Utilizing the highest order of technology is their cooling fan: pulse width modulation, Xigmatek has combined the efficient design of three exposed copper heatpipes with an extremely durable (and quiet) 120mm fan in their newly released HDT-S1283. Pulse Width Modulation is usually regarded as too complicated for PC fan speed controls, especially when compared against rheostats or linear voltage regulators. Xigmatek cuts no corners in producing a top of the line CPU cooler worth it's weight in gold... or perhaps copper based on the costs of material these days.
When I first received the HDT-S1283 Exposed Copper Heatpipe 120mm CPU Cooler, I silently thanked Xigmatek for designing an after-market cooler which doesn't require me to disassemble my computer and remove the motherboard just to install a CPU back plate. With Anti-vibration rubber, spoiler design, and push-pin & clip systems for both Intel and AMD application, the HDT-S1283 offers an easy to install cooling solution.
From the side view above, you get a very good look at three of the largest copper heatpipes I can recall seeing on a CPU cooler. Xigmatek uses 100% copper in their 8mm heatpipes, which dramatically improves the evaporation and condensation cycle in the HDT-S1283.
A single 120mm cooling fan is included with the Xigmatek HDT-S1283, which is more than enough to move a large amount of air over the fins and heatpipes. After you see the results (keep reading, don't skip to the results page), you will understand why I am not going into detail about attaching a second 120mm fan to the backside of the heatsink.
The backside of the unit (shown in the image below) has a curved "valley" indention, which really serves no true purpose in this design. I think that if I were to ever design a "fin-sink" plate, it would utilize as much footprint space as possible; adding curves might look nice, but they take away from the cooling surface.
For Intel motherboard users, the Xigmatek HDT-S1283 Exposed Copper Heatpipe 120mm CPU Cooler must first be installed without the fan attached, and once the pins are depressed into the motherboard you can mount the fan. Once each of the four depression clips secures the heatsink to the motherboard, the soft rubber T-hooks press into the aluminum fin channel as shown in the image above. Installation was among the easiest I have ever experienced, which amounted to only one extra step more than the OEM cooler supplied by Intel.
The most critical part of any heatpipe cooler is the arrangement of the actual heatpipe rods. In any heatpipe design, the liquid inside the rod is heated to a very low boiling point. This low boiling point evaporates the liquid into a gas, which carries the heat to the ends of the heatpipe. Once it reached the cooler end(s) of the heatpipe, the chilled gas condenses into a liquid, which will then travel back down to the base for a cooling effect.
The real benefit I see to the design of the HDT-S1283 is two-fold:
A closer look at the mating surface on the Xigmatek HDT-S1283 shows the three exposed copper 8mm heatpipes resting in an aluminum base. The Intel depression-clip rails attach by a single machine screw at each end, as you can see by the threaded screw holes in the base shown below.
When applying thermal interface material to the Xigmatek HDT-S1283 exposed copper heatpipe 120mm CPU cooler, it's very important to understand that most white zinc-oxide (white) thermal paste will cause oxidation to the copper heatpipes upon contact and possible decrease the effectiveness of the material. Benchmark Reviews offers a complete guide on the Best Thermal Paste Application Methods, which includes instructions for HDT coolers.
At the moment, Xigmatek's HDT-S1283 CPU cooler is just turning one year old. There are a multitude of products that are either similar or identical, which is fair considering that Xigmatek doesn't own the patent for HDT anyway. Presently the HDT-S1283 is available from NewEgg for $36.99. Alternatively, NewEgg also offers the RVT-12025 for $31.99, which is considerably less expensive and is an exact clone (but comes with a much lower-volume fan for reduced noise levels).
