If anyone has any info about this system, if or > suggestions on why I should or should not buy this creasy thing, I'd be interested in reading your comments off list. Here's a couple of things to help narrow it down. 1.) Does the fan operate as designed while using the laptop ? 2.)Or does the fan only come on with the power off ? If you answer yes to the first one, it may be a simple calibration error with the temp. monitor circuit. If you answer yes to the second, I would suspect a bad connection. If the fan is always on then you may have a shorted thermistor. In any case, if you haven't bought it yet, send it back. -yui shin Visit our website regularly for FAQs, articles, how-to's, tech tips and much more http://nospin.com - http://nospin.org
