Re: How can I make my computer run cooler?

Before looking at exotic solutions, have a think about airflow. Many 
people (including some manufacturers!) think that just bunging a fan or 
two in the case will solve heating problems, but it is important to 
consider exactly where the air is going - a little care in routing cables, 
positioning baffles etc. to duct the air where it is needed can vastly 
improve things. Take care to avoid unwanted air loss through unused slots 
or connector cut-outs.
