iMac making a buzzing, humming noise from the back

My iMac has just started making a buzzing/clicking/humming noise from the back. Its not loud, just annoying and constant, its not over heating and it doesn't sound like the fan. Nothing I try helps, is there anything suggestions as to what I could try, something that doesnt involve taking the Mac apart would help greatly. Or is it time for an upgrade?

The first thing to do is back up your hard drive as soon as possible.

You don't give any info about your iMac but I would suspect that your hard drive is about to die.

Easy to replace on a 27" iMac a bit more difficult, but possible, on 21.5" iMac unless it is very old.

Thanks I thought maybe that would be the case. Just backed up everything and the noise is still humming. It’s old now 2011, 21.5 so maybe time to take the plunge. I wouldn’t want to change the hard drive myself.

It's not worth paying to try and ugrade your existing mac - plunge!!

Thank you both.

Definitely time, I have tried troubleshooting a few ideas but sound is still continuing and it’s on and off now.

Try booting from an external drive which will stop the installed drive from kicking in and if the noise stops then you know its the installed drive

have a look on here for further help

Thanks all so bought a new IMac and just trying to wipe everything off the hard drive. Is it worth in your opinions to replace hd to sell it or sell as faulty? Any suggestions appreciated

I’m sure you’ve posted already but what age is it again.

Just reread the post and can see it’s a 2011 so may not be worth fixing. If it’s just the fan then you might be lucky and see if a local repairer will replace the fan or do a free assessment and give you a price to repair. If you were to send it to us it would be a little dear due to the shipping costs but a fan replacement would only be around £75 locally I would imagine. - hope this helps but if you’re interested in my services you can find out more at our website - click here sure if the links aloud so it may be removed. Best regards Gary

Just another note. If it’s coming and going I doubt it’s the hard drive so probably is the fan.
