The thermal paste cannot harm the pins of an AM4 CPU.
Hi there, unfortunately some thermal paste has stuck to a few pins of my AM4 CPU. I attempted to clean it with spiritus (alcohol), but it didn’t fully remove all the residue. The tips of the pins and the upper part are clear, but at the tiny solder joints where the pins attach to the CPU, there’s a thin layer of thermal compound. The main concern is whether this compound could harm the CPU. Thank you!
Most thermal compounds aren't conductive, and conductive ones would be worse—liquid metal would be even more problematic. A thin layer of paste might not be ideal, especially if it forms a thick barrier. From what I found online, Arctic Silver 5 is meant for heat transfer, not electricity, though it can have slight capacitive properties that might cause issues if it connects nearby circuits. It seems luck plays a role in avoiding problems.
Most thermal paste is designed to conduct heat well but offers limited electrical conductivity. If it lacks electrical conductivity, placing it on pins may create resistance between the pin and socket or prevent proper contact. Conversely, if it conducts electricity, its resistance can be higher than direct gold-plated copper connections, potentially leading to issues. The recommended fix is to gently clean the pins using a brush or isopropyl alcohol, ensuring they are free of debris before use.
