Ultra X-Finity ULT-XF500 power supply

This market-driven brand submitted another flashy, gleaming power supply for us to review. Among its many features, it is high powered, has a 120mm fan, and boasts unusual clear insulation cables. Do these add up to a PSU that SPCR can recommend?

Vancouver Gets Sound Smart

In the Dec 2005 issue of Vancouver's CityNews newsletter is a surprisingly progressive item of interest to anti-noise citizens everywhere:

Noise is often an inescapable part of living in a city the size of Vancouver. But, there are ways to make some noisy situations more manageable. The City of Vancouver has created Soundsmart, a three-part series for residents concerned about noise. The Soundsmart brochure is a brief rundown on noise basics. There’s also a 20-page comprehensive noise guide that helps you understand noise, and offers do-it-yourself ideas for reducing noise in your home. Both are available for free to Vancouver residents at City Hall. An in-depth 100-page noise control manual is available for $20. All three Soundsmart publications may be downoaded for free online at

All of these are very worthwhile downloads, especially the very in-depth Noise Control Manual. It is a pleasure to see one's own city take such initiative in a matter that's so often glossed over.

Squeezebox 3 Digital Music Box

This unusual product by Slim Devices is a bridge between a stereo and a PC. The visible portion looks like a large, stylish digital clock -- but it has a remote. The invisible portion is a music server software that runs on a PC anywhere within reasonable distance. A wide variety of digital music files can be accessed through the Squeezebox and played into the stereo. The connection to the PC is via ethernet, either wired or wireless. It's one of the most exciting PC products we've come across; it's also one of the most exciting audio devices. Our very first audio/PC component review.

The Deaf iPod Generation?

Canada's Maclean's magazine reported in its Dec 1 issue that over 27 million users around the world risk hearing damage because of the iPod's ability to play as loudly as 112 dB -- "louder than a chain saw" -- for hours on end. Reportedly, the EU has a 100-decibel cap on portable music players, but there's no such limit in the US or Canada.

Preview of Intel's Yonah... Vs. AMD X2

Anand managed to get hold of an early "Yonah" dual-core Pentium-M derivative processor from Intel, and a motherboard to go with it. The bad: It's not compatible with existing CPU sockets/boards. The good: Performance in most benchmarks is close to AMD X2-3800+, and power consumption is quite a bit lower at load. It's not clear whether the 108W and 144W comparison refers to AC power to the system or DC (I suspect the former).

How close this sample is to the production model, who can say? Still, it looks like AMD has a new target to shoot for; Yonah is supposed to be relased some time in the first half of 2006, perhaps even the first quarter. Anandtech's Yonah report.

Our favorite low cost quiet heatsink/fan maker has a new flagship with some unusual and innovative heatures. Multiple copper heatpipes and thin fins, of course, as in the original Freezer, and an improved "frameless" fan mounted with miniature soft rubber grommets. It's quite the cooling performer. What about noise? Read on to find out about Arctic Cooling's latest.

Quiet 7800GTX-512 Vidcard, too?

Previews and reviews of the 512 MB nVidia Geforce 7800 GTX video card flooded the web over the past 24 hours. While it is clearly not a silent solution, the reference card's 92mm fanned slot-venting cooling solution has been praised for its low noise. Perhaps the makers of video cards, the last bastion of the "Performance at any (noise) cost" mentality, have finally started to take acoustics seriously across the product line. The availability of low-noise video card solutions has grown by leaps and bounds in recent weeks.
