Kingwin RVT-9225, RVT-12025, and RVT-12025D CPU Coolers

Introduction

A little while ago, I received three CPU coolers from Kingwin. They sent TechwareLabs the entire HDT (Heat-pipe Direct Touch) line, the RVT-9225, RVT-12025, and RVT-12025D. As you might guess from the name of the series, these coolers feature the use of heat pipes to move heat from the processor. In the case of the Kingwin coolers, the heat pipes actually touch the processor directly, for much more effective heat transfer, at least in theory. While this feature is not unique in the industry, it is a feature this is preferable for the obvoius performance increase. In each of the models we will discuss, all of the heat pipes actually receive heat directly from the processor, as opposed to receiving the heat through a copper or aluminum block before being moved to the pipes. As this is a rather innovative idea, I was eager to test them out and see if the ingenuity actually paid off, and if Kingwin has built us a winner.

Meet the Coolers

RVT-9225

The original from the Revolution HDT series. This cooler stands upright and has a 92mm fan positioned to blow air across the heat sink. This cooler is compatible with Intel: Socket 775 CPU, Core 2 Extreme/Quad/Duo, Pentium Extreme Edition/D, Celeron D, and AMD: Socket AM2/754/939/940 CPU, Athlon 64/FX/X2, Opteron, Sempron motherboards. The cooler also comes with an air "spoiler" which, after air travels through the heat sink, you can direct it up or down, depending on your preference.

RVT-12025

This cooler is much like the first, only bigger. The heat sink is a full 25mm taller, and made to fit a 120mm fan instead of 92mm. The block with heat pipes is exactly the same as the original, except the pipes are a bit thicker, presumably to allow heat to travel away from the processor easier. This cooler is compatible with Intel: Socket 775 CPU, Core 2 Extreme/Quad/Duo, Pentium Extreme Edition/D, Celeron D, and AMD: Socket AM2/754/939/940 CPU, Athlon 64/FX/X2, Opteron, Sempron motherboards. Just like the first one, this cooler also comes with the air "spoiler" to direct air that has left the heat sink.

RVT-12025D

Though this cooler is in the same series as the other two, and uses the same HDT technology, it is otherwise nothing like the first two. Instead of blowing air across the motherboard, parallel to the surface of the CPU, the 12025D blows air directly at the main board, and the CPU itself. Air passes through the large heat sink, and then splashes off the aluminum block sitting on top of the processor, just for added measure. This cooler also sports 4 heat pipes, and a much wider (and cooler looking!) heat sink Just like the rest of the series, this cooler is compatible with Intel: Socket 775 CPU, Core 2 Extreme/Quad/Duo, Pentium Extreme Edition/D, Celeron D, and AMD: Socket AM2/754/939/940 CPU, Athlon 64/FX/X2, Opteron, Sempron motherboards. It does not have an air foil though.
