The Kingwin XT-1264 comes packaged in a retail box with plastic clamshell insert which holds the cooler and associated mounting hardware. This consists of pushpin style brackets for Intel 775 and 1366 sockets, as well as the preinstalled AMD style clips that support virtually any AMD platform including 754, 939, 940, AM2/+ and AM3. An instruction guide is also included for those that may be unfamiliar with the AMD or Intel mounting systems. Although many aftermarket coolers require a proprietary backing plate and attachment mechanism, the Kingwin cooler attaches to the stock motherboard retention bracket.

The XT-1264 is shaped in typical tower cooler fashion and measures in at 120mm wide by 150mm tall by 74mm thick. The included 120mm fan fits onto the 120mm wide fin section with a small portion of it overhanging the base, which is cut out to make room for the mounting clips. The four copper heatpipes curve out from the base in opposite directions, extending up through the tower and yielding eight attachment points through each fin for heat transfer. With fan installed the cooler weighs in at only 467g; the lack of a base plate and the mostly aluminum construction helping to achieve that low weight.

Rather than the RVT-12025's rubber pin fan mounts, the XT-1264 uses a more traditional metal clip style attachment, however this limits the range of fan use to only 25mm width units. The XT's included fan is a 4-pin PWM style rated at a variable 700 to 2300RPM, 82 to 101CFM and 34 to 38dBA. PWM or Pulse Width Modulation fan speed can be controlled by the motherboard BIOS if your board supports this, and typically offer such presets as "performance" or "quiet".

Although many tower style coolers share similar features, one aspect of the XT-1264 I've not seen used before is the extension of the base top plate up through the lower fins. Typically manufacturers rely on the heatpipes alone to convey heat to the fins, however here Kingwin is using an extruded aluminum pin top plate to disperse any residual thermal energy. This section is not supplied by airflow from the 120mm fan, but any part that carries heat away from the base should help reduce temps.

The older RVT-12025 included a detachable spoiler that could optionally be used to deflect some airflow from the exhaust side of the fins, down towards the motherboard to cool surrounding components such as power regulators. The XT-1264 makes this a permanent fixture, extending the width of the lower two fins and angling them down for the same purpose.

Now let's install the XT-1264 and perform some testing.
