It is attractive, but as far as I can tell from the product page, and the review they have linked to, the fan control is purely manual. As a user you can adjust the dials to change the speed of various fans, and see the temperature in various parts of your system, but the process is manual.
What I would like is an automatic fan controller that will monitor the temperature, and then automatically adjust fan speeds to keep the temperature within set limits. That way once it is set I can ignore it, save it the knowledge that it will keep my system cool with the minimum of fan noise. Are such fan controllers available?
