Arctic Cooling NV Silencer 5 - Page 5 of 5

SOUND
There's really not much to say about the noise level. Once I couldn't even hear it running with my system powered up, well, that was enough for me. This thing is very quiet (0.9 Sones to be exact). I could not be happier with how quiet the Arctic Cooling NV Silencer 5 is.

From Arctic Cooling's website (link):

Noise Level
All measurements are taken using full fan speed.

The noise level is measured in Sone (loudness) instead of dB (sound pressure). The loudness depends upon ears response curves and tells you exactly, how bothering a certain noise is. Sone takes the frequency and bandwidth of a sound into account.

A doubling of the number of Sones sounds to the human ear like a doubling of the loudness.

The comparison of products from different manufacturers is basically impossible, since all manufacturers measure in different ways. Even a rough translation from Sone to dB doesn't help. A 15dB cooler can be louder than a 1 Sone cooler from another manufacturer.

Nevertheless with the Sone data you can compare our coolers between each other and get a quite precise idea how annoying the product will be.

1 Sone: nearly inaudible in a computer case
2 Sones: clearly audible
3 Sones and more: disturbing

CONCLUSION
I cannot stress enough that you should approach the installation of an Arctic Cooling Silencer NV 5 with patience and persistence. That is not to suggest that you'll have the same experience that I did. You could just as easily be able to install it on your first attempt and have excellent cooling results right away. I'd be doing you a disservice though if I glossed over what was necessary for me to achieve my excellent end results.

For those of you with a 6800 GT, you can expect to have even greater temperature reduction. The Arctic Cooling Silencer NV 5 is a huge leap past the stock 6800 GT cooling. It is not as dramatic an improvement over the already excellent 6800 Ultra stock cooling but still pretty impressive. Your mileage may vary, but if you stick to it the rewards are sure to be well worth the ride.

I'd like to thank CrazyPC.com for providing the sample for this review.

PROS

  • Quiet, basically silent
  • Good price/value
  • Innovative fan design
  • Impressive cooling of 6800 Ultra, even when overclocked
  • Stronger screws than original NV 5

CONS

  • Memory pads may be too thick or uneven, requiring sanding
  • Instructions not for 6800 Ultra
  • Confusing specifications between website and packaging

Please feel free to ask any questions or post any comments in this thread of our forums.

CHANGE LOG

  • February 15, 2005 - Updated page 4 with note that I had already removed the stock thermal compounds in my review of the BFG 6800 Ultra OC. At that time I then replaced with Arctic Silver 2 on the GPU core and Ceramique on the memory modules.
     
  • February 15, 2005 - Updated page 5 with PROS/CONS section.
     
  • March 23, 2005 - Updated page 1  and page 4 with ambient room and case temperatures.
     
  • June 10, 2005 - Updated page 1 with notice about Rev. 1 and Rev. 2 version of this product. Added link to this section of the review's thread in our forums for more information.
