    My 2011 macbook air which I've owned from new has started chirping/squealing whilst loading websites - mainly ones which are graphics intensive. Really annoying!

    Presume this is the GPU ? Can anything be done and is it something to be concerned about ?

    Thanks.

    chirping/squealing noises? I bet it might be coming from your fan not your GPU....

    Most likely "coil whine" from one of the switching supplies. Basically, the windings in one of the coils has gotten a little loose, and you hear it sort of like a speaker when under heavy load. Sometimes a capacitor will be the culprit (acting like an electrostatic speaker). Not likely to be a problem with the GPU unless you're also seeing visual artifacts.

    Most likely a worn fan dude. Run something intensive, like encoding a video, and disable display monitoring then u would know.

    Easy to tell coil whine from fan noise: fans ramp up and down slowly.

    It's not the fan - that runs fine.

    It's a high pitch noise, occasional chirp - must be a GPU coil/cap. I'll have to save up for an upgrade!
