Zalman VF700-AlCu VGA Heatsink Review
Zalman VF700-AlCu VGA Heatsink Review
Abstract: The Zalman VF700-AlCu heatsink is intended to cool overworked videocards quietly. The heatsink is constructed of the same fan-shapped fin design that has made Zalman a well known manufacturer.

Sound Level Measurements: Which Heatsink is Quietest?

Because most fans used with videocards are fairly quiet we're omitting the fan noise recordings for this segment of heatsinks. Instead, FrostyTech will emphasize its reliance on cold hard facts when evaluating different thermal solutions by providing the following noise level measurements taken with a digital sound level meter in a noise-proof chamber. VGA Heatsink Noise Level Measurements
Noise level Decibel measurements of each heatsinks' fan in operation are taken with the aid of a sound level meter and sound isolating enclosure. The values may be higher than the mfgr's listed specs, but are directly comparable to one another. Measurements are made on the dB (A) scale. Information on Frostytech's test methodology is available here.
manufacturer: model no.: *fan speed: noise level (dba):

Zalman VF700-AlCu low 32.6 dB Quiet
Zalman VF700-AlCu LED low 32.9 dB
Zalman VF900-Cu low 33.5 dB
Zalman VF900-Cu high 42.0 dB
Zalman VF700-AlCu high 43.1 dB
Zalman VF700-AlCu LED high 43.3 dB
Albatron Stock FX5900 Heatsink 48.0 dB Loud
noise level (dba)
*unless noted, for reference heatsinks with variable-speed fans only the 'high speed' (12V) fan noise measurement is included in the comparison sheet; more detailed results for the low fan speed (~5V) tests reside in each specific heatsink review.

With the Zalman VF700-AlCu heatsink running at its stock 2650RPM speed, noise levels hover around 43.1 dBA. If the fan is supplied with 5V DC the speed drops to 1350RPM and noise to a little under 32.6 dBA.

Surface Finish Comparator Notes: Flatness and Finish

Surface finish is an important factor that we all look for when holding a new heatsink. Flipping a cooler over to see how well the base has been machined is a quick way to judge the attention to detail that was put into making it. The following test involves the use of a Surface Roughness Comparator, which offers a concise cross section common machine surface finishes.

The Zalman VF700-AlCu VGA heatsink has a surface roughness of approximately ~8 microinches, which is considered excellent. Next, let's see how this VGA heatsink handles the heat compared to a small selection of other videocard heatsinks!
