Abstract: While the CEK787172 heatsink is dead basic, for older systems where cost and reliability is a factor it might be a good option.

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 Taisol CEK787172 heatsink had a surface roughness of approximately 32 microinches, which is considered good. The sanded surface is very slightly wavy from one edge of the base to the other indicating the raw extrusion may not have been machined flat prior to surface treatment.

Acoustic Samples: Listen to this Heatsink!

The Taisol CEK787172 produces about 50 dBA worth of noise under power. If the heatsink is installed in a low noise PC it will be audible, but for most typical PCs it should blend in well. 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.

As a heatsink with a 60mm fan, it is a little surprising to find the CEK787172 can actually produce 50 dBA worth of noise, but indeed it does. Up next, the thermal results!
