Tocools Crown Prototype Heatsink Review
Tocools Crown Prototype Heatsink Review

Abstract: So now that we have our Frosty little hands on this prototype cooler, what is so special about it?

Acoustic Samples: Listen to this Heatsink!

We're still refining the process of capturing an accurate waveform image of the sound a heatsink produces, so while this solid line of grey is accurate, it is out of scale. The Crown does make a fair bit of noise, but if you went by the graph alone it would look as though we were talking about a jet engine at full blast.

The best way to hear for yourself what the Tocools Crown sounds like with its 80mm Delta fan is to just click on the headphones and listen to the MP3 recording.

Sound Level Measurements:

Listening to the noise a heatsink makes allows you to hear things that pure numbers alone cannot get across, but to further emphasize Frosty's reliance on cold hard facts when evaluating a heatsink we also take Decibel readings with a sound level meter. The list of heatsinks which have had their noise level measured is still growing, but this is now firmly part of our test procedures.

FrostyTech Sound Level Results
- Manufacturer Model Noise Level Scale
Zalman All Flower HSF 47.4/28.9 dB quiet
Noisecontrol Silverado 50.8 dB
Thermal Integration Ti-V77L 53.0 dB
Tocools Crown 54.5 db
Dynatron DC1206BMP 65.1 dB louder

Tocools crown is a noisy heatsink which is over the 50 dB mark. The Dynatron heatsink with its 38mm Delta fan is very noisy by contrast, and is substantially over the next mark of 60 dB.

For a manufacturer we have previously not tested, and a heatsink which is still in prototype stages, the Tocools Crown, a massive heatsink by most standards, has managed to produced some very impressive initial results.

It has out-performed many all copper heatsinks, some of which have very powerful 60mm fans. The 80mm fan is definitely an asset, but the unique base design and overall construction seem to be working very well too.

Conclusion:

The final results for the Tocools Crown remain very impressive. Even though the heatsink is still in the prototype stages it has been given a good set of features to ensure it some very good first time performance. The 80mm fan is a big plus, and while the heatsink may be a bit large for some Socket A motherboards, it is at least a little bit quieter than those coolers with the 38mm thick 60mm Delta fans.

With some further refinement, the folks at Tocools should be able to improve on the pre production unit we had for testing, using a better clip mechanism, and greatly simplifying how the fan is attached to the heatsink body. The base finish is perfect, and we hope that future revisions continue to remain milled flat as this is the only way any heatsink should be finished.
