ticking or clicking sound

[greythorne]

hello there,

late 2009 mac mini 2.53GHz/4gig ram/320gig hd

ok the issue is that I'm constantly hearing the ticking or clicking sound from my mac mini. Could any tell me what could be making those sound?

Thanks oh is it a cause for concern or should i completely ignore or changing hd would solve this annoying issue?

It's probably coming from the hard drive. I suggest you to take it to the nearest Apple Store and let them fix it
