Led's in SysFan 3

post #1 of 4
Thread Starter 
Hello,
I have MSI z77-g43 MoBo. I installed Leds and instead putting them throw PSU i put them in Sys Fan port on the mobo, i thought i could control the Brightness of leds by decreasing or increasing the fan speed in present , but in BIOS i dodnt see SysFan 3 ,

Is any way i can control them ?

unless they have a pwm header, or you are using them off a controller probably not. would be cool though.

what about a different header?

I am sorry but i am only 1 year in canada and i dont anderstand what you mean "header"
post #4 of 4
The port you referred to on the motherboard is a header. Generally headers are male connections available on the mother board (meaning they have the pins that insert into a connector). What I would suggest is like he said getting a PWM header (connector) so that it potentially shows up as a fan OR you can do as I and many others have and install something to manually dim the lights. I added a cheap DC voltage dimmer, 7-12V range, and ran my power into one side and the light connections (+ and -) into the other side and have a dimmer switch that I can use to manually adjust the brightness. This is just a suggestion since I'm not sure how well you can control, if at all, lights with the motherboard PWM fan header.

Curious note, is the header (or port) a 3-pin or 4-pin header. If it is 3-pin then you won't be able to control it. It will just be full power all the time.
