For best performance I have heard under 60 is best which is what yours seems to be running around. I wouldn't be worrying too much with those figures.
Well. This is a good new! Thanks.
As it says on the subject, which is the max temperature recommendable for an AntMiner S5?
I have 16 AntMiner S5 works 24 hrs/ 7 days. The max temperature registered has been 66 Celcius in two miners (often the hotter), is it bad? Rest of the day is about 57-62 Celcius and the night is about 57-59 Celcius.
Well, 70. More than that can somewhat shorten the life of the S5, which is probably plenty long anyways, the risk is more burning something off.
Under 60 is recommended for longer life time, under 70 for best stability.
If you want to get the temp down and the noise down, i recommend you use a box fan to blow air through it, through the fins too. My S5 is currently at 48C with fan at 35% with ambient temp at 18c. So +20c and its pretty quiet.
Yes, and now that you said it, do you know how much is the lifetime of the S5 exactly? I can't put me in risk because in my country is very hard find parts.
I've considered it but is an expensive idea. Really, the noise I don't care.
For example, here's a screenshot, sometimes 2-4 miners up to 65C, and 1 miner up to 66C. No more.
