Unless X48 is the 7th (or 8th, or 9th; I don't remember what's the last one) Wonder of the World, 965 will be my alltime and forever prefered chipset.

Polywhat capacitors? I have no idea what you're talking about!

-70. You nuts.

Polymer capacitors.

----------

Here's the deal with supercooling :

From a 'materials compatibility' standpoint , there are 3 things on a motherboard that have issues below 0c.

1) The Battery.It has liquid/gel that will freeze and stop working.This is no problem , battery can be made external.

2)The Crystal oscillators that provide the 'clock' for fsb etc.Now , they still work cold , they just oscillate slower , so compensation is a must.

3)The electrolytic capacitors that are used in the power circuits.These also contain 'gels' that freeze.

Polymer capacitors don't use gels , so are immune to cold problems (theoretically)

---------------

-70 ain't crazy.I just wanna do some real overclocking.

The lowest temp for dry ice is -78.5c........I probably won't get that low , but the silicon can take it.

There are many examples of liquid nitrogen/liquid argon cooling for computers/processors.That's the true 'cryogenic' realm........-120 c and lower......

So you're talking about the "solid" caps, right? I know those were mostly introduced on the P35 chipsets, unless some very high-end P965 boards had them. But I'm not aware of that.

Yep , 'solid' caps are exactly what I mean.

They use a special plastic , rather than an electrolytic gel.

-------------

Quicky update on the design progress :

I have decided the original thinktank 'tank' wont do what I want it to......It'll probably explode and I don't want that.

I am moving towards building a 2 tank system (resevoir and active chamber) capable of circulating liquid nitrogen.....now I may not ever actually use LN2 , however I want it capable of that.
The first goal is to get a stable rig running as close to -78 as possible.Heck I'd settle for -60 at this point.

If I get that far , the next phase will be to attempt cooling to -100 or lower using the 'Faraday method' ( dry ice in evaporating dimethyl ether )

After that , well you know.....liquid gases !

In accordance with the design goals , I am looking at retrofitting some used stainless steel tanks for cryogenic use.

more soon.

That was one of the big selling points of the DFI infinity P965-S Dark.

Almost all Gigabyte boards run solid caps since the 965 chipsets. Only their real bottom of the barrel stuff doesn't have them.
