very quiet). I can get them higher but in this instance as well the sandwiched fan was of lower rpm (whoops). Didn't realise it until i got it set up...

Played 1/2 hour of BF3 there and temps stayed 55-65 (@3.8GHz). Happier now but will enjoy tinkering again next week to finally finish my PC.

Mine are knocked down to 5v so they move air, but not the 255CFM they are rated for :laugh:
 
I guess at 255CFM the damn thing would hover across your room :laugh:

The side panel flexes inward...That's 10 255CFM exhaust fans all in the top of the case...

I know about that but which fool would run 255 CFM fans at full throttle?

Really, if you are watercooling and your rig is noisy then you are missing a big part of it.

I'd rather use more radiator surface than faster fans, anything over the GT 1850rpm is noisy for me.
 
Tore down my case to redo the cables...

Yes, but those fans at 15.5V (~8A for the pair) are able to do things like this @1.63v

Using a humble H70. Now when my ears stop ringing I will try a couple more benchmarks :laugh:
 
Looking at building a quiet big HTPC with the HAF XB.

Parts list in planning

Capture050.jpg


I already have the two lower rads (120x2 and 120x1) just listing them for posterity. Loops will be cooling the CPU and possibly dual GPU's.
 
this case?
