XIGMATEK LOKI SD963

On the test bench today is Xigmatek's mid-compact Loki SD963 heatsink. The Xigmatek Loki SD963 stands 134mm tall, weighs 430 grams, comes equipped with a 92mm fan mounted on rubber vibration absorbing fan posts and will support a second 92mm fan if desired (not included). The 92mm PWM fan scales in speed from a moderately audible 2800RPM to 1200RPM. The heatsink is compatible with Intel socket 775/1155/1156/1366 and AMD socket AM2/AM2+/AM3/AM3+ processors. Over the next few pages Frostytech will tell you if the Loki SD963 is worth its weight in aluminum, or junk for the recycling bin. Let's begin.

Xigmatek have built the Loki SD963 heatsink for compact computer systems which cannot accommodate +155mm tall CPU coolers, but whose users still want good performance and modest noise output. Standing just 134mm tall, the Loki has a footprint of 94x76mm which is pretty compact in this day and age.

With an eye towards noise reduction the 92mm PWM fan is held in place on the aluminum fins of the heatsink with four vibration absorbing rubber mounting posts. These fit through the standard screw holes in a vaneaxial fan frame and keep the fan elevated 2.0mm away from the metal.

The nice thing about rubber fan posts is that when a fan motor happens to develop vibrations down the road (usually as a result of dust buildup in the impeller) the rubber 'shock absorbers' can reduce it slightly. The bad thing about rubber fan posts is installing the fan over them in the confines of a case, or worse yet snapping a rubber post in half!
Heatsink Installation
Xigmatek's Loki SD963 heatsink is compatible with Intel socket 775/1155/1156/1366 and AMD socket AM2/AM3 processors. The heatsink comes with one rear metal support bracket for Intel/AMD motherboards that will require access to the back. Depending on the computer case you may need to remove the motherboard to install this heatsink. After the upper metal stand offs are installed, subsequent CPU swaps are more straightforward.

AMD platforms make use of the same basic heatsink brackets, which is a shame since AMD supplies a heatsink retention cage on every single board.taken from : www.frostytech.com
