I have a Lenovo R61 Notebook with 1GB Ram and Centrino Duo with 1.80GHZ. I have installed Windows XP and Ubuntu 10.04 on it.
I mainly use Ubuntu on the NB. Everything works fine except the fan. It always runs with very high speed. Running Windows it is calm most of the time. Is there any solution how to regulate the fan speed under Ubuntu? Because this is very annoying. I only use Firefox and the NB sounds like a hurricane. ;-)
