The thermal paste moved away from the CPU and settled slightly on the green circuit board beneath it.

The thermal paste may have migrated slightly, affecting nearby components. Check for damage and ensure proper cooling.
I don’t have enough information about the specific CPU model or your cooling solution. If you didn’t use an electrically conductive thermal paste, the CPU is likely fine as long as it’s not overheating.
Yeah, it's fine. Most thermal pastes are not electrically conductive, and I imagine this is by design because they expect people to not be perfect when applying it. Now, I don't want people to be too comfortable with this. If you get it on the pins or the contacts in any shape, then you could end up with a non-functional CPU due to the thermal paste not allowing a proper electrical connection.
High-performance thermal materials like liquid metal are both electrically and thermally conductive. Creating an effective thermal paste without electrical conductivity would be ideal, but most available pastes have some level of conductivity. Non-conductive options exist, though they may not be suitable if applied excessively. Without details on the specific compound used, it's hard to assess risk. For safety, a non-conductive thermal pad is advisable: https://www.amazon.com/dp/B00EZFPOA2?tag...th=1&psc=1
This process is known as "push out" and it's beneficial for a few reasons. 1. sufficient paste has been spread 2. the cooler's clamping pressure causes the material to move outward, showing a secure fit. As mentioned before, this usually means everything is in order. You're unlikely to buy conductive thermal paste unless you notice warnings—it's not that common and often discouraged. If you spot a CPU without push out, consider checking the amount applied or the cooler's clamping force. We hope this assists you!
Your wording about "some" concerning conductive thermal materials stays the same. The main concern is preventing shorts in pins. If this doesn't occur, it shouldn't be a big problem. However, I'm not urging anyone to ignore these precautions.
