Beautiful, and your high power cooling device is a great technical solution.
Keep 2x690 cool is not an easy task.
BTW You use a single or double PSU?

Sorry my mistake, too many beers. I know it´s a 4x690 "baby monster cruncher".

Single.

There is a sense of charm to that picture, I really like it!

I usually don't leave hard drives on the floor but I had to change power supplies in the wee hours of the morning. I was using two four pin molex to eight pin PCIe for one card, manufactures way not to overload one rail. The supplied adapters were not a tight enough fit and partially melted; I should have checked out why the power warnings sooner.

Ok, here's my 2 rigs.
All business, the way it should be. Dancing red water cooling not needed. Boutique builders are not going to like what real world, get it done, machines look like.

Yup............
All business. Nothing pretty here. But we get 'er done.


BTW...
I do not EVER recommend tapping off the molex chain to power a GPU.
I learned this the hard way when one of my rigs melted down. The slight voltage drop across the molex adapters caused more current to flow through the main mobo connector and it failed. Melted down and took the mobo with it.
If you don't have the proper connectors on the PSU, don't do it. That's the reason I have one rig left that is running 460s instead of 580s.
I may at some point swap in a new PSU and upgrade it, but it's stable the way it is, and I don't wish to mess with it right now.

Hey Mark - do your kitties try to climb inside your rigs? How do you keep them out of there? Looks nice and warm to me...

Surprisingly, it's never been an issue.

They wander by and sniff at the noise the fans make once in a while, but never do mess with the rigs at all.
I think they are more than happy cuddling up on the nice warm waterbed and that keeps them out of mischief.

What is that on your CPU, a smoke stack?

That would be the pipe to the compressor above, which keeps the CPU chugging along at minus 30 something or so below zero.

More pics?
It is a very unusual rig.

Back in the day, cooling a CPU to unusually low temperatures had decided benefits.
You could OC until the cows came home.

Here are a few more pics....
You have to prepare the processor.

You have to prepare the processor. Freezing a CPU to subzero requires that you block out moisture.


This is the compressor. It takes a special mix of certain freons to achieve the maximum cooling whilst at the same time minimize chugging should the CPU stall at it's chores. It took 3 months with some guy out east for days on end to come up with the freon mix.

So, that's where the stack goes.
-30c or so.

Meowbrrrrrrrrrrrrrr.

Yes, there are various mixes of freon coolants.
r this, r that, \
When in a closed system, they all respond differently.

Some choke up at certain low temps.
Some just make the compressor lock up.
Which kills the compressor.
Some 'slug' at low temps, which means that the refrigerant returns to the compressor as a fluid rather that a gas. Which destroys the compressor's valves.
I went through several months of experimentation and burnt up 3 compressors before the dude and I finally came up with a mix that worked.

It is still working now.

It's the only rig that requires a manual restart, as the mobo and the chilling system have to be in synch somewhat.

The CPU will not reboot unless it's happy about sub zero, and the compressor gets a little pissy about not having a load to cool. Funny shit.

It's my rig 5082339.
And it's not really that amazing other than it is running at 4.189Ghz, which ain't bad for a processor of it's vintage. 2 680s on board.
The Fluke 51 thermometer right now says........... -27 celcius.

Today's processors can be taken to such speeds on air cooling.
But, back in the day, that rig would cool a Sempron toaster down enough to run at unheard of speeds for the time.

I am waiting any day now for the compressor to go kaputsky.
It's been running 24/7 under heavy load for years now.
If and when it finally fails, I'll have to retool the rig. Probably go for some kind of self contained water cooling setup.
Cooling is just not as important as it used to be now that processors have become more energy efficient and don't dissipate the power levels that they used to.

Maybe I can come up with some kind of water based system that makes pretty bubbles or something....LOL.
