Arkua 628 Copper Core Heatsink Review

Abstract: This heatsink has tested extremely well, which is a bit surprising for its small size.

Acoustic Samples: Listen to this Heatsink!

Finally we have some nice sound images to share with you! I tell you, as much as everyone likes these little sound clips of the heatsinks I sometimes think it would make things so much easier to just pass over them sometimes.... not that I would though. Okay, the Arkua 628 is about a 50dB heatsink and shouldn't really be too bad all things considered. Of course, to listen to this heatsink for yourself, simply click on the little pair of headphones and download the MP3 recording..

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.

FrostyTech Sound Level Results
- Manufacturer Model Noise Level Scale
JMC Prducts 400023 46.6 dB quiet
Zalman All Flower HSF 47.4/28.9 dB
Taisol CGK760092 48.4 dB
GlacialTech Igloo 2310 49.4 dB
Arkua 628 50.7 dB
Noisecontrol Silverado 50.8 dB
NengTyi XPC5000 52.4 dB
Thermal Integration TI-V77L 53.0 dB
Tocools Crown 54.5 dB
Cybercooler P5750 55.4 dB
Sibak AT01515B 55.8 dB
Sibak AC02625B 59.7 dB
Dynatron DY1206BH-625 63.3 dB
Dynatron DC1206BMP 65.1 dB louder

Anything under 55 dB is pretty decent, and at 50 dB the Arkua 628 does pretty well in this regard. The fan doesn't draw that much current so I would have to peg RPM's at about 5000. This is pretty standard of most 20mm thick fans.

Synthetic Temperature Test Results: *Ranked according to 100W small interface die test results.

Well it's not often that we see a heatsink jump right to the top of our list of reference heatsinks, but it appears as though the Arkua 628 may just be taking out the TI-V77L for once and all. With these heatsinks a lot of the cooling power comes from where the exhaust air is directed - directly at the heat source. Other heatsinks which exhaust all their warm air off to one side really aren't making good use of that air which is still substantially cooler then the processor.

Lets load up the final rise above ambient temperature results and see where everything plays out in the end.
