The Auras LPT-709 heatsink is equipped with soft rubber vibration absorbing fan posts, and a 92mm PWM fan that scales from 800-2400RPM. As you can see in the photo below, the cooling fins also have a bent profile, and staggered edges.

The Auras LPT-709 heatsink comes with two mounting brackets that allow it to be installed on Socket 775 Intel and socket 939/940/AM2/AM2+ AMD motherboards with a minimum of fuss. The brackets screw onto the copper base of the Auras LPT-709 with four screws, and after that installation is a tool-free affair.

Printed instructions are provided, but you won't need them. Faced with a pile of heatsinks lately that use unnecessarily complicated mounting hardware, Frostytech is really pleased to come across any heatsink that makes use of the standard AMD/Intel methods of attaching it to the motherboard.

Base Finish and Flatness

Flipping a heatsink over to inspect the business end is often a simple indicator of overall cooler quality. More practically speaking, a heatsink is in many ways only as effective as the contact it makes with the processor - the flatter and smoother the better. Base finish is one of the criteria that Frostytech measure in the course of evaluating heatsinks, and it involves two distinct aspects. Surface Finish is the first; this is calculated with the aid of Surface Roughness Comparator that has a cross section of common machine surface finishes and their numerical surface roughness equivalents in microinches. The second is Surface Flatness. This is tested with an engineers straight edge or proven flat surface, in two axis.
