Also the problem with LN2 is that you're putting a lot of heat into something that wants to expand into a gas very much, behaves oddly in contact with heat, and is already below ambient. So you've got pressure problems, reliability problems, and since it's below ambient you need absurd insulation to stop water from condensing on anything and letting the magic smoke out.

 

Ln2 is used on horizontal mounts with great insulation and ventilation in what's basically a giant open-topped pipe and then it's just consumed as it boils off, the boiling off is what absorbs the heat and carries it away. If you want to actually KEEP your ln2 somehow you need a way to dissipate enough heat to safely recompress it to a liquid and pipe it back in again, which is basically just using a refridgeration system on your CPU and ridiculously inefficient.

 

The only active cooling systems that are really worth anything are peltier chips either on a regular HSF, which will basically keep you right at ambient, or a peltier chip on a water cooler radiator keeping the water right at ambient. Any cooler than ambient and again you wind up with massive condensation problems.
