I've noticed that two parts of the board get hot really quickly after it's turned on: the main CPU and the LAN/USB controller. Apparently this is acknowledged by other users too, but the common agreement is that it does not heat up so much that it could be harmful to the board - around 50 °C.
Nevertheless, I think it's better to try to reduce the heat on the components somehow, so I was very happy today when we found some aluminium heatsinks at my friend's house that came with his old graphic card.
Since the heatsinks had a film of glue on the bottom already, it was very easy to install them on the board. The heatsinks fit perfectly over the CPU, but are a bit too large for the LAN/USB controller. I didn't want to get messy with metal saws and files so I just hoped nothing gets shorted and attached the heatsinks to both units.

So this mini-project has been a success. It will help to cool the board and probably extend its working life.
