How can I lower the CPU temperature?
My experience with Linux on laptops is that it will run hotter and have less battery life than the OS it came with :( I use Ubuntu exclusively on my desktop but I probably won't try again on the laptop for a long time.
To answer the question: if you want to lower the CPU temperature, you can underclock the processor. This will make your computer slower, though. This guide might be helpful.

I have installed Ubuntu 12.04 on my EeePC 1015PX and I've noticed that the CPU temperature does not go below 60ºC (70 is usual). Looking at powertop it seems the 2 cores (Atom N570) are idle most of the time. I've installed jupiter (w/ jupiter-eee-support) but it did not help.
Edit: Meanwhile I've found out that
echo 2 > /sys/devices/platform/eeepc-wmi/cpufv
is supposed to turn on Super Hybrid Engine. Though it seems to help a bit (temperature goes down 2-3ºC), the temperatures are still in the 60-70ºc range.-
