Fanless PCI Radeon?

VIAHardware has a review of a 64MB Radeon that fits in a PCI slot and on top of that it's fanless! Looks perfect for one of the sans-AGP Shuttle mini-barebones systems.

Check out the review here.

For Dilbert fans: PC Feng Shui

A hilariously appropos Dilbert strip about Feng Shui and noisy computer fans. Thanks to Tim Handley of VIA for pointing it out. :)

FrostyTech review of Zalman CNPS6500-Cu Fan Heatsink

FrostyTech.com has a very positive review of the Zalman CNPS6500-Cu Fan Heatsink. Notable for its audio recordings of the noise the Zalman makes, the review offers a comparison of the Zalman fan against many of its peers.

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 Overclockers.com(!?)

A story on quiet air-cooling of an XP1600+ system in Overclockers.com 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

Cases|Damping
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: www.KoolnQuiet.co.uk. 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

Fans|Controls
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.
