Can RAM RGB cause coil whine?

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

Things I need help with:


none atm


I hate Intel's pricing, Ryzen's weird quirks, Nvidia's pricing, and Radeon GPUs in general




Products I like:


Sony Xperia Z1 / Z2 / 10 ii, Asus Strix 970 / 1070, Samsung SSD, WD HDD, Corsair PSUs (AX, RM, CX(grey)), GeForce GPU, NZXT N450/S340, be quiet! Coolers, G.Skill Trident RAM, Logitech M525, Logitech G440, Razer Deathadder Elite


Products I hate:


Xperia Z3, XiaoMi 5c, Radeon GPUs, Razer Audio Products, any bloatwares


Companies I absolutely adore: (and hope it stays that way)


be quiet! - sent me AM4 mounting for my DRP3 even though it's way past the timeframe stated, no questions asked

Corsair - very good RMA experience, absolutely recommend


Companies I hate:


Nvidia, Intel, Apple, TMT (Thundermatch, a retailer)


Personal Blacklisted Companies:


Acer: shit tier quality products, shit tier customer service thus far, they "tried" to solve my issue but they arent really doing anything but delaying and delaying. (on-going case since July)

Gigabyte: horrible customer service (gigabyte had literally 0 customer service, asked me to go to retailer with NO WAY to email them about a question) but at least they fixed my shit in ONE MONTH (would probably take me 1 hour to fix if they let me email them)

XiaoMi Phones: built like a tank but the software is buggy as all hell

Seagate HDD: had too many dead seagate drives

Kingston SSD: 300V controller swap thingy

Razer (except their mouse)


Remember, just because I had good/bad experiences with these companies/product, doesn't mean you will have similar experiences too. I would still recommend these products if they made sense for your needs, but I'll add a disclaimer of my experience if it's relevant. Feel free to DM me asking why they are where they are.
