First Water Project: The Mad Titan

Cheers! :)



I am trying to build the best I can, exactly as I want it - sometimes my impatience gets the better of me, but hopefully not to the detriment of the build!
Drilling the case was scary, and I actually did mess the first hole up(!) but thankfully you can't see it!

Still a bit to do, but hopefully I will have more pictures up soon!

I wish you the best of luck for your build! :)

Cheers mate :)

Trust me, making mistakes is part of the experience, I made so many with drilling and cutting on my project, I just try to hide them all well! :D. I've been working on mine for months, normally I'd bang it out over a weekend!

Subbed this, looking good

Sure, I was going to get four! :) Seriously though its a benchmark thing, plus i have never had a three way before! :D
We all know the deal with Nvidia and 3-4 way setups now and lets face it, even with two way SLI we are going to have to wait for the drivers to catch up to really make use of it in gaming.



Thanks man, the hard bit is the pipework - which is tough!! :)

I take it you're aware about the key you need to unlock in the gpu bios to unlock 3 or 4 way sli? (Nvidia will still claim not to support for than 2 way sli however, the board partners will on their non reference cards) Also the old 3 way and quad sli bridges for the 9xx series are supposed to work.

In general, each addition of 120mm gives you much better cooling than adding more thickness where you will only see a few degrees here and there realistically

Yup, agreed.

Thanks man, I have made a couple of boob's along the way, but nothing fatal, I definitely need to get better at petg bending, that is tough! I will likely be doing an upgrade in December so I will have another pop at it then!

Your build looks sweet by the way!

No enthusiast key needed anymore, nvidia ditched that idea, it seems that now there is little support at all - my plan is to have a dedicated physx card unless I'm benchmarking - with this in mind I have both the new HB bridge and the older 3 way bridge!

Thanks again dude :)

If you can train the PET sleeving enough, I think you should have each set of 6+8 pin bend behind each GPU below.

Have 3x nice small curve, just like your tidy 24 pin. The yellow is a bit too dominating if it runs that close to the side panel.

Like this? It does look tidier by far!

I am concerned about the cables laying on the GPU's though.. How much should I care?

Tidy! :D

Depends how much pressure they're putting on the cards. There's enough insulation between the wires' plastic sheath and the sleeving, it's just whether it's pushing the card down hard and straining either the PCI-E connector or the water bridge.

If it is an issue, have a search for "Hex Gear 180". I've seen some similar custom-built combs in aluminium by a forum member too.

I have a hex gear in purple and and another in black, although I don't really want to use them.. The branding just puts me off for some reason.. Plus, they will be upside down as the holes are not in the right place! :)

SCARY UPDATE!

Ok, so I have all my 2kw PSU cables plugged in, except for a few fans and the water pumps.

I am going to begin a new build in the next few weeks with my Caselabs BH4 that should be arriving in the next few weeks, so I already bought my Corsair SF600.

I figured it would be a good idea to use the diddy Corsair for my leak testing, and decided to test it with one of the PWM splitters to be sure it worked ok. Now, here is the scary bit.

The entire system turned on.

I mean, everything, motherboard, PSU everything that was plugged into the 2kw PSU turned on! The 2kw PSU has no power and is turned off at the back!

WTAF is happening?! Could this possible be power leak? Or am I feeding power back top the 2kw PSU from the Corsair?

Any ideas?

Cheers

What have you got plugged into what? Specifically of interest is the ATX motherboard connector - if you've got the live PSU plugged into the motherboard ATX, it will light some stuff up. The best way is not to plug the live ATX into the motherboard and either short out the correct pins on the ATX lead to turn the PSU on (cheap but prone to error) or preferably buy an ATX jumper to do it (same thing but without the paperclip ye-haw factor).
 
Nope, none of that is happening mate. While the PSU is plugged into the mobo it is not live at all - turned off with no power cord.

The only live connection is the SF600 to the pwm splitter and the PSU cable on that has the pins shorted as you suggest.

This is really odd.
 
Yeah, that's sounding odd.

So you've got your test PSU with the ATX cable shorted (to turn it on) and that's plugged into the PWM splitter only.

The 2kW PSU is disconnected from the mains and turned off but its ATX cable is plugged into the motherboard and presumably most other things except the PWM splitter.

What about the 4/8 pin EPS cable that also plugs into the motherboard?

It couldn't be just that the fan in your 2kW PSU has a motherboard fan header connection and that's plugged into the PWM splitter could it?

Worst case, start simplifying things. Take the test PSU and fire it up with nothing connected to it. Start plugging things in until you recreate the problem. At that point, you know what it is that caused it. If necessary, you can plug in the PWM splitter on its own and then plug fans into that one at a time.

Yep, you got it mate.

I figured out what is going on... Check this out...

The aquaero 6 XT is feeding power back to everything else plugged into it! PSU through the molex connector (and therefore back to mobo), PWM fans through the 4 PWM headers and the light box through the rgb header. Quite how or why this is happening is unclear; but I have isolated everything, in order and this is the definitive outcome. Odd.

The Aquaero is powered (or not at the moment) by a molex (and also partially through the USB) connected to the 2kW PSU. Your PWM hub is powered by a molex or SATA power from the test PSU and has a connection back to the Aquaero. I'd be a bit concerned that it's shoving enough juice the wrong way through the Aquaero to power up lots of other things to be honest. It might be worth powering the Aquaero from the test PSU without the PWM splitter and make sure it all works properly.

Yeah I thought that, so I did a few tests.
The Aquaero works fine when powered separately by either PSU. Equally the same behaviour exists when using the 2kw to power the splitter with everything else plugged into othe other PSU. Oddly though the gpus and water pumps don't power up as not enough power I would guess.

I also removed the molex and the fans and lightbox still got power from the PWM splitter through the aquaero - so it's def the aquaero. All seems to work though when plumbed in normally.

Weird. I would have thought that with the Aquaero-controlled voltage regulation, it wouldn't be possible to have power flow the wrong way through it....but what do I know!
I suppose it doesn't normally come up because you've normally only got one PSU and it's either connected or not - rather than bridging stuff it shouldn't.

Agreed! Ah well, at least I know now! :)
I will take a voltmeter to it at some point to see whats what...

I am so close to finishing now though... Plus I have sold my old rig :( so I am without a PC!.. Just the backplates and two y-splitters (for the drain ports) to arrive and then full system and leak testing (the reason I will actually use my lil SFX PSU!) - then, hopefully I am good to go! :)

Thanks mate
