Why do you folks say over-heating? Is it too hot to touch? Crashing?
I noticed mine got quite warm when some buggy daemon was stuck thrashing the CPU. Fortunately I noticed the heat before the battery was completely drained.

The main heaters in your phone:
- 3G transmitter
- GPU
- WiFI transmitter
- Battery
Try playing bounce, torrenting over your 3G, running a local hotspot with joikuspot and charging the N900 at the same time...
As previous posts have mentioned, this is expected, however i guess that doesn't mean its a good thing! Am concerned this could do some damage, particularly if n900 doesn't have the same mechanisms to deal with this kind of heat as you would expect to find in a regular computer.
Does anyone have any experience of this behaviour or can comment on the likelihood of some damage being caused by overheating in general?
Cheers,
Adrian

So what can we do to modify our N900s to vent more heat?
I was thinking of drilling or cutting holes in the battery cover.
I was also thinking of using thermal paste or phase change tape where the motherboard affixed heat sinks touch the main case. I don't have the link handy, but there's a nice n900 disassembly video by techseven on youtube.

I've also read of (anecdotal) reports that 3G\WiFi transmitters\receivers being (permanently) affected; causing them to have less sensitivity and shorter ranges. But, I don't think that's as conclusive as the battery issues.
Other components have much higher temperature tolerance and general durability, I think.

I got a new n900 when my previous usb port came out, I usually put my phone under my pillow and when I got it in morning it was really really hot, even while im typing this from the n900 its still really hot.

You dont get enough radiation during the day?
Back you your question did u overclocked it? is brightness set too high? Any CPU intensive apps in the background?
