Is there anyway to cut the fan speed to less than 40? I plan on under clocking and am interested in reducing noise.

edit /etc/mg_custom_rate via ssh

looks like this is a new file

miner-FL1444045011# ls mg* -1
mg_custom_mode
mg_custom_mode_sp20
mg_custom_mode_sp30
mg_disabled_asics
mg_disabled_asics_sp20
mg_disabled_asics_sp30
mg_generic_psu
mg_psu_limit
mg_try_12v_fix
mg_work_mode
miner-FL1444045011#

What is the format to include the 30% fan rate?

Even better you could just change the PHP file so that you don't have to keep manually editing the mg_custom_mode_sp20 file...

Old code

Code:

New code

Code:

You can find this in /var/www/SP2x/settings.php around line 312 in Sp20 firmware version 2.5.27.. or you could probably just search the file for fan_speed_select.

Careful though. Everything in the www folder is not persistent between reboots. Looks like one needs to modify more than the php files to make it persistent.
The configuration files in /etc, however, are persistent.
