Yes, Americans like myself try to think of it in relative terms:

"30C?! Is that freezing or boiling? Eh, more like half way. Ok. So, twice that sounds too hot for a miner..."

Anyway, what surprised me was the low, sporadic hashrates I've never seen from this Avalon6 before (e.g. 2~2.5 vs. the usual 3.5~3.75)
