No, 68060 CPUs have a very high heat tolerance.
Neverthless I've noticed a big difference of temperature between a 68060 closed inside the trapdoor and a 68060 in an opened trapdoor.
Probably if you can mantain the CPU at a lower temperature, you'll give more life to it :-)
Non I'm building a simple "system" to keep fresh the Blizzard. If you want, I can send you some pictures or sketches of my little project :-P
