Oil-Immersion Cooled PC Goes To Retail 210
notthatwillsmith writes "Everyone's seen mods where someone super-cools a PC by submersing it in a non-conductive oil. It's a neat idea, but most components aren't designed to withstand a hot oil bath; after prolonged exposure materials break down and components begin to fail. Maximum PC has an exclusive hands-on, first look at the new Hardcore Computer Reactor, the first oil-cooled PC available for sale. Hardcore engineered the Reactor to withstand the oil, using space-age materials and proprietary oil. The Reactor's custom-manufactured motherboard, videocards, memory, and SSD drives are submersed in the oil, while the dry components sit outside the bulletproof tank. The motherboard lifts out of the oil bath on rails, giving you relatively easy access to components, and the overall design is simply jaw-dropping. Of course, we'd expect nothing less for a machine with a base price of $4000 that goes all the way up to $11k for a fully maxed out config."

Patent for Liquid Submersion? (Score:5, Informative)
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?

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).

Here's their patent claim (Score:5, Informative)
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:
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 [3m.com], 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.

It's also oozing with potential patent abuse:
U.S. Patent No. 7,403,392 [patentstorm.us]: A portable, self-contained liquid submersion cooling system that is suitable for cooling a number of electronic devices, including cooling heat-generating components in computer systems and other systems that use electronic, heat-generating components.
How delightfully generic and self evident. Nobody has ever thought to immerse components in liquid to cool them.
Fallacy: oil based PCs don't break down over time (Score:5, Informative)
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."

So, I actually interviewed here prior to the product launch, and got to see this (under NDA, of course). The motherboard is SUPER proprietary, a joint venture between Hardcore Computer and Tyan (which makes pretty decent equipment, IMHO). Of course, it does still take standard CPUs/RAM. But just in case there are any doubters out there, I've been to the facility, seen the board-level techs they have on staff, and played with, first-hand, one of these suckers. They've put incredible R&D into this (took them a couple of years to finally get to launch). I'm not an employee, just someone who's seen these and was pretty impressed. Also feeling vindicated, since I knew from the second I saw it that this would end up on Slashdot :-)

They also use SSD's because they aren't mechanical and can be immersed, allowing you to actually cool your hard drives, which is sort of the point.
I'm not sure whether the time is right for this technology, or even whether it's a particularly good idea, but there's a good reason for the SSD's.

Regarding fire hazards: This is no problem, oil has been used for ages in heavy power switching equipment to quench the electric arc which is made when switching. See http://en.wikipedia.org/wiki/Switchgear [wikipedia.org] for a reference.
As far as the rest of your points - agreed :-) I don't see the added value too, except for bragging rights.
