One of the things I do with the iMac is play WoW, and the display on the
21" screen is awesome after my old 17" G5.

However, the top right corner of the casing gets very hot after about an
hours play, to the point that it's uncomfortable to rest my hand there.

Can someone advise me:
1. Is this something to worry about and if so, what should I do
about it?
2. I do see references to fan controllers to reduce the
operating temperature by incrasing the fan speed. Is this the way
forward?
3. Is it worthwhile, in the light of the temperature problem to
buy the advanced warranty from Apple when the 12 month warranty is due
to expire?

This is very common (or was) in the laptops, although of course people
notice it there, whereas not that many are going to be fondling their
iMacs.

I have an ancient 663 TiBook that gets very hot- feels like 55-60C. It
seems to be the graphic processor that does it. Probably the same for
your iMac. The TiBook is seven years old and still working fine- as in
'fine but really needs a new battery'.

That kind of temperature should be just comfy for ICs.

Have you got iStat Pro? It's free, and would give you more specific info
on temperatures etc.

Why would you try resting your hand on the top right corner of the casing?

Games do tend to make the machines hot. Have you measured the
temperatures using (eg) iStat, or Hardware Monitor from bresink.de?

Personally I wouldn't worry about it, but maybe the temperatures are
really high?

The machine may automatically increase the fans to compensate and cool
it down if it needs to. But if that's happening too slowly for you, you
can install the free smcFanControl menu doodad to gee them up a bit.

Dunno. Actually my MBP's going to be a year old soonish, and I need to
decide whether the 2yr warrantee from John Lewis is good enough for me,
or if I want to buy AppleCare.

I've tended to get the extended warrantee on laptops, but not on desktops or
towers. So far this hasn't come back to bite me, but there's always a first
time.

Yes, I have. I'll run WoW and note the temp figures and post them
here.
