The Kingwin XT-1264 has proven to be a worthy successor to their RVT line of coolers, displacing the 12025 as the 120mm HTC tower style king. With the addition of an extra copper heatpipe, the XT-1264 features a base with the pipes much more closely packed than that of the RVT-12025, which translates into better heat transfer and temperature handling capacity. While shortening the tower slightly, a boon to those using narrower, mid-tower cases, the fin structure on the XT-1264 is noticeably thicker, about 25mm or so, yielding over 30% more surface area. Surprisingly Kingwin was still able to reduce the weight from the RVT-12025 by about 130g or roughly 20% less. The 120mm fan also has slightly different specs than the model used on the old cooler, producing a few more CFM, albeit at a significant dBA penalty.
If I had to complain about one thing with the XT-1264 in fact it would be the fan. While not exactly what I would call "noisy", with a 32 to 38dBA range it's far from quiet either. If you have the ability to reduce the fan speed using the PWM controls built into your motherboard BIOS, a reduced "quiet" setting may be just the trick to quelling most of the vibrations and excessive airflow. But the old unit's fan produced nearly as much flow with significantly less sound volume, it's a shame Kingwin had to change it.
But fortunately it's easy enough to swap on any standard 120mm x 25mm fan, and even a much more silent one coupled with the XT-1264 only hurts the performance by a few degrees. And if you don't mind a bit of noise, well then the 1264 is right up your alley as-is. The cooler keeps temperatures well under control.
I found the Kingwin XT-1264 online for just under $40, which is a slight increase compared to the model it replaces. But it's still much cheaper than most high-end air coolers, and the improvements this version brings to the table make up for it's higher cost.
