Hi, Ive this used asus MOBO, there is one stain I dont understand. Motherboard runs without any problem but when you remove heatsink near cpu socket you can find this. (pic related) Should I be concerned?

What mobo is it exactly?

Looks like something on the back IO side fried. Not something critical, but it might render some of your back IO ports useless.

Closest ports are HDMI and DP, but it doesnt guarantee that those 2 are affected.
