[LeedsUni] 'Wet' computer server could cut internet waste

post #1 of 12
Thread Starter 
Quote:
A revolutionary liquid-cooled computer server that could slash the carbon footprint of the internet is being tested at the University of Leeds.

While most computers use air to cool their electronics, all of the components in the new server are completely immersed in liquid. The power-hungry fans of traditional computing are replaced by a silent next-generation liquid cooling process that relies on the natural convection of heat.

But the significance of the new Iceotope server lies less in the novelty of its design than in the bite it could take out of the huge electricity demands of the internet servers that form the fabric of our online lives.

I know the idea of using a fully submerged computer and some liquid cooling isn't new, but I believe the idea of using it top heat places is biggrin.gif

Good stuff, I had my 3939k clocked pretty high this winter, H100 kept my room nice and warm!

Great concept, nothing new but interesting application.

My only question is where can I buy some of that liquid for worry free "water" cooling.

I guess some people have never heard of fluorinert by 3m.

What's being demonstrated in the video is just a new version of fluorinert called novek.

nothing ground breaking.

How does the thermal conduction compare to water?

Nope, never heard of it, didn't find it on 3m's site either. Thanks.

Figured that much; nothing new about the cooling and recycling the waste heat either. thumb.gif

Nice one, remember those old Cray supercomputers which came with a cascade cooler for the fluorinet? Trippy looking, like some high class fountain for a hotel lobby. Also if memory serves me well there is a video around of some company showing an aquarium pc cooled by novak right?? CPU and GPU had some blocks with high aspect ratio struts (cylindrical i believe) akin to a waterblock but with more bulk to them... lemme google for the vid.



Found it. It was Zotac at CES 2102. It was cooled by novec,(Novak keep showing tennis vids, lol) also by 3M.

Would it be more effective to cool the CPU and GPU dye in direct contact with this? Design the CPU block that uses the CPU itself as part of the sealing?

Don't think so, heat dissipation is still a function of surface area (mainly, there's also fluid dynamics). Like that new waterblock which had direct water contact w the IHS (on a thread by Stren) it performed worse than most others IIRC, it was limited by the exposed surface area. Even when with the die itself exposed (a la Ivy Bridge) dissipation still happens between the waterblock's surface and the water.


-edit-

Damn, sorry Zealot, didn't read your post well - I'm multitasking Civ V and oc.net. But you do have a point, if the IHS were designed with this in mind it would certainly work. Of course then business gets in the way, unless this kind of cooling gets widely adopted there would be very limited and expensive runs. Even more than those Expensive Edition processors.

If water did not damage the die is it more effective to cool the dye directly with flowing water or what we do now with cooper blocks? Maybe the dye has to be specially made to increase it surface are having micro channels itself. Current water cooling if good for low noise but most cases with current Chips its not that big of advantage.
