Akasa Venom Nano Heatsink Review
Akasa Venom Nano Heatsink Review
Abstract: Akasa's Venom Nano heatsink stands 150mm tall, weighs 560 grams and installs onto AMD socket AM2/AM3 and Intel socket 775/1156/1366 processors. Off the cuff though, it seems a little modest for Intel Core i7 use, dito for AMD Black Edition chips.

Information on Frostytech's test methodology is available here.

The 110mm PWM fan spins at 600-2500RPM and draws power from a standard 4-pin motherboard fan header. Four rubber vibration absorbing posts hold the fan in place. The three 6mm diameter copper heatpipes are spaced about 12mm apart on center and rise up through the 0.4mm thick raw aluminum fins. Fins are spaced 2.0mm apart.

The Akasa Venom Nano heatsink stands 150mm tall, the bottom-most fin being 41mm above the CPU socket for clearance. The base incorporates a 12mm thick aluminum section to provide support for for the exposed heatpipes and mounting brackets.

Looking at the top of the Venom Nano heatsink the three 6mm diameter heatpipes are seen passing through the aluminum fins in a straight row, towards the outer edge of where the fan rests. The base of the heatsink measures 35x38mm in size and features three exposed copper heatpipes set widely apart (6mm space between each).

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.

Akasa's Venom Nano heatsink has a surface roughness of approximately 32 microinches, which is considered good. The base has a sanded surface finish and is perfectly flat in both axis. The copper and aluminum segments are flush.

Sound level measurements are coming up next.
