The impact varies by pin type; a bent pin might seriously affect CPU speed. However, dust usually shouldn’t be a problem—especially once installed, it’s unlikely to reach the socket.
As long as the pins remain connected while inserting it into the socket, everything should be okay. My 3950x has stayed firmly installed on my x570 Impact board after a CPU change to a 5800x3D—some pins bent a bit, but I straightened them out and didn’t force anything onto a motherboard. It functions perfectly, so avoid removing it unless you want the pins stuck in place later.
Others have mentioned the importance of pin type when considering bending. It could be a ground, voltage, or data pin, among others. The stability of the system might vary based on loads and thermal expansion, though I think a built-in tolerance helps manage height differences so devices can still function even if slightly misaligned.
You're asking about what "dust" means for a CPU. It's likely referring to particles accumulating on the pins inside the processor. If a CPU is stored without protection, dust can build up and block connections between the pins and their sockets. This might affect performance only if it stops proper contact, but usually, as long as the pins stay in touch and dust isn't blocking them, it won't impact the CPU's function. Dust mainly harms cooling efficiency by obstructing airflow and insulating components, leading to overheating and reduced performance.
It means removing the CPU from storage and checking for dust on the connectors. Use a small cotton swab soaked in isopropyl alcohol to wipe away any debris. Done!
