Oil-Immersion Cooled PC Goes To Retail

Did you even glance at the summary before you started typing?

Patent for Liquid Submersion?

[RobertB-DC]

From TFA: "The U.S. Patent Office does indeed show Klum, CTO Chad Attlesey and CEO Al Berning with a patent for liquid submersion."

You gotta be kidding me. I've seen "PC in a tank of oil" on Slashdot half a dozen times. Or is it not a real technology company if they don't have at least one bogus patent on an obvious process?

rushes off to patent "Method for legitimizing a company and attracting venture capital by means of a transparently invalid patent application"

The storage provided by the manufacturer is SSD (three of them, in RAID) and is submerged, but they have bays for removable drives you might want to add on your own. Also, in response to your comment about resetting the CMOS, they have a button that does that on the case (behind a little plastic door so you don't accidentally hit it).

They probably mean bullet resistant aka Lexan.

Here's their patent claim

[Animats]

Here's the main claim from the patent:
7,414,845 Attlesey, et al. August 19, 2008
Circuit board assembly for a liquid submersion cooled electronic device

1. A liquid submersion cooled computer, comprising:

• a case having a liquid-tight interior space;
• a lid removably connected to the case for closing a top of the interior space,
• the lid including at least one pass-through connector;
• a motherboard disposed in the interior space and attached to the lid,
• the motherboard having a top end with electrical contacts engaged with the pass-through connector that permits inputs/outputs and/or power to be passed to the motherboard;
• a plurality of components mounted on the motherboard, including one or more of a plurality of processors,
• a plurality of memory cards,
• a plurality of graphics cards, and a plurality of power supplies;
• a dielectric cooling liquid within the interior space and submerging at least one of the components on the motherboard so as to be in direct contact therewith;
• and an impingement cooling system that includes a plurality of tubes for directing a flow of the dielectric cooling liquid directly onto two or more of the plurality of components.

The only novelty here seems to be in putting the connectors in the removable lid.

Incidentally, the cooling liquid isn't an "oil" at all. It's one of 3M's Novec engineered fluids, probably HFE-7500, which is 3-ethoxy-1,1,1,2,3,4,4,5,5,6,6,6-dodecafluoro-2-trifluoromethyl-hexane. It's usable for cooling up to 150C, nonflammable, does not irritate skin, does not contribute to global warming, ozone depletion, or smog, and the MSDS even says "Ingestion: no health effects are expected". 3M developed it as a replacement for PCBs and perfluorocarbons like Fluorinert. So it can be used safely by the idiots who overclock.

Fallacy: oil based PCs don't break down over time

[NotInfinitumLabs]

It was thought that the mineral oil on these PCs would eat at the Rubber seals or the contacts on the motherboard and cause the PC to fail over time. This isn't true. Here's a link to the year-after report on a oil-based PC that Puget Systems built: http://www.pugetsystems.com/submerged.php#update3

The most important part:
"# There is no sign of weakening of rubber seals or PCB. We have found that prolonged exposure to mineral oil does not eat away at any components. However, you will notice in the pictures that the voltage module for the LED light has fallen down. That module was stuck in place with nothing more than a sticker -- it took 9 months for it to come down! We're amazed it stayed up that long, but definitely recommend you do not rely on stickers or tape to fasten anything. Zip ties will be more solid and long lasting."

Re:And..... why?

The Buick thing is easy - it tells you what size engine is inside. The V6's have three holes on each side, and the V8's have four. And yellow and blue make green, so you can see when it is sealed. I thought that was well covered by the "yellow and blue make green" ad campaign.
