I will try again!
Use mineral oil for cooling and sound damping. The build works but the fuckhead moderators deletes the ideas they don't like!

Topic: S9 Temperature Spiking Issue (Read 167 times)
Op isolate the bad board.
And run two boards. You need to clean all boards and fully remove them to do so.
Tricky boards happen. That board moving up to 135+ is pretty much a death rattle.
Good s9s run with an error rate of under 0.0050%.
That miner is up to 0.0271% which is okay if that temp was not jumping up to 135
The problem has happened to me and most often board dies once it does this often.

Thanks for ideas, I think it's the sensor, just based on how fast the temperature spikes and then returns to "normal" and that it takes 10mins after turning on for the first spike. And runs normally in between spikes. Do you have a picture of the temp sensor or anything to help me find it? Or is it something that will be obvious when I pull out the hashboard?
No, I don't have an image for temp sensor I'm honestly looking for this and a hashboard diagram for a long time but no one sharing it.
I just heard that the temp sensor can be found in the middle of the board on the back.
How about moving the hashboard in the middle slot and maybe it will help to remove the temp spike I just got the idea from this reddit post below.
- Bitmain S9 higher temp on one hash board. Also much higher HW errors on Chain #6. Normal?
135 chip temps are always a bad temp and according to "Miner normal operating temperature range" it is a maximum chip temp but according to one of your image it shows 149 which is too bad for your hashboard. It seems a faulty temp sensor if you are getting some temp spike.
Can you try to find which hashboard is getting high chip temp you can check this guide below?

After you find the one hashboard which is getting high temp then try to clean the hashboard or look for the temp sensor to clean I don't know where it is located on the board but I heard you can find the temp sensor on the middle back of the hashboard then test it again.

After a few years of operation you might just be seeing signs of wear and components may just start failing. I've never run s9's but when's the last time you checked and cleaned the miner? If it's all clear then you have to take the above advice and figure out which board is faulty and inspect it.
You can do so by disconnecting and reconnecting boards until you isolate the problem. Then you'll need to do a visual inspection for anything out of the ordinary like a scorch mark on the board or something loose. Bonus is that you can still run the machine off 2 boards or find used parts for replacement as they are EOL gear.

I cleaned them out a few months ago with air cans and leaf blower, but I didn't remove any hashboards, so I guess maybe that would be a good idea to do to all of them just in case there is any residual buildup.

My S9's have been mining away uneventfully for a couple years. Then last week started noticing a lower hashrate with one of them and when I investigated I noticed some temperature display issues. Not sure if it's actual temperature or maybe its a bad sensor? Seems to change pretty rapidly.
After initial boot-up:

Notice the top one has a lower overall hashrate.
Miner status of that one:

At 40 HW already.
A few minutes later it then does this:

Miner status again:
https://imgur.com/kxkRPzX
Temperature jumped drastically.
And then on the next page refresh
https://imgur.com/NQiZlSG
So over the course of 30 seconds it jumps some 50+ degrees and then back.

I don't really know what to try next or what needs replacing. Any help appreciated. Thanks.
