Why would heat from a Bitcoin miner be dangerous. My undervolted S1s run at only 40C. That's less than laptops, playstations, etc. I've never heard any report that heat from computers can be dangerous.
Heat from computers or any electronic devices will not harm you.
But the chemicals released from these extremely heated electronic components are harmful inhalants.
This is a documented stuff and papers are available on the internet.
From normal electronic devices like television, refrigerators, etc they are very much negligible.
Incase of these mining hardwares, their build quality is too low due to low life expectancy.
But they are running at extreme conditions for mining so the chemicals silently released are multifold than the others.
Interesting,never really thought about the health effects. I'll have to look into this. SO what you are saying is that anyone who has mining hardware regardless if its for mining or heat is putting their health at risk. If the risk are serious, I guess there are going to be some very sick people in the near future.
Perhaps I'll move them out to the back shed if possible to take the edge off the cold. Have to keep it heated slightly to keep the moisture down. Or perhaps it's just time to let them die off before I do, LOL!
