This is a shot of the innards of my PC from a couple years ago, the Vega 56 featured in this shot has since been upgraded to an RX 6600, and the CPU I was using at the time, an R7 1700, has since been side-graded to an R5 4500, and the Wraith Spire box heatsink that’s featured in this shot has since been upgraded to an NH-U12S redux /w the second fan kit, admittedly an overkill heatsink for an R5 4500, but it does a really good job keeping that CPU cool.
Still can, RGB is at a minimum in my PC, the only RGB currently at play is some pulsing lights on the mainboard which I choose to ignore as it’s not hurting anything.
I would imagine you could turn even those off, if it bothered you enough
I could, there’s an option in the BIOS settings, I just don’t because my mainboard’s RGB is so low-key that it doesn’t really matter if I leave it on or not, and its default setting is to pulsate.
