The demonstration video for Novec's Iceotope features a full submerged and functioning iPhone, as well as a less expensive phone, neither of which suffered at all from being dunked in the non-conductive liquid; you should probably wipe them off before using them though. This project from Leeds University claims an 80-97% improvement in cooling efficiency over air cooling though they do not compare it to mineral oil or other exotic cooling solutions. Head over to The Register for a look at the demonstration video.
"We've seen quite a few innovative engineers who have tried to bring down data centre cooling costs, including this mad crowd who dunked theirs in a deep fryer... Now boffins at Leeds University and British start-up Icetope have invented a super cooling liquid that could create a new generation of "wet servers". They say it could cut the cooling costs of the world's server farms by 97 per cent."

Intel has been dunking servers in oil for the last year and found the practice to be both safe and effective. Ironically it has been almost a year since we played around with mineral oil cooling – and when we did – we did not want to upgrade or fix anything. Intel agrees.
Intel inside, slick mess outside.
Often cooling a computer with a radiant that is not air focuses on cooling a handful of specific components and leaving the rest exposed to air. Gigabyte in their recent live presentation showed how the company reduced waste heat on the motherboard as it delivers power to the CPU as the latter likely receives more cooling than the former. With mineral oil you are able to more efficiently cool the entire system by immersing it in a better coolant than air.
This still makes Ken wake up in a cold sweat… is what we convince ourselves.
After a full year of testing servers, Intel has decided that oil immersion cooling should be utilized by more server hosts to cut costs over traditional air conditioning. In their test they used heat sinks which were designed for air and dunked them pretty much unmodified into the mineral oil dielectric. Apart from the mess of it – Intel engineers always carried cleaning cloths just in case – Intel seems to only sing praise for results of their study.
Of course Intel could not help but promote their upcoming Phi platform which you may know as the ancestor of Larabee.
Now the real question is whether Intel just wanted to shamelessly plug themselves – or whether they are looking so closely at alternative cooling solutions as a result of their upcoming Phi platform. Will we eventually see heat dissipation concerns rear their heads with the new platform? Could Intel either be sitting on or throttling Phi because they are waiting for a new heat dissipation paradigm?
Could be interesting.

If you have an urge for switching your PC 's' cooling to full immersion in mineral oil you could do worse than looking to Puget Systems and their DIY Aquarium kit. For four years they have been perfecting one of the most unique PC designs on the market, mimicking the look of an aquarium right down to the overhead light and gravel at the bottom. By ordering a complete system, or picking up the parts from their parts store to build your own, you will end up with a well cooled conversation peice that you should proudly display in a prominent place. Plus it is still a working PC, even if you will be distracted from the screen by your case.
In House Manufacturing
We have seen so much demand for our aquarium kits that we have purchased our own laser cutting machine! This allows us to manufacture these kits entirely on our own, which carries a number of advantages.
- Our costs are lower, which helps lower the price to you.
- We are in full control of quality.
- We know what is needed much better that an outsourced machine shop.
- We can make MUCH more frequent design tweaks and improvements.
Up to this point, our aquarium kits have been getting bigger and more complicated with each release. The V4 kits take a step back. The size and capacity is the same as our V3 kits, but with the advantage of rapid prototyping though on-site manufacturing, we are able to create a much more finely tuned product. Instead of large bulky bracing, we cut it down to only what is necessary. Instead of dual pumps with complicated interconnects, we run a single more powerful pump. This leads to a dramatic decrease in complication, assembly, and number of parts needed. This results in less points of possible failure, and much lower overall unit price.
For those interested in the full history of this project, Puget Systems has chronicled our timeline over the last 4 years, sharing our thoughts, testing, benchmarks, and results.
Our full V4 aquarium kits, including tank, motherboard tray, pump, radiator, and all necessary wiring and tubing, are available for immediate purchase on our website. Alternately, for those looking for parts for their own DIY projects, each component of our V4 kit can be purchased separately on our parts store.
