Hey there!

I'm using a Cooler Master Stormstryker and I installed two Rosewill 120mm fan's at the bottom that have white LEDs. I've plugged them into the case fan controller and when I lower the fan speed using the controller my bedroom turns into a disco. I did a search and http://www.tomshardware.com/answers/id-1840681/safe-plu... here it was noted that when doing this fan LEDs may 'dim' which I actually wouldn't mind at all but the blinking is pretty annoying.

Part of the issue is that the frontal fans that are came with the case (and also have white LEDs) have two cables... one for the fan and one for the LED (this allows the LEDs to be turned off via button on the case), Then the controller comes with one additional LED cable and two additional fan plugs. Of course, the fans I've purchased only have 1 cable.

Is there anything I can do to remedy this while still having all four controlled by the case?

Sounds like the controller isn't outputting enough voltage to the fans LEDs when turned down. I would think about upgrading the fan controller and the case fans. Stock case fans and fan controllers tend to be crap anyways.
