    Hello All

    I have swapped out the stock HDDs in both my laptops for SSDs.

    On battery, the machines run silently except under load but as soon as I plug them into the mains, the fans kick off and stay on.

    I've updated the BIOS on both machines, changed the (minimalist) fan auto/low settings there and tinkered with the Windows power settings (min CPU state, system cooling policy) as per the instructions from elsewhere on the net, but this behaviour persists whatever I do.

    I've also checked the heatsink and fan for dirt on both machines.

    Is there anything else I can try?

    It's just interesting that this is on both machines but only with the SSDs installed - if I swap back the HDDs, the fans are far more passive.

    Toshiba Satellite with OCZ Vertex.
    Samsung Q330 with Intel X-25.

    Also - I now have the 'Consider replacing your battery' problem on the Toshiba (3 years old) and continual mis-reporting of battery time remaining on the Samsung (1 year old).

    Thanks

    Hi axial and thanks for your reply

    I've generated an energy report on the Samsung - no errors and I only get the warning about the wireless adaptor's power policy being set to max.

    Hmm...!

    Could it be that some power-related settings somewhere in the hardware of these laptops are optimised for mechanical drives and are inappropriate in some way for SSDs?

    If I were having this problem I'd comb through the forums on SilentPCReview, as those folks are great at understanding how to keep stuff quiet and yet achieve good performance:

    I wonder whether your laptops need updated drivers and chipset information to deal with an SSD, I can well imagine that some power-related settings would be influenced by whether the drivers and/or O/S actually recognize that an SSD is installed, and if they don't recognize it they might set the fan speeds to max just as a default.

    aha -- I knew I'd seen a similar issue, it's probably this issue:

    Good of you to dig that up!

    I've been checking for Intel firmware releases frequently for the X-25 on the Samsung, and I'm current, with revision 2CV102M3.

    As far as I know, all other drivers are up to date, if Device Manager / Samsung website are to be believed...

    Not sure how I can find out what is driving the fans in order to lower some setting or other - there's absolutely nothing in the BIOS I can tinker with on this machine...

    I've been sitting here for 2 hours and fan is constant - pulling the mains gives me about a ten minute reprieve of absolute silence (maintaining only TBird and IE open) before the fan is constant again. o_O
