Coolermaster Jetflo fan conundrum

Hardware Hub Cooling

My build is a month old now and has been great except for one tiny nagging problem I cant seem to work out, one of my Jetflo LED fans mounted in the front of my N200 is a different colour blue to the other. One is a dark ultramarine type blue and the other is a much lighter blue closer to Cyan.

Here is the kicker:

  • I have changed the fans around by swapping it with the exhaust fan. The problem persists. 
  • I have run them with and without the low noise adapters that come with the fans. The problem persists.
  • They are all running at the same RPM or to within 20-50rpm of each other as registered in the BIOS. The problem persists.
  • All the fans are running on individual PWM headers (they are PWM fans) on my Mobo and all are set to the same mode (Silent) in the BIOS. The problem still persists.

What. The. Hell.

uh, you mean the color of the led's dont change if you configure them differently?

 

maybe your eyes see different colors and it's just the angle you are looking at them.

One of the fans will be a different colour when run from a certain header on my Mobo, but the BIOS is telling me I have the same performance as the others so it must be receiving the same amount of power. 

Doesn't matter which angle I look at them from.

get a multi meter and test those headers.
