Well you can go as low as -196c max on ln2, but most chips except PHII can't take it. The few i7 that can are reported to get funny with the IMC. Honestly a cascade is cold enough for i7, but you don't get the temp control like with ln2. That is what makes it king. Got a CPU that cold bugs at -40? No problem, use ln2. Cold bug at -62c? Use ln2 cause dice don't give temp control. Get it?
