    Nah, I'm still looking at the ACPI spec. The thing I'm wary of is creating ACPI objects that don't exist. For example, to set any active cooling temperatures you *must* define a fan object and that doesn't exist in the current Toshiba ACPI DSDT table.

    Couple questions for you:
    1. Out of curiosity, would you prefer an active (turn fan on) or a passive (throttle CPU) cooling preference?

    2. BTW you have a P100 with discrete graphics (NVIDIA or ATI) right? If so, exactly which model do you have (you can use GPU-Z to get the details quickly).

    3. Also is the fan that keeps whirring up the side vent or the rear one? I'm just trying to see if we're looking to control the correct fan.

    Hi.

    okay no worries.

    1. active turn fan on
    2. No its one where the GPU is on the chipset and its an onboard Intel GM945
    3. Only has one fan cooling both CPU and GPU and vents air through the rear centre outlet.

    Been playing around with the Notebook Hardware Control Program from that forum you posted and the latest 2.4.3 lets you create an ACPI profile but you need the full program to do it

    Hi

    tried the BIOS worked fine no problems apart from the fan still whirring loudly for a few seconds then drop back to normal speed.

    Can you get something to monitor the CPU temperature and see if it's at 55C+ when the fan kicks on? Unfortunately there's no fan control in the BIOS, so it just kicks on full power right now. I just want to see if my _AC0 is working or not.

    (OP)
    Its difficult to determine as at idle its hovering around 50c and without an RPM counter. Using Coretemp for the CPU temps.

    However after several runs I can tell you if I use Prime to load out the CPU cores the fan comes ON at 60c and if I stop stress testing the CPU the fan goes OFF at 55c. Tested this several times. So looks like its working.

    Cool...let me know what you want to try next. Perhaps add a _AC1 (low power fan) at around 60C and also raise _AC0 (full power fan) to something a little higher...maybe 70C?

    I'll need some guidance from you based on your stress testing.

    Hi

    could you add the _AC1 as you said but is it possible to raise _AC0 full power fan to 65c ? If not 70c is fine.

    try 55c for _AC1.

    Test 2.

    Laptop seems to be running cooler it hovers between 44c and 50c when idle and annoying 2 second burst of fan does not occur.

    However if I stress it as soon as temp hits 55c the loud 2 second burst of fan occurs. The temp when using the laptop for say browsing the internet or getting email hovers around 50c to 60c so as the temp variation goes up and down through that range when it hits 55c the loud 2 second whirring occurs more frequently possibly because it keeps breaking the 55c barrier. Now its idling currently at 43c and no annoying fan noise.

    Yeah definitely now everytime the highest core CPU temp hits 55c you get the loud annoying burst of fan speed. 56c and above its fine. So question is whats causing the fan to hit that annoying speed at 55c.

    sounds good to me.

    Its been on all day and still the fan bursts at 55c so its definitely hitting that temp that causes the fan burst.
