MacBook Pro Making Strange Ticking Noise

[wjs001]

My Macbook Pro is about 3 years old now. I believe it is the 2011 model. For the past week it has been making a ticking noise. You can hear it here.

I know exactly which area it is coming from but i don't know which part is to blame. All i can say 100% is it is not the Optical Drive, Hard Drive or Fan (Although as you can see from this image it is close to both the drive and the Fan)

Any guidance would be greatly appreciated


Thanks in advance.

Looks like a speaker

Try PRAM reset. Basically hold "P" + "R" + OPT + CMD while starting up. Keep holding and let it chime three times.

Also, does it occur ALL the time? Have you tried creating a new user account and see if it happens when logged into that?

Tried the PRAM reset but haven't tried the user account. Will try now and update. Poiihy, certainly does, and the noise is almost digital so that would explain it a little.

Thanks sooooo much for your help guys. Really means a lot.
