Acer Nitro AN-515-54 Fans issue

Hi everyone,

Recently, I had some issue with my fans : they're spinning at a noisy speed (2000-2500 RPM) even when I do nothing, with a 40-45°C temperature (113°F) for the CPU.
I tried to clean the fans, get rid of the dust, and change the thermal paste for the CPU and the GPU, nothing worked.
I tried to undervolt with Throttle Stop, did not work either.
Even when I try to control the speed with NoteBook FanControl, the fans speed stays around 1900 RPM.

Do you know what could be the problem and how could I solve it ? Thank you very much !

  • This is the temperature table of an515-54:

    The fans will only turn off if the temperature is too low. There's nothing wrong!

    Hi,
    Thank you very much for your quick answer !

    Do you have any advice on how to cool down the CPU then ? Because the fans noise is very annoying, and I'd like them to stop spinning all the time. Or do you know if there's any way to get rid of the table you showed me ?

    Thank you again :smile:
  • If your laptop is under warranty, I don't advise repasting. Now, if your laptop is not under warranty, I advise you to repaste with grizzly kryonaut or artic-mx4. I also advise running undervolting.

    I did the repaste with Artic Mx4, and gained some °C (~ -4°C), I also undervolted (-110 mV), but the issue is still there. Do you have an idea what could make the fans running constantly ?
    (I checked for viruses with Bitdefender)
  • I've seen some reports, that when the user installs two nvme ssds, the fans speed up. Are there two nvme ssds installed on your computer? If so, place a heatsink over the pch to resolve the issue if your laptop is not under warranty.

    Hi,

    Sorry for the late response ! No there are not, I have only the stock SSD installed :/
    I managed to cool down I little more my CPU, now it idles at 36-38°C, but whenever I start a program (browser, Word ...) there is a temp spike at 40-42°C and the fans start to spin. They don't stop even if the temp falls down to 36°C, and I have to use Notebook Fans control to stop them.

    I really wish the BIOS would let me change the parameters ahah.

    Thank you again for your response !
  • What is the version bios?
