Quite funny, as the article starts by saying pump death can cause your water-cooling system to heat up and lead to the obvious cpu death etc, if you are away from the PC. Not quite sure how a visable water-flow meter is going to help you much if again you are not watching it? I'm looking to build a flow meter that gives a relayed output on zero flow...... haven't worked out how yet. You can buy them for around £150 if you are stupidly rich
