Всем привет.
вот на англ ветке нашел "рецепт"
Hi guys,
After hard work at trying to understand how the antminers S4 fans works (40 hours of my time) , I have finally been able to change the S4 fan speed by changing software.

This allows to effectively decrease the noise from the s4 AND to decrease the power consumption by a maximum of 100 watts (expect 30-50 watts).
It should not be used if the temperature is > 55°C. Check that the stop miner when temp is over 80°C box is checked in the configuration page.
If this helps you, consider my bitcoin address :

I have modified the bitmain_spi.ko file into two others binaries which gives differents fan speed.
First version with lower fan speed:

Second version with much lower fan speed: it should not be used if the temperature is > 55°C. Check that the stop miner when temp is over 80°C box is checked in the configuration page.

The original is here if you need it :
https://mega.co.nz/#!NJtxUToZ!KyTOlad--U1JTddV9sq0XdqBhqygmdIZ0ulV1iLuooATo use it :
Change 192.168.0.16 with the Ip address of your miner
scp bitmain_spi_fan_6.ko root@192.168.0.16:/config/ #Copy the file to the miner
then ssh to the miner :
ssh
root@192.168.0.16then :
cp /lib/modules/3.8.13/kernel/drivers/bitmain/bitmain_spi.ko /config/bitmain_spi_original.ko #Makes a backup
cp /config/bitmain_spi_fan_6.ko /lib/modules/3.8.13/kernel/drivers/bitmain/bitmain_spi.ko # Copy the new file to the good place
cd /etc/init.d/ #Change directories
./cgminer.sh stop # Stop cgminer
#Wait 1 seconde
./cgminer.sh start # Start cgminer
#Wait 30 secondes
Check the web page at 192.168.0.16, you should be able to see the new lower fan speeds

I did not do that for free

; if my new binaries help you and you are satisfied, help me by sending some bitcoins to my address:

Warning: Do nothing you don't understand ; No warranties whatsoever are given by me ; this could not work or be useless ; this could burn your S4 or make it useless ; this could void your warranty with bitmain.
правильно ли я понимаю, что смогу всё это сделать по инструкции прямо в винде в командной строке.. и потом если что-то не получится, смогу все откатить назад ??
в общем, интересуют подводные камни описанной выше процедуры Smiley
Спасибо
