NEC desktop quiets down

According to this article on, NEC is releasing a desktop computer based on Transmeta's Crusoe chip called the "NEC Mate". As the article states, "It's so quiet...that the only noise it makes sounds like rustling leaves." Certainly sounds promising, but unfortunately, NEC has not announced plans to bring it to the US Market yet.

The Silent PC discusses PC Noise

Anyone who's been in the Silent PC arena long enough has visited Tomas Risberg's excellent site. Recently, I noticed a new section posted on his site, entitled, "PC Noise" which provides a very insightful, thorough analysis of PC Noise; where it comes from, why it bothers us and how to measure it. Worth a read.

A drive quieter than the Seagate Barracuda IV?

Since its introduction late last year, the Seagate Barracuda IV has been the quietest drive on the block. Well, according to Storage Review, that title no longer belongs to the Barracuda IV. Who's the new king of the hill? Another Seagate Barracuda. A SCSI version of the Barracuda. As the Storage Review charts show, the Barracuda 36ES2 measures a full 2dB(A) quieter than the 80GB Barracuda IV. Part of this is due to the single-platter design of the 36ES2 compared to the dual-platter design of the 80GB model. Still, for the SCSI enthusiasts out there, this is certainly good news!

Not just your average "How I built my silent pc" site

Mirar, one of the regular contributors on the Yahoo Groups Silent-PC mailing list, has posted his experiences in building a silent PC. Much of Mirar's work focuses on building a custom case, designed to reduce noise as much as possible. To quote:

I decided to design and build a case that would address this. The needs would be:

  • Silence. It would need to be heavy and dampening enough. A thin metal case is not the way; perhaps with heavy dampening mats.
  • Cold. It would need air ducts wide enough to handle lot of air without turbulence, and lots of spaces for fans.
  • Space. It should be easy to work in; not much screwing and pulling out irrelevant cables to remove a hard disk. Or a PCI card.
  • Simplicity. I should be able to build it. And I'm not /that/ handy with tools.

The result is very effective, if not all that pretty. :) Lots of pictures and explanations -- definitely worth a read.
