The Gelid GC1 Thermal Compound does exactly what it is supposed to do - adding a cushion between the processor and the cooler, and filling in any surface imperfections to enhance the thermal transfer between the CPU and cooler, and did it just as well as one of the top performers on the market right now, Arctic Silver 5. I was very impressed to see that at idle, the stock and overclocked temperatures were just about the same, and when the load was put on the processors, the GC1 was able to stay with the Arctic Silver 5 and even beat it in the Stock Load test.
