I've added custom temperature control to the avalon code in the cgminer git master.
It now acts like a simple PID controller trying to maintain a target temperature, which by default is set to 45 degrees, so it will try to keep the temp 43~45, but never going below a minimum fanspeed of 20% as a safety precaution and to maintain airflow.
You can modify this value with the new command:
--avalon-temp
Setting this to something very low will have the same effect as turning the fans up to maximum and vice versa.
If you are not running it from a command line, it can be added to the "More options" box in the web interface (once you have the binary on your machine).
Con,
--avalon-temp is a great feature. Can you be so kind and implement --avalon-cutoff-temp - Gpu style to put avalon in IDLE. I personally run my unit at home with air condition. Outside temp is 40+ Celsius. And i am away most of the time. So if the air conditioner malfunctions you know what will happen

. My home get even fired because of it.
It will be very useful feature for most of us
Thank you very much in advance!
Best
