HP Probook 5330M

CORE i3:

Sometimes my notebook feels very hot through the keyboard likes it's burning me. Is this what the temperature should be:

Fedora 14:
[jonathon@hp-cool ~]$

Code:

temp1:        +60.0°C  (crit = +128.0°C)

temp3:        +47.0°C  (crit = +128.0°C)

temp7:         +0.0°C  (crit = +128.0°C)
temp8:         +0.0°C  (crit = +128.0°C)

Core 1:         +53.0°C  (high = +86.0°C, crit = +100.0°C)

now its dropped but it feels hot:

What rpms are responsible for the CPU temperature?

Nothing wrong with the temps...

They are normal. Probably the CPU is located under the keyboard or something. Don't worry.

My notebook idles around 55C with a 2630QM.

Don't worry about it...

This is what they call, a bad notebook design.

Being a i3 and no GPU means it's cheap probably...

Trust me don't worry. Or buy a notebook cooler. That may help slightly

You could check to see if cpu throttling is working on your laptop or not.

Code:

yum install kernel-tools
cpupower -c all frequency-info

Not sure what the output means.

Code:

yum install cpupowerutils

Well, it means that cpu frequency throttling is enabled and working on your computer by having the "ondemand" governor as the current governor. It's also showing you the frequency range and the various "steps" within that range that your cpu cores can run at, and that at the time this snapshot was taken, the cpu cores were running at 1.70GHz, about mid-range between it's range of 800MHz and 2.10GHz.

Another quick way to check what frequency your cpu cores are running at is:

Code:

grep MHz /proc/cpuinfo

With minimal applications running and no heavy cpu processing going on, your cpu should be mostly running at the minimal 800MHz, which would generate the least amount of heat from the cpu.
