I have noticed significantly lower CPU temperatures on 11.04 as compared to 10.04 on my Dell Studio 15 laptop. And this is a really good thing. So good, that sometimes, my laptop fans completely turn off for a while and then start at a low speed again, before turning off again.
Is this normal?
I am sure it is not a hardware problem or anything because I can feel the base of the laptop and it is really cool (and lm-sensors reports core temperatures at 49 degrees C, I have never seen this go below 50 on the pre-installed Windows 7 actually), but I am not sure if it is normal for the fans to go off once in a while.
Needless to say, this does not happen all the time, only when I am doing something extremely lightweight.
