Xigmatek Dark Knight S1283 Heatsink Review
Xigmatek Dark Knight S1283 Heatsink Review
Overall Rating:   86%
Abstract: The S1283's fan has been swapped out for a smoky translucent plastic, and four white LED's illuminate the spinning blades. Otherwise you get three heatpipes in direct contact with the top of the processor.

FrostyTech Mk.II Synthetic Thermal Heatsink Test Results
Intel Pentium D / Extreme Edition & Quad Core class heatsinks tested at 150W
Intel Core 2 Duo / Pentium 4 / Celeron class heatsinks tested at 85W

Results based on readings from a 30x30mm copper interface die with 150W and 85W heat loads applied on the LGA775 version of the Mk.II Test Platform. Temperature results listed for each heatsink were calculated by determining the rise over ambient temperatures at time of test. Information on Frostytech's test methodology is available here.

*Heatsinks are ranked according to the 150W thermal test results column (rise over ambient temp.). Low temperatures with low noise levels are considered best. For reference heatsinks with variable-speed fans, only the high speed (12V) fan test result is included in the comparison sheet; more detailed results reside in each specific heatsink review.

Heat output from socket 775 Intel processors varies, so Frostytech tests with two thermal values that represent the upper limits of existing CPU families. With a 150W heat load applied by the Intel LGA775 version of FrostyTech's synthetic thermal test platform first, the Xigmatek Dark Knight S1283 heatsink maintains a temperature of 17.9°C over ambient (49.6dBA noise) at full fan speed. This is an excellent result for an Intel heatsink, and thrusts the Xigmatek Dark Knight S1283 heatsink into the Top 5 Chart!

For the next test the 120mm fan speed was reduced from 2200RPM to 1000RPM, decreasing noise levels to a very quiet 37.6dBA. In this scenario the Xigmatek Dark Knight S1283 heatsink held steady at 23.4°C over ambient - better than most Intel heatsinks are able to achieve at full fan speed, but not quite as low as the un-plated HDT-S1283 model.

Xigmatek's Dark Knight S1283 heatsink was then tested on the Frostytech Mrk.II synthetic thermal test platform with an 85W heat load; akin to a Core 2 Duo processor. In this test the Dark Knight S1283 maintained a nice 11.0°C rise over ambient temperature at default fan speed, and 15.3°C at its reduced fan speed.

In comparison to the originally Xigmatek HDT-S1283 model, the Dark Knight S1283 heatsink is nearly identical but a little less able at slower fan speeds. The dark nickel plating adds another layer for heat to cross, so it can slightly impede cooling. Still, Xigmatek's Dark Knight S1283 heatsink operates very well at full fan speed on both AMD and Intel test platforms, and would be a worthy heatsink for high performance cooling.
