Question Replacing fried motherboard component via microsoldering

I was messing around with the RGB header on my Gigabyte B550M DS3H motherboard but forgot to power the system down (stupid I know). When I plugged in the 4 pin RGB cable into the "LED_CPU" header, magic smoke came out of the surrounding circuitry and absolutely fried this component.

I'm very new to motherboard repair / micro soldering and have 0 idea what this component is, if anyone could help me identify it and find a replacement that would be very much appreciated.

heres a guide into components of motherboards

now where to exacty source it only the manufacturer would know. as they have the schematics

Perhaps look into a For Parts motherboard listed on Ebay. Then invest in soldering gear but please be wary that you need to perform soldering in a well ventilated area with a fume extractor.

IMHO, you should look into a new motherboard. You're unfamiliar with soldering and that will take time and a very steady hand especially since the area that's affected is in a very tight spot. To add, even if you do end up repairing that one segment of the board, there's a chance that the board might have issues on other areas and will only crop up over time.

Perhaps even reach out to someone like NorthRidgeFix, I follow the channel and they do a thorough repair job. The only thing is, I don't know how much they charge.

Thanks for the welcome! I'll most likely end up picking up a new board since this isn't high quality or anything. Just seems like a bit of a shame to throw it away, since I've already got some of the gear for micro soldering, I'd like to try my hand at saving it.

"they do a thorough repair", i could comment on that part a bit, replaced a microprocessor on a hdd board and it did not work, well it did not work because they left some pins shorted and they left it that way and said it could not be repaired, but i dont want to create a flame, anyway, Lutfij is right, search for a repair center, you have no experience and a motherboard is very very complex, i have 15 years experience with audio electronics, i even create amplifiers from scratch with schematics, pcb (i have a cnc to make the pcb), soldering the components and i would not be able to repair that motherboard(at least i cannot guarantee that is 100% repaired) . You really need someone with experience on MOTHERBOARDS. Or buy a new one.
