Silent PC Review recently an article about a new technique I've been working on to cool a fanless P4 2.66. There are only two fans in the whole computer and it's working very well so far. Thought it might be of interest around here.
very impressive andinteresting mod, but seems like a lot of effort, esp with the filter that would seemt o cut airflow too much. but i guess you delt with it by sealing everything so theres no easier path, but still, air purifiers use blowers, not fans.
