Xigmatek XP S964: You Get What You Pay For
The Xigmatek XP S964 uses a heatpipe design similar to that of the HDT S1283, but it lacks the direct-touch technology. The cooler includes four heatpipes that conduct heat to aluminum cooling fins cooled by a 92 mm fan.
Pushpins hold the cooler in the motherboard. The pushpin arrays are attached to the cooler with four screws. Since the motherboard does not have to be removed from the case, installing the cooler takes only a few minutes.
The XP S964 performs almost as well as its bigger brother. Under full load, it cooled our quad-core processor to 70.5 °C. It was rather loud, though, producing a noise level of 44.2 dB(A). When the CPU idled, temperature dropped to 39.5 °C with the fan reaching a very low noise level of 37.3 dB(A).
The XP S964 costs about $30.
