Auras' LPT-700 heatsink is assembled from about 52 thin aluminum fins stacked on the three 6mm diameter copper heatpipes. The copper base is a rather thin plate, but it's soldered to the flattened copper heatpipes. The aluminum fins aren't nickel plated, so heatpipe-to-aluminum fin joints are not soldered.

The Auras LPT-700 heatsink comes with an LGA775 rear motherboard support plate that allows it to be installed on Socket 775 Intel motherboards with a couple screws. Four spring tensioned screws slip into the injection moulded aluminum support bracket that also frames up part of the LPT-700 heatsink. These catch the rear support plate and firmly hold the 500gram heatsink in position.

Printed instructions are provided, but the process is pretty simple. Users will need to remove the motherboard from the computer case to install the rear support plate first, but after that getting access to the CPU again isn't difficult.

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.
