    Default EIST Function and lowering idle temps

    Hi All,

    I've read that you can lower idling temps by enabling the EIST function in the BIOS and then setting Windows power mode to balanced. Is this still the best option or is there a better/another way to save some heat while the computer is iding. Thanks

    Enabled all these for power saving.
    You are already using DVID that will lower voltage
    Eist + windows Balanced power saving will lower CPU Multi when at idle.
