Dowsil 340 Heat Sink Compound - Reliable, But Not for High-Performance CPUs
This thermal compound is not ideal for computer CPUs—its thermal conductivity is barely above water at 0.67 W/mK, while even budget CPU pastes range from 1-2 W/mK. However, where it shines is stability. It won’t dry out like other compounds, making it a solid choice for voltage regulators, power transistors, and similar applications where reliability matters more than peak performance. Recommended with that caveat.
