i can confirm the temp problems without internet. just today my internet went down for about 30 minutes..
they started beeping as usual when it detects no internet and all the fans turned off. i pretty much ignored it and went on doing what i was doing. after a few minutes i noticed the s5 beep turned into a solid tone.. ive never heard that before.
i went to check it and when i touched the heat sink and it was so hot i couldn't put my finger on it. the fans were not spinning very fast and really hot air was coming out the back. i instantly shut it down.
the internet is back on again, it seems to be working ok.. today was the final day of my 90 day warranty.. i hope i dont have any problems because of this.
this is a problem and a potential fire hazard.. had i not been home who knows what would have happened.
i went and put the fan on a molex adapter.. its not ideal since its now at full speed.. but if the internet shuts off again the fan wont stop.
email bitmain START TALKING TO THEM NOW Bitmain is already working on this issue, so wait for new S5 firmware. nice I hope it's fixed, when ever I leave home, i turn off all my S5 . for the over heat reason . i ended up just pulling the blue wire on the fan for now.. i can always put it back in when its fixed.

Shocked we haven't heard of burnt up miners because of this. I was the first one to report/post about this issue many pages back and it still being discussed. Since I put all my miners on the "always on" molex connections I don't need to worry about any overheating again. I also removed stock fans and use two Noctura Industrial fans which do keep temps in check, even in this 95 degree temps in NJ. Worth the extra money. Those fans have a 6 year warranty and have been superb from day one. They will outlast the miners and then I'll use them in a couple computer builds. All PWM too.

I will remove 4th pin from S5 fan to keep it running at full speed. Official reply is that they're working on the issue.

A week ago my second S5 arrived. Exactly the same as any other S5. But, when we turn it around and remove the plastic side panels we uncover this: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fwww.pohrani.com%2Ff%2Fn%2Fz7%2F1cTN4zbK%2Fdsc5282.jpg&t=665&c=38blZP99RqZYEQ) Very cool, perfectly sized heatsinks outside of the hashboard. Can someone please tell me where can I order such a heatsinks? Or probably some other heatsinks with 12x8 mm base and 10-19 mm fins?

Had a scare today, summer has arrived and my active miners started screaming (was very warm in here)! I was sacked at the time, but checked and found it was virtually every running miner and ended up shutting them all down.
Later got up and couldn't get any miners to function properly (access worked, but status screens remained empty or else each pool was dead) and that includes miners that weren't previously running -- none cooperated! Tried various things and discovered part of the problem was the TP Module communicating to two powerline networks had stopped communicating (seemingly overheated!) Swapped in a spare, whereupon the utility reported the network whole, but the miners still didn't work, power recycle and reboot still didn't solve the problem. Finally occurred to me to unplug, wait some twenty plus seconds, and replug each of my six LAN switches. All of a sudden, the miners started reporting normally.
Now, all is again fine! Something to consider when trouble shooting! (Also dropped the S5 clock rate from 300MHz to 287.5MHz in hope of less likelihood of repeat. Outside temp was ~87F with windows open to help heat escape.)
It's a good idea to power cycle the switches periodically. Lets them remap the ports and come to their senses. Especially if you're running cheap switches. It's always nice to pick up some $20 switches to keep costs down when you're investing in new gear, but when the dust settles it makes sense to invest in high quality switches.

I always find it amusing that a product that is priced in USD, for which virtually none of it's inputs (e.g. chips, assembly, case, controller) are priced in BTC, somehow then is influenced by the price of BTC? I think they changed the price, "because they can". Who else are you going to buy from, today?

you noticed they never lower it when bitcoin drops! Bitmain is sucking every bitcoin they can get because they are going broke ! Its like milking the cow for its last bit of milk Because you know the cow is going to die any day now. way to go That's pure greed if you ask me. but then again that's business. Don't lower the price just keep raising it that's real cheesy bitmain ! what are your thoughts foolish or otherwise ?

Google Cache June 15th, 03:20GMT: $340 / BTC1.434 = ~$237/BTC. bitstamp: ~$235/BTC Current: $360 / BTC1.432 = ~$251/BTC. bitstamp: ~$252/USD. So while they price their items in USD and let the BTC amount fluctuate along with minor exhange rate fluctuations, there's thresholds where they adjust the USD price to keep a roughly same amount in Bitcoin. ( Next to more manual adjustments as we've seen in the past. )

I think you've nailed the state of Bitmain quite well. I've become thoroughly disgusted with their business practices.

I am ! Buying from Coinbase ! True. Coinbase Exchange has been very good to me lately. I also agree with the other poster. I've watched and the price never changed when bitcoin went down. So no, it's not tied to bitcoin.
