My idea was just to change the output fans for stronger ones for two reasons! First, for the summer. And the second was for the inlet fans to work slower and thus make less noise! But I had doubts, because I was advised to work with 1:1 fans!

Hi, I recently bought a T17 and I was thinking of doing a modification I did on an l3+ and I had an excellent result! Which is to leave the input fans at 6000rpm and at 7500rpm at the output! On L3+ I ended up having better temperatures and as a result the front fan works slower and made less noise! I would like to know opinions and if anyone has done something similar! Thanks

I actually run up to 575! The auto-tune chooses the best voltages for each card and then I reduce it from 575 until I leave each chip with few errors! I try never to miss 0.1%!
 I tried to buy these at 7500rpm, because it's been 40 degrees and what actually spoils our machines are the temperatures and humidity, it's not what we pull for it! They always told me that!
 I live in Europe and the boards around here are crazy...I bought the L3+ for 390e and people are now selling each board for 300e!
 I tried using a method that results in a T15 that I have! I cleaned the board with isopropyl alcohol, then I used wd-40 electrical contact cleaner and finally I am moving the frequencies and it is recovering! In this one I already result in two of the boards! Just this third... It might just be luck, but I was left thinking it might be some software error that could lead to a hardware error! Also because in the Kernel it continues to appear "local0.err cgminer[5120]: Get [1]Temp Data Failed!"

Its my Kernal

I got the warning email around 5am! But I woke up around 9am! The L3+ was in protection mode because of a missing fan! when I turned it on there was only one sign. After several attempts, the others started to appear! I still started again today and another 30 chips appeared, but they disappeared again after an hour. Couldn't this type of error be some way of protecting the board itself because of the temperature? And if it was a burnt chip, shouldn't the "X" appear?

Hello my friends! Tonight one of my L3+ fans burns out! When I woke up I replaced it with a 7500rpm one (because it was the only one I had)! The thing is, when I turned it back on, the L3 doesn't appreciate any cards! After many attempts I managed to leave the machine in the state in which the photos appear! Does anyone know what it might be? I've already tested all the cables, I've tested the board one by one, I've already cleaned the flies, mosquitoes and quotations that were inside the machine! You already washed the plates with isopropyl alcohol!

I've shared the images on reddit for you to see as I don't know how to do it here! thanks

Are the home fans at 6500rpm? I have a 7500rpm one here and I could change it to be more rested! I also bought some Y splitters because I was thinking about adding two more fans and that way I had four! But I don't know how much I could spoil something by doing that because it's pulling more energy!

Yea! I tried by network! I will then buy an SSD to test! I saw a person changing one of the pins that are on the main board in order to install the new firmware! This is normal?

In fact, the first one I had to buy was s17! But then I saw several people complaining about the amount erros it made. So I bought a S15... as I couldn't find any at a good price, I ended up buying a T15.

The idea would be to be able to monitor temperatures and fan speeds! I live in one where temperatures at this time of year range from 26 degrees to 34 degrees! And there are hotter days. And the firmware I have on my L3+ I can handle these things and also have options to put the machine to sleep if the temperature limits pass the desired! After that it also manages the chips, to improve performance and when possible to lower energy consumption!

Regarding braiinos I sent an email to confirm if it is possible to install on a T15! And thank you for the information! About Hiveos what happens is that the installation in the middle says that it is not possible to install! I got the feeling that it was blocked for some reason! Therefore, it is most likely blocked to different frimware. With this link I could unlock the machine and then install the version I want! right? I wanted a firmware to be able to control the machine for some reason, away from home! And if possible have a good auto tuning and have a manual chip tuning!

Hi! I'm new to mining on Sha-256! I have another machine that is for Scrypt and is mining Litecoin! So my doubt is this, I bought my first Antminer T15 (which unfortunately had some defects, but fortunately the L3+ experience helped to overcome it) now I would like to have a more complete Firmware! As I'm using Slushpool, I think BraiinOs would be the most suitable (but this option, I found a note saying it doesn't support the T15) so I tried HiveOs (which is what I use on the L3+) but when I try to flash from the error file! So I would like to ask what is the best firmware option for an Antminer T15! (if it is possible to be able to move the machine when I am away (such as on the mobile phone per application))
