of course it can be done (that's how we first liquefied hydrogen and helium, and is still used a a precursor to laser cooling), but there would be several problems...
first of all, achieving a flow rate in excess of 400L/s across an area no larger than a CPU would require a whole new evaporator design optimised for high flow... secondly, oil separation becomes complicated at temperatures below -130°C, so you'd need a purpose built separator and an oil that will at least partially flow with nitrogen... third, the hex efficiency drops very rapidly at those temps, and thus we'd need a pretty gnarly compressor (cost being the main problem) to condense the nitrogen... and of course the thing has to be insulated (i mean REALLY insulated), meaning that the setup has to be slightly larger, which will also reduce the efficiency
plus there'd be a whole bunch of other challenges, i haven't actually done the math on this one, but im just saying... it is possible
