So, I do not know if this is the right place to post this question but I might as well ask. I've been wanting to learn how to get into liquid cooling my cpu with liquid nitrogen (for exetreme overclocking) and my question is, is there any place to buy consumer liquid nitrogen for my project. Thanks!

You wouldn't necessarily liquid cool with liquid nitrogen - you would pour LN2 into 'pots' that are essentially bolt on blocks for your PC that literally hold liquid LN2 while it boils off. But, I would start at a welding gas supplier and see where that leads you. I would imagine that LN2 actually requires some form of license in order to procure...at least in any significant volume.

You have A WHOLE LOT of reading and info to go through, BTW. This is is a cooling solution for those running very custom BIOS's, custom hardware with modified power delivery systems and for short-term benchmarking only.

I'm pretty sure welding supply stores have liquid nitrogen to buy. You can get cans of the stuff from medical suppliers, but I think you are looking for a bigger supply. You do know how potentially destructive it can be to cpus right?

Otherwise, if you're looking for long-term, sub-ambient liquid cooling, you should be checking into some of the more advanced forms of Peltier/TEC liquid cooling systems. 4ryan6 is one of our forum members who has a long-term setup like this, although I think the photos are broken on his page: http://www.tomshardware.com/forum/282844-29-peltier-water-cooling

Some quick research implies that there is no licensing required in many locations to purchase LN2. HOWEVER, I believe that any seller worth their salt is going to question you pretty harshly to ensure that you will be using it safely. If you haven't started this journey with dry ice, I think you are going about this the wrong way. Typically most of the best overclockers start by using Dry Ice and then once they are really pushing hardware switch to LN2 or even LHe. Jumping straight to LN2 is not a good idea IMO

Excellent points, I had forgotten about using dry ice first. Heck, even using compressor-cooled coolant in normal watercooling. (That's how I regulate fermentation temps in my beer brewing setup :) )

If you already have experience with compressor cooling. That may be the direction to go for you. You can still achieve very cold temps even sub zero and once the system is set up and running is easier to maintain those temps than dry ice or LN2.
