Actually though the machine seems to have a mind of its own you can suggest a maximum fan speed.  From what I gather though it only seems to affect the maximum startup speed as the Avalon will bring the fan to higher speeds if it detects high heat.

Now on to voiding your warranty!

First SSH into the machine using your password:


Then edit the cgminer startup script.


There is a line that looks like this:


100 in there is the maximum fan speed


Now exit the editor and restart the machine:


Like was said above it is recommended you use the -2 flag to voltage to avoid overheating if noise is of concern. Lower fan speeds means higher heat... lower voltage helps mitigate this.

Another option is put the device inside a box and use a dryer vent tube to exhaust the heat.  Helps reduce noise by about 20db.  Another is to grab cold air from outside. Lower heat will reduce fan speed even more.  I had one Avalon running in a shed at 1200RPM for a while.

Good luck and remember I am not responsible for fires, destruction of property or warranty obstructions. 

 

I'm getting an error whenever I type in my password (and it says "Wrong password" when it's not the right one.

I'm stumped
