Acoustic Samples: Listen to this Heatsink!

The fan used on this heatsink does make some noise, but isn't really high-pitched in tone so the annoying factor is quite low. This may be due partially to how the fins are situated, but that is really hard to tell for sure, and pretty much irrelevant in the long run. :) To listen to the heatsink and hear for yourself what is 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.

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
	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 for a relatively high RPM fan. This heatsink is not intended to be a low noise cooling solution, but by keeping the high pitched noises for the most part of the equation it manages to keep overall noise levels within reason.

With the amount of copper used on the XPC5000 you are looking at a brute force attempt at cooling that pays off pretty well. I suppose there are more efficient ways to use this much copper, but for the most part there isn't much we can complain about how NengTyi's XPC5000 scored. The results, especially when compared to older NengTyi heatsink designs are simply very good.

The heatsink looks really cool, performs at about mid-level standards, and comes with a decent fan, but let's see what the rise above ambient results tell us.
