--- Comment #16 from Jimi JimiJames.Bove@gmail.com --- Not necessarily. Less fans means less power usage means money saved, and as we can see with my computer, you can keep the card cool without its own fans. I have 4 case fans that are plugged directly into power and so are less competent at knowing when to turn off. Something needs to be done about your fan not activating when it should, though.
