I have a TTGI 470W PSU from Directron, which had 3 fans connected to a little "hi-med-low" controller on the back. Well, the controller broke, I RMAed, then it broke again, so I just replaced the fans with the slim version of the L1A. They are running at 5v and are connected to a molex, not that silly controller. Dead silent. I am not having any problems associated with PSU overheating, so I am rather satisfied... glad I didn't do something silly like WCing it.
