When running Vista I undervolt the CPU using Rightmark CPU Clock Utility. That way the max core temp. is 60-65 degrees Celcius (140-149F). Without Rightmark max temperature is close to 100C (212F).

Ideas on how to undervolt in linux?

When I’m not using wireless (ex: I’m on a train/plane), I unload my wireless module as well. My boyfriend unloads his ethernet module, but I usually forget to do this.

For me, those would be:
# modprobe -r btusb iwlagn sky2

If it has to be quiet and I don’t have headphones, well, no point in having sound drivers, is there?
# alsa force-unload
Though warning, this will kill all running sound apps (including any volume mixer applets you have on your panel).

You can load modules again when you’re done with:
# modprobe
Giving it a list of modules where it says .

Warning: If you use the K option (disable polling CD ROM drive), you will need to manually mount your CDs with:
sudo mount -t iso9660 /dev/cdrom /media/cdrom
or something close to that (check your mountpoint and device nodes).

Note that “#” means at a root prompt. Ubuntu users, that means “use sudo”.

If you want to see what modules are in use, the “lsmod” command will tell you. Here are common things you can look for:
WiFi:
Intel: lsmod | grep “iwl\|ipw”
Atheros: lsmod | grep “ath\|madwifi”
Prism or Orinoco chipsets: lsmod | grep “orinoco\|hostap\|wlan”
Broadcom: lsmod | grep “^b*43*”
Realtek or Ralink chipsets: lsmod | grep “^rt”
Audio:
lsmod | grep “^snd”
Ethernet:
sky2 is one of the most common for laptops
