As in constant cooling?

It would not be very practical as you would be needing to constant top up the chamber, also I am not sure on the longevity on system components.

Not without an expensive and fairly elaborate setup.

Condensation, etc. becomes quite a big issue in day to day running never mind how long components can survive under those conditions.

For extreme cooling on a longer term basis then probably a phase system that stays above the dew point is more practical.

The chips may do well under high end cooling, whether it air or water / chilled water.
 
I'd assume they'd also give you the best chance of getting a decent overclock on air over a random chip.

There are other high end cooling setups that aren't as extreme as LN2 that can be used for more sustainable extreme cooling though have gone out of fashion a bit like phase change/peltier setups.
 
Those chips are aimed at benchers seeking to hit high clocks under extreme cooling. But for the average overclocker, you can still get much higher low voltage overclocks than you would by taking a chance on a normal retail chip using everyday cooling. Take the delidded 4770k bundles ocuk sold a while back, 4.6ghz was pretty much standard for theese but I know of several guys I game with who easily hit 5ghz for 24/7 use. Haven't seen that many 4770/4790k's that will do this

I understand what you are saying but you only get a 90 day warranty with them and that put me off. If they offered 12 months it would give you some peace of mind.

Yes, with a cryostat/cryocooler, but would cost you several thousand pounds. You'd end up with a similar system to that in MRI machines, where the liquid nitrogen would be pumped around and recondensed using a motor - bit like a fridge.

Much easier to get a "normal" phase change cooler and keep it at -50 C ish (compared to -210 C).

Can usually get results as close as make no odds for 24x7 running without even going sub-zero - usually takes fairly drastic reductions in temps for every last "1%s" when trying to get a WR. Back in the day when I did take benchmarking a bit more seriously could usually get to levels that would be in the top 3 while working to a target of ~14C.
 
I bought one because it wasn't much extra than a standard chip and I knew that it would give a good overclock at sensible voltage and temps. Mine runs day to day at 4.9GHz under a mid-range closed-loop cooler.
