Addendum: more than a few times the laptop has actually shut down due to
overheating, even while not running on overddrive (just Epiphany with
YouTube, Gmail, FB, Eclipse and some non-intensive stuff running). This
sort of clues at least me to believe it might be VGA-related (it the fans
normally go into overdrive when Youtube is up).

I am running an HP Probook 4510s if anyone else has had similar issues.
