Silent PC Review is passionate about ergonomic spaces for people and finding creative, practical solutions to silencing all kinds of IT machines. We provide detailed reviews and ground-breaking knowhow about the acoustics of computers and components, as well as their energy efficiency and thermal performance.

Ultimate Underclock & Undervolt Project

Do-It-Yourself Systems
New contributor Leo Velikovich shares an impressive PC silencing project which involves underclocking and undervolting not just an AMD XP1700+ but also a hot GeForce 4 Ti4200 video card. Is it the Ultimate Underclock & Undervolt Project?

Quieting an XP at!?)

A story on quiet air-cooling of an XP1600+ system in just appeared today. Nothing revolutionary to regular SPCR devotees, but interesting, and noteworthy that one of the web's great overclocking communities, normally oblivious to noise, is beginning to rouse to the deafening noise.

Shuttle SS51 officially launched

Shuttle, the leading developer of innovative small form factor (SFF) computing solutions, today launched the latest model in its rapidly expanding XPC product line. Widely regarded as the pinnacle of Small Form Factor design, the Shuttle XPC line are poised to become the standard for next generation PCs.

Brown Bread noise dampening

Member Ken Sakuma reviews the noise reduction effect of "Brown Bread" panel dampening material on a PC system that is already carefully tweaked for low noise. The review answers questions not only about BB but other similar materials such as Dynamat.

CPUs Ranked by Noise

A new addition to the Recommended section, just about every CPU released in the last half decade is ranked by COOL factor. Cool in our book equals quiet; it is a noise-ranked list. It should be useful whether you're seeking to quiet an old system or assemble a new quiet one.

KoolnQuiet: New UK e-tailer for quiet stuff

A new UK e-commerce site has just been launched: As the name implies, they only sell components that keep computers cool and quiet. A couple of informational pages present a good summary of problems & solutions. Hopefully, KoolnQuiet will turn out to be a nice resource for those on the other side of the Atlantic.

Temperature Controlled Fan

For the budding electricians among us, here is an interesting article on how to make your own temperature-controlled fan. Containing simple as well as linear models, this project isn't for the mainstream silent pc enthusiast, but is a great idea for those who like to tinker.

Nvidia and Shuttle to produce new SN40 system

Nvidia and Shuttle announced today their partnership to produce Small Form Factor nForce2 barebones, a move which should see improved performance from the tiny PC. We can expect many of the nForce2 features to be integrated into Shuttle's upcoming SN40 including:

Choosing Fans for Quiet, High Airflow: A Scientific Approach

Contributor TheBigFan used fan laws and sound equations to calculate the theoretical airflow and noise levels of 111 selected DC fans at reduced speeds, multiples and different configurations. This fascinating article sums up the thorough research and thoughtful analysis of a self-professed noise fanatic to identify the quietest fans that cool well. The data is downloadable as xls, pdf or zipped xls files. A very worthy addition to SPCR's growing knowledge base!

Tom's Hardware review of the Shuttle SS40 Mini PC

Tom's Hardware has an article about the Shuttle SS40 PC. The author practically gushes about the SS40 and gives it high praise. There are some great, detailed pictures of the mini-pc's heat pipe heat sink along with a decent explanation of how heat pipe technology works. Those two things alone make the article worth reading. Also mentioned is the fact that Shuttle will be releasing a replacement for the SS40 soon, which will contain an AGP slot, perhaps the biggest gripe heard about the SS40 today.

Zalman fanless VGA-heatsink/heatpipe due in August

Zalman says their new VGA heatsinks with heat-pipe(ZM50-HP, ZM80-HP) will be available early August and prices are not decided yet. Thanks for the tip, Patric.

AMD Shipping Athlon XP SFF!

Xbit labs reports that AMD just started shipping Athlon XP SFF processors featuring low power consumption. These CPUs utilize a bus speed of 100 (200)MHz instead of the common 133(266)MHz, and the supported Vcore ranges between 1.05-1.45V, which allows reaching only 35W heat dissipation level. Should make it easier to build quiet XP-based systems. Thanks to Alex Hu for the news tip!

Mini-ITX Web Site is a site devoted to (surprise!) all thing related to the Mini-ITX platform recently developed by VIA. Our review of the VIA EPIA-5000 Mini-ITX embedded CPU integrated motherboard remains the most read article on SPCR. Many projects and concepts are covered at, including silent and simply cool PCs. Well worth a visit.

Silent Supercomputing

The New York Times is running an article (free registration required) about two very different supercomputers. One supercomputer, called Q, follows the traditional path of packing as many teraflops into one computer as possible, without regard to power or heat requirements. The other computer, called "Green Destiny" takes a different approach. Relying upon low-power, low-heat chips from Transmeta, this computer is made up of a Beowulf cluster of machines and requires just a fraction of the power of the larger Q supercomputer. While the article doesn't fall within the traditional boundaries of silent personal computing, it's still worth a read.

Seagate announces larger Barracuda drives.

Seagate announced a new, larger Barracuda V series of hard drives. Using the same technology that made the Barracuda IV series so popular with quiet PC enthusiasts, these new drives will support 60GB per platter and support Serial ATA in addition to "regular" ATA. In addition, the Serial ATA drives, expected to ship later this month, will offer an 8MB cache, which should make for a nice increase in performance on these 7,200RPM drives.
