In order to get an efficient and effective heat exchange away from the CPU, which of the following is the most common solution?

Thermal paste functions similarly to grease in that it guarantees that heat generated by the CPU is efficiently transmitted away and into the heat sink. Thermal pads (paste) are typically preinstalled on new coolers (fan/heat sink combinations). Lowering the CPU speed may result in less heat produced, but it will inevitably result in decreased performance.
