Long term LN2 cooling?
I googled but didnt get an answer. Is it possible to do long term cooling with LN2 or liquid helium? By long term i mean months to years. Basicaly wondering if you can have a CPU run say at 7 ghz on LN2 24/7. This is ignoring cost too...

Sure.... but cost is always a factor. You also would need daily deliveries of the liquids and ensure good ventilation. If cost wasn't a factor, you could build a $500M magentic/laser bottle to feed super-cooled helium atoms to your pot.
It would be cheaper but not as good to build a cascading phase unit.

No sir. It's just not cost effective. And assuming cost doesn't matter you would be filling it up often. Very annoying if your playing a game. Plus a chip running at 6ghz + for awhile probably want last that long.

Yes it can be done.
No its not practical. Yes this has been asked many many times before.

There is no way your going to be able to LN2 your system for long term. It is very expensive man. Just stick with some nice water cooling or a Phase system.

Hi, i'm Barry Scott!

Surely with a chip at 7ghz, voltages are going to cause electromigration, something which coolness can't prevent?

I think the closest thing to a feasible long-term subzero cooling solution would be a phase change cooler. The Prometeia Mach II GT comes to mind, but I think it's discontinued.

well guess that might have to be his solution, I wouldnt run over 4.2 - 4.4ghz tops on an i7 920 anywys, no idea what his specs are, it certainly would save money
also ive heard ideas of running a loop with antifreeze and keeping a constant amount of dry ice in the res, does this work? what type of pump could handle this?
