F17 - problem with overheating

[Paolo De Michele]

hi all,

I've installed F17 on my laptop Sony VPCEB4C4E 32bit (KDE)
I noticed that very hot without doing anything complex; the fan runs like 
crazy -

I opened the laptop to see if there was dust on the cpu fan but it is clean
I noticed that maybe when I watch a video, I look at the mail (thunderbird, 
kmail) or do a bit of multitasking then the fan runs a lot (the cpu never 
reaches 100%)

what can be the problem?
thanks in advance
cheers

In that case, I'd leave the "top" command running in a console, and see
what's reported as using a lot of CPU.

My system usually uses very little of the CPU, but I'll often find that
Firefox suddenly pegs it to the limit if I let some pages run some
JavaScript.  There's plenty of badly coded pages out there.

Also trying a live (linux mint 12 gnome) the fan seems crazy
I only tried to open a web page (firefox) and navigate

We can try to monitor the temperature?
May be a hardware problem in this series of laptop? (the laptop is
equipped born with windows 7 home premium)

No, I was trying to ask if this was a hardware issue or a
software/distribution issue. It appears to me based on what you write
here (using F15/16 with same problem) that the issue transcends F17.
Perhaps there is some HW issue? Trying with a live CD of some other
distribution may perhaps isolate and diagnose the problem?

Usually do not use the laptop in bed but it happens at work, in the
table at home, everywhere.

Honestly I never tried other distributions over fedora (before I was 15
and then 16 but the problem was the same).
You advise me to try another distribution?

Is it actually blowing hot air, or the fans are running hard and blowing
cool air, and something else *says* that it's hot?

Also check the vents.  The air has to go in and out of somewhere, and if
they're blocked, it doesn't cool properly.  My laptop has a rather fine
grille on the outlet, which gets clogged up with fluff.

Also, have you tried it with other Fedora and non-Fedora
distributions/OS/releases? I would first make sure that the problem is
isolated to Fedora 17 and not the hardware, kernel, etc.

Do you have the laptop setting on flat surface so air can get into 
bottom of laptop.
I have seen people have their laptop setting on their bed and it could 
not get any air to the bottom.
