I recently built a new PC with an AMD Ryzen 9800X3D, but encountered some issues with the motherboard. I found out it was defective after confirming it at a service center. While preparing for an RMA, I noticed I accidentally left a bit of thermal paste on the back of the CPU. I tried to clean it off with cotton pads, but there's still a dark spot that seems to be some residue from the thermal paste. I've also used 70% alcohol to clean it, but that didn't help much. I'm worried if this could be a problem for my future builds. I know thermal paste is non-conductive, but it's on the back of the CPU, and I've heard that sometimes a soft eraser can remove this kind of oil. Is that safe to try? The CPU's backplate looks fine, but I just want to be sure everything is okay.

Sounds like you might be okay! The back of the CPU shouldn't have any direct contact with the motherboard, but it's still good to clean it up as much as possible. If the CPU works fine after you install it in the new motherboard, then it’s likely not an issue. Just make sure you clean off any excess with a gentle touch. And yeah, a soft eraser could help with that residue if you’re careful. Just don't apply too much pressure! Good luck!
The spot you're seeing is probably just a bit of oil from the thermal paste, it shouldn't damage your CPU as long as it's not interfering with the socket pins. Since you mentioned your motherboard wasn't booting properly, it might be unrelated to the paste. If you're worried, using a soft eraser can be a safe way to tackle that residue. Just don't overdo it, and check the CPU pins for any dirt while you’re at it.
