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 Titan TTC-D9TBcu35-R1 heatsink had a surface roughness of approximately 4L, which is considered excellent. Move your mouse over the 4L tab above to see a large scan of what this surface roughness looks like.

Acoustic Samples: Listen to this Heatsink!

The large fan on the Titan heatsink is really very quiet, and I highly doubt anyone will notice it in operation outside the PC enclosure. 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.

The low noise Titan TTC-D9TBcu35-R1 produces just 37.6 dBA under power - making it among of the quietest of socket A heatsinks we have tested. The fan speed controller does give you the option of turning the speed even further, but I don't this would be necessary.
