Well. This is a good new! Thanks.
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.
Still consider it is good?
I like to keep mine under 60c but its not bad per say. I just like to keep air blowing sideway because certain component will be much hotter than 60c when it read 60c. And AntminerS5 have been around for a while and typically unit that have lasted for a while should last quite a while longer.
For instance i have S1's which are still stable and they have a lot of use by now.
