Avalon 1166pro always restarting

[jonbringus]

I bought a couple of these used awhile ago and they've been good until now, this one restarts every 5 minutes. From the logs echu and ecmm seem abnormal but I can't find any specific codes for the errors. Ignore any fan related errors as I removed the 120mm fans for a 8" ac infinty fan.

Have you noticed the system status?
It shows over hot meaning it's overheating which is why it keeps restarting MTmax is pointing to the middle board the overheating came from the middle hashboard.

Why did you remove the fan it is not running properly I suggest plug the fan again it should fix your issue and lets see if the MTmax on the middle board drop.

I removed the fans because it was way too loud, it's a common "mod" to attach a shroud and remove the fans. I've used the 8" fan on various antminers and haven't had issues. I've heard the big fans actually flow more air cfm than the stock fans. On the dashboard it shows temps in the mid 50's which seems fine and is cooler than the stock fans, I remember it being in the low 70's before

Well, the logs say it is overheating it's above 85c which should be the temp limit for this unit according to Avalon.

Avalon units are not the same as Antminer the fan you use on antminer might work for them but not for avalon.

Would you mind replacing back the original fan in this unit and then check the API logs again under MTmax to see if the middle board temperature drops?

[ZeusBtc.com]

The log shows:

Code:

BitMaxz is right. The chip temperature on the middle board is too high. One chip's temperature reached 107, while another's reached 116. So, you need to check and repair the hash board in the middle.

seems you both were right, I switched the fans back 2 days ago and it hasn't restarted since. I'm a little disappointed because it was working so well until now, guess I have to deal with the noise. thank the both of you

Now we see MTmax on the middle drop a lot from 116c down to 78c which is a big improvement after taking the original fan back to the unit.

Why not build something like noise reduction if you can't handle the noise for long? or soundproof box you can DIY for this unit if you want to reduce the unit noise.
