laptop meltdown

[stevew]

The RWBL super laptop has always run hot. Well the last few weeks it has been periodically shutting off. I install a program to measure the temp and its nearly 70degrees centigrade. I figure the fans are clogged so I blow them out. Still doesn't help. The next step is to take it apart right? Its probably just pet hair.
Do I need a cooling stand?
