What type of CPU cooler contains heat pipes?

A CPU cooler that contains heat pipes is typically referred to as a heat pipe cooler or a heat sink with heat pipes. These coolers utilize a series of sealed copper or aluminum tubes (heat pipes) filled with a small amount of liquid that evaporates when heated, transferring heat away from the CPU to a larger heatsink or radiator. This design enhances thermal conductivity and improves cooling efficiency, making it a popular choice for both air and liquid cooling solutions.
