    under the part where the rotation of the fans is indicated, there is no possibility of setting a percentage speed.

    Hello, 

    the hash rate is  normal and this version doesn't allow to adjust the fan speed.

    We don't suggest you to revert to the old firmware because it's easy to get virus.

    The miner status is good and we suggest to keep this version.

    Hello,

    thanks for the support, I have 2 antminers, but one antminer has a higher fan speed.
    As a matter of noise, I need to set the fan speed to a fixed percentage. The place is air-conditioned at 19 degrees centigrade, so there is no danger that the chips will heat up.
    I would like to know how I can do it, if there is an alternative solution to downgrading the signature software and, if not possible, if you can send us the previous firmware for the downgrade.
    thanks a lot

    Hello sir, 

    We don't suggest to download the firmware, it's highly risk to get virus.

    If you determine to do so please refer to following link to check if there's the document you need

    https://service.bitmain.com/support/download?product=Antminer%20L3%2B%2B

    If you can't find the firmware you need here then I'm sorry we can't provide other files either.

    Sorry for the inconvenience caused and thanks for your understanding!
