    Arrow Fan question..

    Oh thanks for all that information..
    I have one more question also.....Can you control the fan speed with your motherboard or not?..
    I have a gigabyte AM3+ motherboard right now, but the default gigabyte BIOS/UEFI/ACPI thing that controls the fan speed always seems to run the CPU fan way faster than it needs to be....so I usually use fancontrol (or maybe I could use thinkfan also?) to make linux control the fan..

    I am wanting to buy a gigabyte FM2+ motherboard and an APU soon, but I am wondering....am I going to be able to control the fan speed?.. I don't want to sit there all day with a loud fan noise going constantly..that will drive me crazy..

    I have a Kaveri APU and fan speed was not a problem until now. The only time I heard the fan was when I entered the UEFI setup and let it sit there for ~half an hour, this makes the APU heat up like crazy. During normal operation under Linux the only noises I hear from the case are caused by the HDD/optical unit. This might change during the summer when the ambient temperature will rise, but I don't think it's an option to let the APU fry just so it's silent. I'd rather switch it to a lower TDP.

    No issues with that and thus never needed it. As i said , i had both the 85x and 88x board versions - one with A8-5500, the other with A8-6500. None gave me any fan speed related issues. It seems the fan speed regulation is done by the BIOS, has nothing to do with lm-sensors (the ITE monitoring chip supplies the info to the BIOS and while its nice to see its output, its not required for throttling). You can see this in the BIOS/UEFI, where you do get dynamic fan speed throttling.
    I have the computer on the table, case open (i often plug hdds for dd or various recovery/backup purposes) and the fans (one STOCK APU cooler and another case fan) around 40-50 cm from my face and barely hear it. If the CPU is under load, i can hear it spin up and down, in fact i can assess the load just by hearing it (the fan speed is perfectly in sync with the load/temp increase/decrease), but its not very loud in any case.
    BTW i use the STOCK fan - you will see why i capitalized it if you see an AMD APU stock fan (its probably the smallest fan in existence for regular desktop CPUs).
    Another thing is that both APUs i had are the 65w variants - and they dont seem to have any overheating issues (even with the above mentioned abysmally small stock cooler).
    But i dont know what happens with the unlocked 100w models, i heard that those tend to heat up more.

    @Ansla:

    In the BIOS/UEFI there is no mechanism to scale the CPU/GPU speed down dynamically, you have it running full speed constantly, its normal to heat up to a certain temperature (50, maybe 60c with crappy default coolers). But higher (more than 60, 70 etc) indicates that it has inadequate cooling.
    If you load all cores under the OS, it will heat up just the same while under load, only it will cool back down when it gets the chance. Additionally to the CPU, the OS will scale the integrated GPU speed too, lowering a few more degrees.

    Or just switch to a better after market cooler and low noise fans.

    You can even go fanless with the A10-7950K if you have a nice airy case using this beast http://www.quietpc.com/nof-cr-100a

    Default lm-sensors

Now if the XM uses the same chip, its a problem since the lm-sensors guys stated that ITE stopped sharing diagrams with them and thus new ITE chips ( are unlikely to be supported. I sent a mail to the kernel developer in charge of the it87 module and he said he didnt even hear about this chip model.
    Previously i had a F2A85X-D3H mobo that has a supported ITE 87xx monitoring chip and i supposed this one will use that too but it seems i was mistaken....

    But anyway, the mobo works fine, i have it for a few months now and had no issues with it (i have a A8-6500 APU with it). Thermal monitoring is still possible for both the CPU and IGP, but the reportred values from the k10temp (CPU) and radeon (GPU) drivers are not real ones especially when idle - instead they are used internally for thermal throttling and they approach real values when the chip is under load for some time (for example i have 3-5C reported when idle).
    I also have a F2A88X-D3H MB and I've found that lm-sensors can be made to work if you force the it87 driver to load:

    modprobe it87 force_id=0x8728

    i.e. make it think it's the IT8728 chip instead of the IT8620. This gives a range of sensors with sensible looking values for temperatures, fan speeds and so on. This was on CentOS 6.5 (kernel 2.6.32-431.5.1) with the elrepo kmod-it87 driver.

    Wow. That actually works!!

    Nice one.

    BTW the output looks exactly like that from the 85X board that has a supported IT87 chip so it really works.
    I have a self-compiled kernel from git, i use Debian Testing 64 bit.
