Submerge your rigs in liquid

What's the point, if you're still gonna use NINE(!) 12cm case fans? Why not just watercool, as  any noise advantage is not thrown right out the window.

What's the point, if you're still gonna use NINE(!) 12cm case fans? Why not just watercool, as  any noise advantage is not thrown right out the window.

Perhaps this might be the point, at least from a data center's perspective:

And the technology is incredibly effective. Patterson said that whereas traditional air-cooled server racks often operate at a Power Usage Effectiveness rating of about 1.6 (meaning cooling tacks on a 60 percent increase over the power needed power the servers' computing workloads), Intel's oil-immersed servers were operating at a PUE between 1.02 and 1.03. It's possible to achieve similarly low PUE ratings with traditional air- and liquid-cooling methods, Patterson said, but getting there can require some serious engineering effort and cost a lot of money.

really cool but i agree about things getting messy

Novec 7000

That's very cool stuff.

+1. That's a clever concept, keeping the fluid circulating without a fan or pumps.

I've been messing with the idea of making a cooling setup that uses Novec 7000 for my SC Singles (Gallery here).

It's still a work in progress.  I'd shelved it after I'd heard that the new ASICs should be much more heat-tolerant, but recently there have been talks that they can be overclocked, so I am thinking about putting it together again.

that stuff is really expensive.....

that stuff is really expensive.....  

I only found 1 posting online from 2 years ago saying $350/gallon
Maybe the price has changed a bit, but this would still be awesome to have for someone who has dozens of rigs going.
They would obviously be able to afford it, and the energy savings alone would be great.

Yeah, it's definitely a high-ticket item, but my concerns when I was coming up with this were:

Power Consumption - I pay on average $0.36 per kwh, so with the cost of running both the singles and keeping them cool, is ridiculous.

Corrosion/Humidity - I live near the ocean, so I worry about the lifespan of the devices with all the humidity and salt in the air.

How cool it looks - If it's going on my desk, I don't want a bird nest of wires, components and junk.  I want it to look good.

Doesn't seem worth the expensive.. now.. oil cooled asics... hrm might be an idea!

When I was running all five of my singles here, the electrical costs were more than $400 a month.  If it cost $1,000 for a passive cooling setup, which would drop that to $200 or less a month, it'd pay for itself within five months.  Looking good while it did that would be a bonus.

Awesome, thanks for posting some monthly electric costs.

I've recently got my HTPC and FPGA Mining Rig stable enough I don't feel the need to constantly tweak it and went ahead and did exactly what I had always planned for it. Oil Submerged it in a thin framed glass fish tank, it looks beautiful. Still tweaking, but once it's finished I'll remember to take pictures to show it off.

Novec 7000

Very impressive !  Thanks for sharing..

As for HDD now turning to SSD, I think the future is no moving/mechanical part at all... very interesting tech !

Imagine what tech will be availlable in the future

It still gets hot... Think of it like a deep fryer,

Yet, another use for GPU's, Turkey fryer.

You can also fry your hands with 'gaming' laptops

How about the mineral oil itself and the Novec 7000? Can those fluids be recycled? That's a major factor before adopting IMO.

More than clever. It's not simple immersion cooling, it's evaporative cooling: any component reaching the boiling point of the liquid (34C in this case) will cause the liquid to boil. Heat of evaporation takes away all the heat from that point on, it's almost impossible to go above 34 C in this case. Most of vapor is then condensed at the heat exchanger, and recycled into the system. This heat exchanger is likely the most problematic part: it's got to be able to dissipate heat into the surroundings at the rate sufficient to keep the hot side below boiling point of the liquid.

Good luck trying to use it in warm climate like where i live, +36ºC all year long. it would be interesting to see a Pressure-Temperature diagram of the stuff.
