By removing fans, lowering working temperatures your are lowering resitance which converts into lower power usage.
With recovered, sometimes MW of power You have heat source capable of heating towns.

Cryptominers should not exist in the first place, they should be illegal to produce and operate. The amount of energy they consume doing useless busy work is obscene and has completely negated all the progress we have made toward greater efficiency and lower environmental impact.

Rebonjour Cher Pavel, j'ai connexions forte à Pologne.  BRAVO pour votre efforts et idées nouvelles.


I was electrical engineer since ,1968, consultant and manufacturing spécialiste in high voltage, power supplies, magnetics, up to 12 kW and 75 kV. Now long retired!

Best référence book on utility transmission and distribution transformers, most oil cooled, since,1925(!) is classic, The J&P Transformer book éd Martin Heathcote.UK,
costly but earlier éditions are fine, my tenth ,Ed,in London, Foyles in 1973....was,£25!

https://www.amazon.com/J-Transformer-Book-Martin-Heathcote/dp/0750681640/

Je suis très heureux pour un vidéo ou appel via Skype, Facetime, Zoom.

PM me with contact information.

Amicalement

Jon

Make the busy work not useless, as Curecoin and Foldingcoin do. Or make it something that uses less energy, but that's a harder problem to solve in the long term.

If it uses less power it's not going to be worth as much. If you try to make something that consumes little power, someone will just use bigger hardware that uses more power in order to mine it faster. I don't see any way to make it hard to mine that won't also encourage large amounts of power to be used. The entire concept is fundamentally flawed, and all crypto is useless as currency because it is so unstable. If you can make a lot of money investing in it then it's not a good currency.

While it certainly can have some niche applications, and I don't doubt you have a great product here, my point was that it made absolutely no sense to cool down a desktop PC, which was the point of the thread.

Even for servers, that's something that would be used with a lot of thought. Not just submerging the whole hardware in mineral oil. The resulting weight would be enormous (causing specific issues for mounting purposes) and, it would render any maintenance a horrific process.

I completely agree. Immersion Cooling is not for desktop PC cooling (although You can do it - history of this post shows that.

Our installations are achieving PUE at < 1.04 One of the best DCs in my region (air cooled) are proud to get lowest PUE at around 1.2
Think about OPEX and savings on cooling (which is one of the biggest parts of OPEX costs for DC).

You are removing noise and vibrations - completely. Virtually, there is no noise ;)


Maintenance: That is correct. It's not horrific process BUT requires different approach. I do totally agree in that point. On the other hand keep in mind all the advantages of the instalaltions: lower power usage, no noise, no dust, better cooling and what is MOST important for me - EASE OF HEAT REUSING

Lower temperatures is also a field for overclocking if needed or lowering power usage even more - with lower temperature comes lower power useage at same CPU frequency . Paper towels shouldn't stop You from choosing right direction.

Once again, I would like to point out that we are not using mineral oils. We have fully synthetic immersion cooling liquid [physico-chemical properties are on our web page]

Weight Yes - that is a thing to consider. Especially when with immersion cooling You can achievie MUCH HIGHER hardware density per square meter. But hey, we are engineers - everything can be calculated and designed.
