Vantec VP4-7245 Aeroflow 2 P4 Heatsink Review
Vantec VP4-7245 Aeroflow 2 P4 Heatsink Review
  78%   
Abstract: Vantec's entire socket 478 heatsink weighs in at 472grams, and interestingly enough, gets by with just a 70mm fan; odd since 80mm fans are the standard these days.

Surface Roughness Comparator:

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 FrostyTech Surface Roughness Comparator offers a concise cross section common machine surface finishes. Not every heatsink base will fit into the envelope of this gage, but it does offer a very handy set of representations.

This commercially available gage has 22 machined surfaces from 2 to 500 microinches; Lapped (2, 4, and 8 µ" RA), Ground (8, 16, 32, and 63 µ" RA), Blanchard Ground (16 and 32 µ" RA), Shape Turned (32, 63, 125, 250, and 500 µ" RA), Profiled (63, 125, 250, and 500 µ" RA), and Milled (63, 125, 250, and 500 µ" RA).

The base of a heatsink plays an important role in how well the cooling apparatus interfaces with the processor. Poor surface roughness will affect a good heatsink just as much as a good surface finish will improve thermal conductivity. In an effort to put a more quantitative spin on the comments we provide about base finishes, FrostyTech has begun using a Surface Roughness Comparator.

Move your mouse over the image above to see an example at right. Numbers are in Microinches, and finishes from 2 microinches to 32 microinches are excellent-to-good.

Evaluation Notes:

The Vantec VP4-7245 heatsink has a surface roughness of approximately 8microinches, which is considered very good. Move your mouse over the tabs above and look at 8M for an approximate example of what this surface finish looks like.

Acoustic Samples: Listen to this Heatsink!

The Vantec Aeroflow2 isn't all that loud, and should blend in for the most part in typical computer systems. Low noise PC users will find the 56 dBA sound output too loud for their tastes, however. To listen to this heatsink for yourself in operation, be sure to click on the little headphones icon below and download the Acoustic Sample MP3 file.

Sound Level Measurements:

Listening to the actual noise a heatsink makes allows you to hear what pure numbers alone cannot get across. To further emphasize FrostyTech's reliance on cold hard facts when evaluating a heatsink, we also take Decibel readings with a sound level meter. These results may be higher than the manufacturer's listed specs, but then again these are real world measurements. Measurements are made on the dB (A) scale.

White not a low noise heatsink by any means, the Vantec Aeroflow2 just doesn't seem as loud as it would appear in this reference list. Still, 56 dBA is getting up their in terms of noise output. Up next, let's see if all this noise is worth it!
