First post here.
Basically I have an LS1 that I use as a music server (MPD) via a USB DAC to my HiFi and controlled with my iPhone (MPoD). I like to have the unit in the same room but as we know the fan (even on low) is audible. Generally the fan noise isn't even an issue but late at night listening to mellower music it can be heard at the quiet parts.
It seems that the fan cannot be turned completely off. I know fannyd can control the fan low/high according to HDD temp but that doesn't give complete silence.
My idea is:
Hardwire a toggle switch on the rear of the LS1 to completely turn the fan off (when required). Having a script, possibly a modified Fannyd script that activates the blinking "Disk Full" LED when a certain temp is reached, say 40 degrees C (My server HDD temp never goes above 38 degree C with fan on low speed). When the LED blinks I know to switch the fan on. The script will then stop blinking the "Disk Full" LED when temp goes below, say 36 degress C, at which time I can switch the fan off again.
Does this sound feasible? I'm not sure if the fan is required in anyway to cool the CPU or not? or whether it's just a HDD thing... or even if the HDD temp is a good indicator of overall unit temperature (CPU included).
The modified script is easy enough, but as I'm fairly noobish at command-line stuff, I'll need to see on how to actually get Fannyd working
(I haven't had a look yet but I'm guessing the fan is a 3-wire job?.. If that's the case you could use a relay and have it automatically doing it from "OFF" to "Low Speed" bypassing the switch altogether, even even keep the switch in place for "high-speed" when required).
