Can RAM RGB cause coil whine?

[Cj-Puerto]

Hello to all LTT forum users. 

Some days ago i made a post asking about a high pitched noise that was going on in my computer thinking something was wrong with it.

 

Original post: 

 

After some nice people confirmed that it was nothing to be worried about, i didn't pay much atention to it. 

However, the noise was getting really (REALLY) annoying so i did some diggin arround online, settling in that it was most certainly coil whine. I read in some forums that people were having this issue in Gigabyte motherboards when having the RAM Rgb turned on, so i decided to give it a shot and turn it off with RGBFusion 2.0. 

 

Guess what, it actually WORKED and turning it off reduced drastically what i think is coil whine comming from the motherboard. 

 

This got me really curious on why this is happening.

 

Does anybody has an idea on why this is happening?

 

Thank you in advance, best regards.

probably the RGB's PWM signal causing the whine in the power delivery for it

Huh, intresting. Do you think theres a way to have the RGB on without that annoying coil whine?

 

Thank you for your reply.
