I'm having problems with my G62 overheating after about 10 minutes of normal usage. I'm certain it's not a hardware problem, because I have tested Windows 7 (I know it's a sin), and it behaves normally; I can even hold my laptop on cloth.

the first quiestion to be asked is if you did follow the wiki:

Yep, installed Cpufreq-utils and laptop-mode then I've set up the modules and daemons in /etc/rc.conf, both CPUs to run at 800mhz (ondemand gov.)

Maybe I'm a bit too late but it's your discrete graphics that's causing the problem. The radeon drivers have very bad power management.
I fixed the issue by disabling it and using the intel only.
Make sure you have xf86-video-ati installed.
add these two lines to /etc/rc.local :
mount -t debugfs none /sys/kernel/debug
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch

maybe the following options to the kernel will help

nomodeset pcie_aspm=force i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 vga=773
