    I think you have unrealistic expectations.
    This unit has 4th gen 2 core CPU rated at 35W TDP. [1] Which is not
    as efficient as modern CPUs and don't have the ability to step-down
    to low-frequency (under 1GHz) modes.
    Turbo Boost doesn't count in the TDP rating and it makes this
    mini-PC to generate even more heat.
    That amount of heat has to be dissipated with super small heatsink
    and cooling fan. [2]
    Keep in mind, that fan also has to cool down every other part of
    this mini-PC, like ICH, RAM, HDD and power circuit components.
    No wonder it struggles to keep up and produce so much noise.
    Put this mini-PC under any, not just Firefox, multi-threaded
    workload and you will have the same outcome.
