    CPU thermal behaviour can change depending on BIOS/Firmware?

    by Contius ·

    Good afternoon guys,

    I’m Marco, I’m new and I come from Italy.
    I’m here to hope to have a clue about my new cpus laptop behavior.
    Recently I bought an Alienware M17 R4 10870H/3080 laptop. I bought it used, but seems to be ok. The fact is that when I try to reset the pc I notice huge heat and a slow pc (imagine for wildly thermal throttling). I noticed that due to temperature were high and no way to use normally the pc. Obiouvsly, bought new from the seller and never repasted.
    So I do it on my own with the new CoolerMaster cryofuze violet, the only decent paste available in the store near my house.
    After a clean and repaste, temperature ( but after at least 3 days from repasting) are very good, in idle stays normally on average 45-48,normal load average 60-65, heavy duty around 80-87 ( here is already quite hot, nearly summer).
    When I talk about average, is the “cpu package”.
    Taking a look in throttle stop, indeed you see the temperature that are quite like ok, but when you bring cores alone and when one or two have a nearly 100% usage, core temperature can spike reaching like 94°c for a second and spikes down to 59, the spikes up 77, spikes down 55, spikes up 88 and down to 65, all of this in a bunch of seconds. This means for me that the real core temperature isn’t so high , but can reach these peaks due to usage. The fans are quite and the laptop is fine cool.
    With the previous laptop that have 10875h, temperature tends stay higher generally but no spikes like these ones.

    Is this can be caused by a thick layer of thermal paste ( also is a very dense one, takes three days for settle)??
    It can be caused maybe by a past use in continue thermal throttling reaching high temperature (it may be damaged?)?
    It can be caused by a simply different firmware/bios that make behave cpu different of the previous one?

    Finally, is this behavior normal for a cpu?

    Thank you for have read my message, give you my

    Best Regards
