    Temperature Chamber tests on mini-ITX boards and PSUs

    I thought you might be interested in this data...

    We have a temperature test chamber where we test all our products -- the other day I did some testing on few popular mini-ITX motherboards and our M2-ATX power supply.

    Cold_start = board will turn on
    Cold_ride = start at 0C, ride temperature down

    While all = boards worked OK on the high tem rage (up to 75-85C) here is what they did on the low temp end:

    Model Cold_Start Cold_ride

    motherboard
    EPIA-5000 -30C -42C
    EPIA-M10 K -35C -42C
    EPIA-MII-10K -15C -42C
    power supply
    M1-ATX -42 -42C
    M2-ATX -42 -42C

    -42C is the lowest temp I can get with this test chamber.

    All motherboards started to freak out around 0 C when heavy condensation occured. Forced air (fan) over the motherboard removed the condesation and no more crashes occured. Please note that I obtained this heavy condesnsation by opening / closing the door several times, this kind of violent humidity fluctuations are less likely in a car and that can be easily dealt with by blowing air over the motherboard (some 40x40 mm fans)

    I did test a seagate laptop drive to -10C and then I stopped, was worried about data damage, that was a HDD with real data on it...

    The tolerances for temperature shown by the hardware far exceeds the temperature range that can be survived by this driver!

    When it gets below -15C or above 75C, I would be more worried about my body parts than any hunk of electronic equipment. Ditto for debates about the G-forces that can be tolerated.

    Still, thanks for posting that information.

    Must be someone talking from california. Anything below 0C is unbearable

    Moscow and inland Russia are in a worse situation... They're looking at -31C around the 20th and 21st of this month.
