Thread: GigaByte GA-EX58-UD3 smart fan control, cpu fan speed

    Default GigaByte GA-EX58-UD3 smart fan control being switched off by XMP settings

    SETUP:
    Mobo - GigaByte GA-EX58-UD3
    Bios - F2
    Memory - Patriot Viper Series DDR3 3GB (3 x 1GB) PC3-12800 PVT33G1600LLK set to XMP Profile 1
    Processor - Core i7 940
    OS - Windows XP Professional SP3
    No overclocking

    What should my idle cpu fan speed be? Mine seems to spin at above 2000rpms-2200(idle, core/cpu temp:45-50c) after the pc warms up, and will get up to 2400rpms(temp>48c) and above while running programs. I feel that the fan may be spinning too fast, and is causing too much noise, especially at idle.

    Is there anyway to quiet the fan speed with bios settings? I tried switching the smart fan control in the bios to 'enabled', and switching the setting from 'automatic' to 'pwm'. However, when I reboot the pc, and enter the bios, i find that the smart fan control gets switched back to 'disabled'. The 'pwm' setting change sticks though. Does the bios revert smart fan control back to 'disabled' on every startup? Is this normal?

    Is there anything I can do to quiet the fan?
    Thanks in advance for any help

    Okay an update:
    Bios version is F2

    Ive figured out that the smart fan settings stick when the ram XMP settings are switched to disabled(default 1066mhz).

    Why is the XMP setting switching the smart fan off?

    How can I use the XMP profile 1 settings, and also have the smart fan control set to on?

    You can view your ram's XMP profile using Memset with the SPD tab.
    Note the settings and manually enter them in the bios with XMP profile disabled.

    I've seen several instances where enabling XMP profile grossly over-volts ddr3 ram.

    Thanks for the reply ProfJim. When I get home, I'll give that a try. What do you think could be causing the smart fan function to revert to default with XMP settings?

    I'll try entering the memory settings manually, and hopefully all the settings stick.

    Ditch that Intel toy and get a real cooler. You'll never worry about noise or heat again.
