Today, I will be reviewing Kingwin's 120mm version of that cooler, the RVT-12025.
Kingwin is one of those companies that many enthusiasts often overlook. The name has not previously been associated with higher quality and performance hardware, but lately they have really stood out with their upper-end SLI certified PSUs, high-tech CPU coolers and very attractive HDD enclosures.
Besides the Kingwin RDT-9225, I have also reviewed one other brand of cooler with exposed heatpipes. I have realized that the main purpose for exposing the heatpipes is to be able to lighten the cooler base, both by reducing it's actual size, and allowing for a much more effective use of aluminum, rather than the more efficient but much heavier copper. The primary transferal is taking place directly from the CPU heat spreader to the exposed copper pipes.
There is a trade-off… more efficient transfer from the CPU to the heatpipes themselves, but less actual contact surface area, due to the smaller base, and gaps between the base and copper tubing. In my comparisons between various 92mm coolers, both with and without exposed heatpipes, the cooling efficiency was about the same, with the benefit from the exposed heatpipe coolers being lighter overall weight.
I have been using 92mm coolers exclusively for quite some time, at least five years, and they have served me very well. I happened to have had CPUs that ran fairly cool, and the Q6600 Core 2 Quad I will be using for today's testing is no exception. But, some of the higher performance models of the Core 2 Duo, such as the Extreme models, run quite hot, and a 92mm cooler isn't enough to keep load temps under that magic temperature of 50C. This 120mm cooler should definitely help cool those heated processors. Read on and see.
The RVT-12025 comes in this attractive hanging cardboard box. Pretty much any features and specs that you would want to know are noted on the exterior. The cooler is protected inside by cardboard supports.
