Re: POLL: What temps & fan speeds do you maintain for 24/7 mining?
But when the machine hangs for a couple of hours (due to too high overclock, unstable gpu etc...), the extreme low temp will hurt the fan bearing, those fans have become so noisy recently that I plan to take them apart to re-oil
If you ever want to rig up a "thermal protection system" it could be as easy as a 100W lightbulb rigged to a thermal switch which cuts on/off at temp below lowest operating temp and above freezing. Put the thermal switch near air intake. When cards are running enough to keep temp up the switch is off. In a failure, temp drops, switch closes, and 100W (maybe 200W) light bulb turns on keeping rig from freezing.
Plus saying your rig "outdoor ready" due to a "Thermal Protection System" just sounds cool.
