Getting ready for test runs with a X2 4600+ "ES" on air...Monster LS is INBOUND! 7800GTX cards were running 594 core BEFORE watercooling (on air only)....get ready for some BIG clocks....

More to come...

This is a MCP655/D5 you are using? The D5 shouldn't mounted upside down according to Laing manual. Let us know how long it survives.

Otherwise nice installation.

might want to move the pump so its not facing down (thats the worst way to have it) and also move the T-Line to the last thing in the loop.

freecableguy

11-11-2005, 09:12 PM

Max...i have to disagree about the pumps, that's the best way to have them

as for the t-line...where does it matter where it is....it doesn't, just as long as it's in a good spot, and it is...

MaxxxRacer

11-11-2005, 09:29 PM

your absolutely wrong about the pump FCG.. talk to BillA, laing engineers or even Iwaki engineers and they will all tell you NOT to do that.

having the T-line where it is depressurizes the water and thus will reduce the flow rate. not dramatically, but it will. Not going to go into an explanation right now but trust me it will.

afireinside

11-11-2005, 09:32 PM

That looks sick FCG! Can't wait to see the monster LS on there :slobber:

How the hell did you fill the loop though? It takes me all day to fill a t-line setup with the t-line right at the pump, yours is on the other side of the case and the pump is upside down...

Shader/ROP domains are now up to 621 with no problems...I will be going higher soon. I need to tweak the cores and the get the ram sinks on the cards, then I can get the GDDR3 back up to speed...

The inlet of the pump facing down as you have it is indeed the worst possible pump orientation there is. I don't mind where the tee line is however.

freecableguy

11-12-2005, 12:06 PM

I see many 300HP centrifugal pumps (almost on a daily basis) with the inlet facing downward and the discharge on the side. As long as minimum NPSH is being provided and the pump is not cavitating there is no problem. I don't know where this "don't face the inlet downward" theory came from but its not right.

nikhsub1

11-12-2005, 12:11 PM

FCG, it is listed in the Iwaki instructions, "Avoid a head down orientation". This is simple physics man. You want to flood the inlet. The pump will probably be OK, but that does not change the fact that it is not optimal in that position.

freecableguy

11-12-2005, 12:20 PM

nikhsub1 - if you want to jump and MSN and chat with me about this, OK, but I'm not going to argue with you about the position of the pump. Like I said, minimum NPSH is your only concern...static pressure on the eye of the impeller of the pump. As long as it is not cavitating IT DOESN'T MATTER.

Notten

11-12-2005, 12:29 PM

This is simple physics man. You want to flood the inlet.

How can that matter in a closed system? There is always water in the pump/pump inlet? :confused:

How can that matter in a closed system? There is always water in the pump/pump inlet? :confused:
It certainly matters a lot less in a closed loop system. However, if there is any sort of minor leak, or evaporation from that particular loop, the first thing that will suffer is the pump. It will start sucking air.

The only thing i know for sure is that the Laing manual for the D4/D5 expressly show upside down installation like this http://www.honigtopf.mynetcologne.de/einbaulagen.jpg

Now i can only assume that this way of mounting will result in air getting trapped underneath the Rotor and thus causing vibrations, especially at start-up .

The Laing design is very wear resistant, but I would think that the lifespan of the rotor is drastically reduced by upside down installation. Please tell us in case it breaks in a few weeks/months so future generations can see the value of rtfm.

Question: Shouldn't the first discharge out the pump go straight to the RAD

then to the first GPU then second GPU, inlet pump, T-line to RAD again?

damn.. thats a really good place for the pump.. it never ever occured to me to put it someplace like that.. if i ever decide to WC my GPU (and i believe i will soon) then i'll probably have to re-mount my pump and that looks like a good spot

Nice looking rig, I like the loop except for the pump orientation also, but it's your rig, so whatever. It makes me want to build a mid tower box out of pa160's now just for the hell of it. Add some color in that loop :)

freecableguy

11-14-2005, 03:31 AM

mid-tower box using a PA160 because it is going on top of a BB mods's/chilly1 unit that is fitted to a vapo LS unit. I needed the cases to match up.

FCG-

Xtremely nice setup there, very clean and well thought out.

Did you ever get your DK8EW set up?

I got my DK8EW from da'egg Friday and all my w/c stuff came in from the UK on Saturday. Now to hack-up a perfectly good LianLi PC-76 and stuff in 2 PA120.2s, 2 AquaXtreme™ 50Z-DC12's, 2 Storms, and 2 Maze4 gpus. I have 2 246HE optys, but no vid cards or ram yet.

I know you get some of the best equipment out there, so what are you going to use for ram in your DK8EW?

Best of luck on whatever you stick underneath that modded LS!!

i believe the reason liang says not to mount the pump like that is because it may lessen the amount of water that can get behind the impeller to lubricate the bearing.

Shouldnt matter really, the pressure in the loop wil probably force water back there. Looks nice.

snowwie

11-15-2005, 01:55 PM

it's not really a big deal with the inlet upside down...just as long as the impellor housing is flooded really. however it can be an issue when the pump is as high in the loop as it is in the picture...the water level in the t-line looks like it is lower than the pump impellor...but if there aren't any bubbles bursting forth or gurgling noises from the outlet when you turn on the pump then i guess it is flooded and it's fine.

for the record, though, laing pumps operate fine in ANY orientation (including face down), has been stated by billa. swiftech sells a res/DDC combo and you can see clearly that it is designed with the pump facing down at the ground.

BING! We have a winner...as long as there is no air in the system to collect at the impeller and the pump is not cavitating (easily verified by listening/feeling/visual observing the pump operation) then there is no problem with this orientation. I have adequate level in the t-line form a sufficient water seal.

Please let me know how that PA160 rad works out as I just modded a stacker case yesterday to except that very same rad and will be building almost the same setup using a storm and maze four.

*self-contained in a Lian-Li PC-60B case
*autocascade retrofitted into a stock VapoLS case
*EXTREMELY quiet with all low-speed efficient fans an a super quiet NF9 compressor
*near -30C idle and -15C load with 1.65v and 3.6Ghz+ FX-57
*dual BFG 7800GTX 512MB cards at 700Mhz core, 31C idle/38C FULL load

Thanks

Evap idle: ~ -53 to -55C
Full Load: ~ -40C

Unit will be going back to chilly this week for a revision refresh to include evac, rebuild, new insulation, lager condensor and next revision heatexchanger and finally a new tuned regas for a FX-57 @ 1.65v. Hoping to get temps 5-10C colder.

Good lord FCG. You own the ultimate 24/7 rig. :slobber:

FX57 @ over 3600MHz - Is this your 0512? Amazing...

Dual 512Mb GTX's @ 700mhz core 38c load, dual maze 4's and the PA160 right?

What fans could Chilly have put in that cascade in that tiny space to keep load temps that low and noise as low as you claim? I'm really curious.

Amazing rig FCG, congrats on it. :toast:
