Review on Arctic Silver High-Density Polysynthetic Silver Thermal Cooling Compound with Bonus Tool - 3.5g for Optimal Performance by Kendrick Barron

DO NOT USE THE SPREADER. Place a very small blob in the center of the CPU and then press firmly on the heatsink. Spreading the paste REDUCES YOUR EFFICIENCY and there are videos on Youtube demonstrating this. Lowered the temperature in my laptop from 90°C to 75°C at full load. It is worth buying if you need to paste again. The tube is tiny, but I've hardly used it on CPU and GPU dies. Most likely this will last a lifetime unless you fix computers for a living.
