No, not some exotic cooling solution...
Just an idle server running out in the garage 🤷

@bbrks Had one of those last year before the basement got a properly insulated door. I saw 5C temps during idle periods.

@kevin It's fun to see, until the ambient temperature alarm starts going off for being too low! :)

This has caused me many problems in the recent cold snap (-8C ambient)

1) Dell PowerEdge servers don't differentiate between ambient temp alarms that are too high vs. too low (just out of range)
2) The fan curve doesn't handle negative temperatures well (the fans ramp up to 100%, guaranteeing the temperature remains sub-zero as much as possible)
3) Server rack organisation is critical to keeping mostly idle servers from getting anywhere near dew point and in condensation territory (perhaps contrary to popular convention? the hot servers being at the bottom manage to keep the top ones mostly idling warm)
