    Dell Inspiron 24 5459 AIO making humming noise

    For the past few days, my Dell Inspiron 24 5459 AIO has been making this loud humming noise and I'm not sure why. What can I do to diagnose this problem and hopefully correct it?

    Hard to tell or diagnose without being able to hear it.

    Have you checked the external power supply?

    Here is the link to the Dell on-line diagnostics.

    Upon running Diagnostics (F12), it appears the CPU fan isnít responding correctly.

    It might be only a small accumulation of dust on the fan blades, causing it to be out of balance. If you have the knowledge, open it up and brush each blade carefully with a small art brush

    When mine started making these type of noises I opened the case and a rug fell out lol.

    Cleared the rug, cleaned the fan blades and was silent again.

    Always best to renew the thermal paste also while ya there

    The PDF service manuals are here
    Does not look too difficult to do the job yourself, clean the fan or replace it.
    It looks to be a Laptop board in a monitor type of thing.
    YouTube is a good source of disassembly guides to similar models.
    Whilst you are cleaning the fan note the model numbers on it so you can find a replacement fan, if required.

    Here is the link to the manual on the US Dell site, since you are in the US. Same manual as the English site.
