I purchased a refurbished CPU (i7-9700kf) and noticed the connections seem a bit rough.

The used CPU looks questionable, but the rest seems okay. It’s up to you whether to return it.
I possibly cleaned the white residue using isopropyl alcohol; it might affect the pad's conductivity in theory, though it should be okay if it functions properly. If problems arise later, removing it could help with troubleshooting.
Your CPU temperatures are staying within normal ranges after the overclock, but your MOS is consistently high at around 90°C with occasional peaks up to 101°C. That’s a bit concerning—keep an eye on it to ensure stability.
101c sits at the edge of VRM compatibility. A few models handle 110-120°C, but you must confirm with your specific board. Most don’t work well above 90°C. Could you share the board model and its cooling setup?

It doesn't look like a bad board at all. You might want to try undervolting the CPU to improve VRM temperatures. Most 9000 series chips can handle -25mV, though some perform better. Also think about your case's cooling setup—does it allow for strong airflow?
I have three fans installed: two that push air into the front and one that assists the CPU cooler by allowing airflow.
