Very cool compared to desktop/laptop ones... That's what makes ARM superior in the mobile world.

how cool cpu of our N900 (and others mobile devices like it) without a fan?

it is all about the area, and area of heatsinks outer core when being more specific. and there are several limiting factors such as air gap (heatsink flanges cannot be microscopic because certain air gap must be reached in order to archieve the best possible heat transfer etc etc etc)
and it of course depends fully on heat dispatch of a processor. more mobile processor = less heat dispatch.

Also ARM is a very low power CPU (electrical power not processing power), one of the the most efficient processors around IIRC
ARM processors are low voltage, ultra low voltage etc., all designed to keep power and therefore heat down.
Think of the ARM CPU as an energy saving lightbulb, its a bit like a 15W bulb that's equivalent to a standard 100W lightbulb.
