Topic: S5 Miner Temperature Sensor issue (Read 1011 times)
Totally forgot about the customized fan speed lol! I'll do that. Thanks again for the help
Thanks for the tip. I checked each chip and they range anywhere between 59C - 38C (of course the ones closest to the fan were coolest). Overall, one board is definitely running hotter than the other but none of them reflected the 90C temps that the miner dashboard was showing. At this point, it looks like a busted sensor. Ideally, I'd rather not have the fan running at full speed especially when it's not needed. Any ideas on replacing the sensor or manually reducing fan speed? Thanks again for the help.
Miner Configuration -> General Settings -> Customize the fan speed percentage -> #
If you do not have that option you will need to flash the firmware to the latest version;

You upload the tarball, you dont extract it.

Hey all,
Turns out the board is running hot. Using the thermometer laser, I got readings of 124F and 85F. The Antminer dashboard reading said 84C and 47C respectively before I turned off the machine. Any ideas why one side may run hotter than another?

Thats like 50C, thats not hot at all. In fact thats cool. Did you check with your laser every chips and the sensor area? (Dead center) Set your thermometer to C, its confusing in F.
If every chips read that cool, and you go all over the board and you dont see any hot spot, then the sensor is just busted. Just be sure you check the right board, so check both.

Thanks for the feedback all. @VirosaGITS, I'll try that out and fortunately, I have a laser thermometer handy. Just for clarification, are you referring to the screws that hold the sidings on the machine?
The PCB has screws all over the board to push the chips against the Heatsink. Just check every chips and try to see if one flares up to 100C+ thats what happened to me. If so tighten the screws a bit that would push it against the heatsink.
If that doesnt work it could be a bad paste job.
hmm ill have to take at look at mine and do this. some of the boards have a 5-10 degree C difference between sides. never thought it would be a loose screw.
5-10C is normal, the boards are not mirrors, they're identical. The temps difference gets better with 2 fans though because a bit more air blow on the hotter sensor that way. Its best to check with a laser thermometer to see if any chips are actually overheating.
The sensor is not to be trusted too much. When the censors is at 60C the chips at the end are already close to 80C. Which is perfectly fine.

Isn't there a way to turn off the safety heat shutdown?
If you feel comfortable doing that, it would be the simplest solution.

Did you like, read his post at all? He says he already did that and it work, but he is worried of causing damage to the miner over time. Its very possible.
Wasn't paying complete attention to be honest.
I suppose it's worth looking into since the fans use the temperature reading to adjust their speed.

Hi all,
I have an S5 that appears to have a quirky temp sensor or a really hot board. The temp is causing my miner to shut down when the temp crosses 80C which happens about 30 seconds into booting up. The temp readings are 53 and 80+ which I suspected was incorrect as the miner is sitting in a vented 50 degree room and for the last 10 months has never had a temp this high. I have other miners in the room and they've been running fine. When I turned off the "Stop running miner when temp is over 80C" option, the machine runs and holds the proper hashrate but the temp reads 90 degrees on one of the boards. While the miner technically works with this option off, the fan is cranking more than it should and the board may be hot as heck (assuming the reading is right). Either way, I'd greatly appreciate any help the community can provide in troubleshooting this.
Thanks in advance!

See if there's any lose screw, try to tighten but not too hard. What you'd need for this is a laser thermometer. With mine i was able to see where the heat was coming from and i figured out one screw was not tight and the chip was not touching the heatsink much.
