70F ? If I saw 70F here during the summer I'd put a sweater on. Where I live it ain't hot till its three digits. And too hot to sleep is when it only cools down to 90F outside.
That was mostly my point. The mining rigs make it too hot to sleep. I just looked at the temp readout on my single stage, it says 94 F. It is not attached to a computer, and hasn't been turned on in days.
