I've been doing some reading, going back through info published in the last 10 years, and got to thinking about the "Myths" or common misconceptions people have about water cooling. I thought it would be interesting to see what the group here thinks are the most common myths/misunderstandings still prevalent today.

I'm thinking about "principles" here, not specific products, so please don't mention brand or vendor names. Thanks - it will be interesting to see what the group thinks.
