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?

My bad. Check mg_custom_mode. It's human readable.

Edit:
Just note that under very low fan settings you might stress the back side of the miner and it can cause termal shutdown. Theoretically it should work since the system scales on both dc2dc and asic temperature. be careful when touching the back side of the miner - it can become very hot

do you mean this set of numbers?

Temp Front / Back T,B
38 °C / [b/74,71 °C[/b]

if so what is low enough?

right now my room temps are very high due to 74f temps in Howell NJ USA
