Home > Reviews > Page: Surface Roughness Comparison

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 Thermal Integration TI-RV108N heatsink had a surface roughness of approximately 8M, which is very good. Move your mouse over the tabs above and look at 8G for an approximate example of what this surface finish looks like.

Acoustic Samples: Listen to this Heatsink!

The Thermal Integration TI-RV108N is not the quietest heatsink on the planet, but it is not quite as loud as the wave diagram below would lead you to believe. There is a whine to this heatsink that you will probably hear from outside the case. 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.
