Kingwin RVT-12025D

Kingwin has had tremendous success with their North American offerings of the Heat-pipe Direct Touch technology. In addition to product clones of the Xigmatek HDT-S1283 with their own Revolution RVT-12025 and, they have also released the RVT-12025D as a North American version of the Xigmatek HDT-S1284. Kingwin's RVT-12025D features 6-gauge copper heat-pipe rods compared to the 8-gauge rods in the HDT-S1284, but otherwise the designs are identical.

When I first learned of the Kingwin Revolution series at the 2008 International CES, I was excited to get my hands on the RVT-12025D because I hadn't seen the design yet. It appeared to have many of the same high-performance characteristics as many other CPU coolers we've seen of it's style, such as the Thermalright SI-128.

In many ways the Kingwin Revolution RVT-12025D is meant for low-profile installations, such as 4U cases or HTPC enclosures. Because of the overall height is almost 40mm shorter than the RVT-12025, this CPU cooler can fit in mid-tower cases with side-panel fans as well. The overall footprint is larger however, and will require a bit of finesse to install in confined areas.

There's a protect grill covering the fan, which is mounted to the finsink using soft rubber latches. We took these images with the fan installed, which is how the unit arrives, but all of our testing was conducted with a common fan.

The major trade-off between the vertical RVT-12025 and this horizontally orientated RVT-12025D is the number of heat-pipes making contact with the CPU. With a reduced rod size from 8-gauge down to 6-gauge, Kingwin was able to fit a forth heat-pipe rod into the aluminum mounting base. We'll soon see if this helped the performance against the larger gauge heat-pipe cooler.
