    I just got my x86 in the mail yesterday and I was a bit surprised to see how hot it gets (it idles at around 70 c).

    so my main question is if this normal?
    Do I need get a fan for the heatsink?

    What OS are you running on it? It's possible that the power profile is set to high performance and never letting it clock down or turn off cores not in use.... Check and make sure it's set to balanced or something like that. Or, yeah, get a fan if you aren't comfortable with the temps... Never hurts.

    It's a passive cooling so depending on the work load, that can be a factor on the temp. The temperature of the room can also be a factor as well.

    According to manual, heatsink temperature must never go above 60 C.

    Quote from manual: "Temperatures indicated are the maximum temperature that the
    heatspreader / heatsink can reach in any of its parts. This means that it is
    customer ’ s responsibility to use any passive cooling solution along with an
    application-dependent cooling system, capable to ensure that the
    heatspreader / heatsink temperature remains in the range above indicated."

    I've recorded 87°C core temp today, as delivered and in free air.
    A fan should really have been delivered standard, the board as it is can not be used at its published specs.

    That's just BS, why supply a heatsink at all then if it's not suitable anyway.

    I agree, the on board heat sink seems to be wholly inadequate for 6W TDP. Intel are quoting 6W at Base Frequency (not Burst):

    "Thermal Design Power (TDP) represents the average power, in watts, the processor dissipates when operating at Base Frequency with all cores active under an Intel-defined, high-complexity workload."

    To the best of my knowledge, the manual refers to the heatsink when it specifies the temperature limit, not to the core processor.
    You measured the temperature of the processor, did you?
    I wanted to reasurre you anyway that we have made tests in a climatic chamber.

    Manual refers to any part of heatsink, including parts which touch processor - so this means that surface temperature of processor must not ever reach 60 C, according to manual.

    Yup, but it looks like at full CPU load the temp difference between CPU and heatsink is < 10°C.

    The CPU starts throttling once a core hits 86°C (when there is no GPU use).
