X220 running HOT -- should i worry ?

[rzl]

Hi people!

My x220 has been getting hotter and hotter in the last days.

I'm not the kind of person that actually shuts down the computer, i just leave it in stand by on the desk or shut it down to suspend-to-ram and this never gave me a problem.

I began noticing this problem since i switched from Debian Wheezy (who used to randomly freeze) to Ubuntu 12.04.1 LTS (3.5.0-36 kernel).

Any hints/ideas ? Should i open the laptop and clean it from dust?

Thanks in advance,
Rzl

Believe it or not, my X220 runs hot in summer too.

The room temperature heavily affects the CPU temperature. By switching to Ubuntu I presume you did a clean install. You might want to instal TLP to activate all power saving features. (pretty much like installing the chipset drivers under Windows)

Mine has had some issues after suspend but overall runs ok (i7 version here)..

I would try to understand the distro you are running; i personally hate Ubuntu, the people who tend to use it are windows/os10 expats and tend to know nothing in regards to whats under the hood.
