Hi Orin,
This is how I did it.
I'm talking about the full size Apple thin keyboard, not a laptop.
Go to system preferences.
Click the Displays button.
Using VO Right Arrow, under the display tab you will see as one of the
items, at the end of the list is brightness.
Just before you get to the Brightness label, you will find the
Slider's Value, probably 100, Just slide this control to 0 or
something much lower than 100.
Then exit system preferences.
HTH.

How do I lower the brightness?

Hello Orin and Esther,I have an iMac that's about 2 months old.
it's the 24 inch with 2.8 processor.
I was having some fan noise and apple replaced the fans yesterday.
The technician said that the unit has 3 fans. 1 for the CPU,
another for the Screen and he didn't say what the last one was for,
but I'd say probably the power supply. He said these machines get
rather warm. He said that the problems on earlier machines, say
2006 have been corrected.
This is something I've done. By default, out of the box, the
brightness is set to 100 percent. I lower mine. In fact I lowered
it to 0 on one machine and both my wife and son said that the
screen is still clearly readable without any problems. So we've set
the brightness on 3 iMac machines between 0 and 50 percent. In all
cases, the machines run much cooler.
Just my families experiences with this heating problem.

Hi Orin,
I heard about overheating problems in the first generation of
iMacs, and
there are many articles that appeared in 2005 reporting on this
problem.
You can try downloading a freeware tool called Temperature Monitor
that people used for diagnosis and use it to provide data, either by
exporting file contents to a file and/or by taking a screen snapshot
that you could send along as an attachment if you are in email
contact
with AppleCare or other service. You shouldn't have really high
temperatures. Your iMac is only a few months old, and shouldn't
have any problems. If there is nothing blocking your fans, etc. I
would
get in touch with your local Apple Store. You'll still be under the
warranty period of 1 year. Incidentally, I know this subject has
come
up on the list before, but it's a really good idea to get AppleCare.
That's especially true if you don't live near an Apple Store and
need
extensive phone support after the first 90 days.
Here's the web page for Temperature Monitor:

There are links for the download, online manual, and notes.
Good luck.
Cheers,
Esther

Hey all,
Just wondering, although my iMac is very quiet I really can't
hear it,
it's getting utterally hot, should it? I mean, this is a desktop,
and
I keep it on, and I just don't want it to melt away. Shouldn't this
thing have a fan in it to keep it cool?
I'm currently listening to 06. Soldiers Of The Wasteland by
DragonForce on the album Sonic Firestorm and is currently Paused.
