How do I get my iMac to shut up?

[qzxyu]

I have the 2011 27" 2.7 i5 and I have quite a small bedroom. When I put it to sleep, it doesn't really sleep. I know this because the internals are making noise all night and when I wake it when I have certain self updating programs running, they are already updated. So I tried logging out, this helped... But I can still hear the computer tinkering around and in such a small room it keeps me up sometimes. I do not want to have to shut it down every night then re-boot everyday. Any way to stop this nonsense?

UN-Check "Wake for network access" in system preferences

Uh turn it off completely?

Agreed. I only leave comps on when the boot up is slow.

That shouldn't be necessary; when sleeping properly it'll be silent.

Tried that, doesn't seem to work. Thanks though.
