Why does CPU run fast when running Linux?

Postby UlsterScot » Tue Jan 22, 2013 3:09 pm

I just installed Linux Mint on my computer in a dual-boot with Windows 8. Why does the CPU & fan run fast while running Linux? When I boot into Windows 8, it calms right down... :roll:

I don't think anyone (at least not me..) can understand the question, what does fast mean!

I think he's talking about his CPU cooling fan speed.
If so check your BIOS first. Make sure its up to date.

Also, post your hardware specs here as well.

Also try to install Sensors Applet:

Code: Select all

sudo  apt-get install sensors-applet

Is it already installed?
The try (answer yes to everythiing)...

Code: Select all

sudo sensors-detect


Then edit grub
sudo vit /etc/default/grub
or
sudo nano /etc/default/grub

Add this

Code: Select all

 "acpi_osi=Linux"
to the end of GRUB_CMDLINE_LINUX_DEFAULT =
Will look something like:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash acpi_osi=Linux”

then restart
