[philipma1957]

it says they are too hot.

so is the room hot.

are the fans set to at least 90%

my board temps are much lower than yours.

46 41   67 67
46 39   69 66   
47 42   70 68

it says you are over 95

[mikeywith]

Dude, you are you going to fry these expensive gears, each of these gears costs above $7000 to buy today, and you are torturing them.  

Code:

2021-01-20 18:16:36 over max temp, pcb temp 81 (max 80), chip temp 96(max 95) pcb temp rise 0 chip temp rise 0, total_exit_failure 0

Both miners show PCB temps of 81 where the maximum temp of S19 is just 80, and one or more chips are at 96 degrees Cellius, they shouldn't be close to the max by any means, when the max temp is 95c you should start to worry when the approach 85c, you need better cooling, it seems like you are not exhausting enough hot air and it's going back to the miners, for starters, try 100% fan speed and see how it goes.

[Snowballx]

Thank you guys I replaced the AC in the room and yes the room was so hot without exhaust and weather where I live is such a hot as hell.

[mikeywith]

Thank you guys I replaced the AC in the room and yes the room was so hot without exhaust and weather where I live is such a hot as hell.

I used to think that I need an AC to cool the miners down where I live, temps go over 40c in the summer, but I came to understand that sufficient airflow is more than enough, you could add an AC (if you don't care about the power bill) but without exhausting the hot air fast enough, you will always run into over temp issues.

[Snowballx]

am living in Middle East so some how in summer I'll face over 50 degree for sure what am planning to do adding 2 AC's 2.5 ton or 3 ton one would be facing the machines and the other one would be in the back the room is small for the small farm I have it's only 4 S19PRO for now might jump to 8 as maximum later the room size is 4x4msq so cooling it won't be an issue the problems am thinking to face is what if it really need to be exhausting the heat even with the two Ac's running 24/7.

[philipma1957]

lets say you do not exhaust heat.

each s19 unit is 3300 watts which is about 13200 btu.

so 4 pieces are 52800 btu.

a 1 ton ac is 12000 so if you commingle the ac with the hot air from the miners.

two 2.5 ton ac units can cool 4 s19pros. as they would have 5 x 12000= 60000 cool btu vs the 52800 hot btu.

you have to vent the hot air.   think about the summer heat of 50c or 120f.

only 7200 btu is left from the two 2.5 ton ac units.

[Snowballx]

himmm the truth sometimes are a dream breaker what should I do with this small room can you help me more how can I exhaust the heat out of this room cause am not planning to stop the mining.

not sure if I'll have big exhaust fans here and will keep the room clean with our dusty summer.

"the summer months are June, July, August and part of September. These months are mostly dry, HOT and dusty! Temperatures exceeding 48c, dust lasting for over a week, all in summer."

NOTE: I like how you miss that click from btu to btc. appreciate your times guys.

regards.

[philipma1957]

Okay 1 s19 unit expels about 500cfm.

so I think this will do 2 units and put a fan on the end.

https://www.homedepot.com/p/Master-Flow-12-in-x-25-ft-Insulated-Flexible-Duct-R8-Silver-Jacket-F8IFD12X300/202562743

https://www.ebay.com/itm/12-Inch-Inline-Duct-Fan-Vent-Exhaust-Air-Cooled-Hydroponic-Fan-Blower-1200CFM/121181455603?

So 2 tube and 2 fans could pull as much as 2400 cfm out of the room.

Ac >>>>> miners >>>>> tubes >>>>fans>>> outside

[Snowballx]

order placed thank you so much sir for your time.

[mikeywith]

how can I exhaust the heat out of this room cause am not planning to stop the mining.

You can do a split-room setup, check my mini mining farm, I initially had an AC there but it was removed later own and I added more fans both on the intake and the exhaust, this design helps you control dust and noise by trapping all the hot air in one place, make sure you don't have pressure imbalances.

[Snowballx]

that post you just share is full of good information I just saved them and will start pressing the new mining room cause my miners now in my friend house and am planning to move them to mine in the middle of April and this post would help me a lot building a better mining area.

Appreciate your support guys. can't thank you enough.

[kalafe2006]

It's work under 2 cooler

[BitMaxz]

i have an S19pro , it's work one minute then will power off. anybody know whats the proble

Can you post the whole kernel logs let me analyze them for you?

If you have a limit then you can try to paste it here https://pastebin.com/ and then paste the URL here.

What is your room temperature?

If the error on this "stop_mining: over max temp" try to manually set the fan speed to 100 you can find it under miner's settings and set it to normal mode.

If it doesn't solve your issue try to upgrade it first with the latest version available on Bitmain and test it again.

[kalafe2006]

Thank you my friend

My room temperature in under 30 centigrade

I update it several times
Try to set fans on 100 percent  and will send you complete kernel log 

[kalafe2006]

I set fans on 100%, but didn't work more than 1 minute.
It's my kernel

I wonder what is the problem with people not reading.

See, it says so in caps, exactly the same as op:

ERROR_TEMP_TOO_HIGH: over max temp

Why do you need others to tell you what your miner is telling you and previous posters even talked at length about?

The S19 needs 500CFM. Else check if your fans are all working correctly.

Its not "just fans", you can't just put the miner in a closed room. When we say 500CFM, that means air coming FROM OUTSIDE to the miner and then again TO OUTSIDE, A/C is irrelevant, move that air!.

[kalafe2006]

All fans work correctly in 500cfm
Room is not closed
Air come in and out in best positions
Other S19PRO work in this room correctly,just  this one has problem
