Acceptable temperature and humidity range for a server room

Hi all,

On of my clients keeps their single rack mount server in a comms room in a large shared office block.  They are getting regularly audited and IT is now becoming part of this audit.  They have been asked to provide regular temperature and humidity monitoring checks which haven't been happening and they have asked me to start monitoring (albeit crudely) but before I do this I wanted to know at least what the max and min safe temperatures and humidity levels should be within that comms room.  Is there a fairly generic safe range I can quote?

    designed to be operated in "room temp" - ie all computers are desinged to be run somewhere between -10 and 35 degrees celcius.
    Your server room needs to keep the temp down similarly and the lower it is then the more headroom you have for failure of the aircon.
    At really low temps you definately need to watch the humidity or you will get condensation.
    I typically go for something in the low 20s

    Hi Adam,

    This is a good question and no official rules exist on it. The Temperature and humidity best practices depends of your server room (Datacenter, small room on an office, Great server room ...) but also on your city and weather environment, specially for the humidity. For example, it's more difficult to control the humidity of a small room in a corner of your office than on a datacenter with hermetic room and complex environment systems.

    For a basic server room, we recommend a humidity range between 40% and 55% and temperature range between 20° Celsus and 30° Celsus, the better temperature/Energetic cost I think, is 23/24° Celsus. But this temperature range for the server room is not the most important. It depend on which method you choose to maintain a good temperature on your room and the air-flow you have.

    The Important thing is that your hardware must not go out of the recommended operating range (that is specified on each hardware datasheet). Generally, your hardware must not go after 40 or 45°C. After that, hardware damage can occur.

    There is below few interesting article for that :
