[wplug-erie] dual boot laptop over heating

[Seth Keiper]

Also, when you say "customized user-mode kernels," do you mean this user
compiled their own kernel? If so, then look towards a more generic kernel
and see if it helps. Also, make sure where the fan blows out is definitely
clear of any junk. I usually blow out the heatsink and all, this is where I
notice most of the overheating is rooted from. What distro is being used by
chance? There are some distros that have had issues running on Linux.
