Acoustic Samples: Listen to this Heatsink!
The waveform image shown below is out of scale for the level of noise the JMC Arctic Blast was measured to create (46.6 dB). We are still refining the process so listen to the heatsink and hear for yourself what this heatsink actually sounds like. Just click on the headphones and listen to 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.
The fan which at first seemed rather simple turns out to be one of the quieter cooling solutions we have looked at. The sound level of 46.6 dB is pretty low for a the heatsinks we have looked at and even slightly lower than the Zalman heatsink.
Synthetic Temperature Test Results: *Ranked according to 100W small interface die test results.
The JMC Arctic Blast is evidently a heatsink designed for older processors, and as we assumed, not part of a performance cooling line up. JMC list the Arctic Blast as useful for AMD processor of up to about 1.5GHz and that seems about right. The low noise levels are a plus, but can usually indicate the airflow is nothing special either.
Looking at the rise above ambient numbers we can see that the JMC Arctic Blast doesn't really pull in any performance level cooling numbers, and instead sits squarely in the class of OEM coolers.
On the small interface die at 100W the Arctic Blast ranks at the bottom of our list of reference coolers, which are not I might add, ranked according to specific types of processors. As always, we rank heatsinks according to their thermal performance.
The best ally of the Arctic Blast is undoubtedly going to be price, and while it will be able to handle older AMD processors, it really has no future with current chips. Perhaps a more powerful fan could be added which would change this somewhat, but limited to a simple aluminum extrusion there is only so much further this heatsink can be pushed.
On a positive side, the very thin fins are a welcome sight that would probably be good to carry further to future designs, and the low noise signature is admirable for a socket A/370 heatsink. Too bad the thermal performance on the small interface die isn't as endearing as that of the large interface die which does pretty well at 100W.
