JLJ Thermal Paste 4g Advanced Carbon Compound for CPU

Bottom line: The JLJ Thermal Paste 4g Advanced Carbon Compound for CPU ($8.88 on Amazon as of 2026-10-06): Non-conductive carbon compound, no metal particles to short a socket or GPU VRM; main trade-off: no W/mK conductivity figure published, so it cannot be benchmarked against known pastes.
