I think it's neat that they did that, but for some reason I no longer have any interest in experiments like that. I remember watching overclocking websites when some brave soul managed to push a Celeron to 800Mhz and survive. I guess advancing technology just takes the fun out of it.
like i would want a dewar of that stuff next to the desk!
i have done peltier and water but thats as far as i will go.still running a bp6 with 2x celeron 300a@504. 24/7/365.stock vcore and air.
