Cooler Master announces line of "Silent Coolers"

Cooler Master has announced a series of "Silent Coolers". With options for Athlons, Celerons, Pentiums and most other chips, this line seems to be fairly comprehensive.

Details are sparse on the site, but the HSFs appear to be nothing more than a big heatsink with a large fan stuck on top of them. Some of the "Silent Coolers" have noise ratings as low as 26dB(A) while others range up to a migraine-inducing 38dB(A). It remains to be seen how Cooler Master intends to distinguish these HSFs from the rest of the very crowded field.

"Silence of the PC Lambs"

The Inquirer reviews SID Future Client from Signum Data
No, it does not feature Anthony Hopkins. It does, however, discuss life issues: "The only reminder you get that there is life in the PC is the blue light near the power button. It's so quiet that at first you keep checking the light just to reassure yourself that the machine is alive." The first review we've seen of this silent PC (mentioned in last week's news). Short and to the point.

Promising Fan-wiched CoolLink Heatsink

A new HSF by Cool Link, another Far East manufacturer, is equipped with a unique 2-fan design that appears well adapted for low airflow operation. A copper base plate, aluminum fins that run up and down on either side of a vertical central wall, a 70mm fan for each bank of fins, and a clip with slots for 3 socket lugs on either side gives the Cool H2Twin (H2T) a formidable image. With both fans removed, an H2T has been running for a week on a 1 GHz T-bird in place of the previous Swiftech MC462A under a Panaflo 80 mm L1A @5V. The short report: idle temp at 36C hasn't changed. Neither has the peak at 50C. More in a review to come soon.

Sortable Fan Specifications

One of the questions we hear most often is, "which fan is the quietest?" closely followed by, "how much airflow does it have?" Now, you can see for yourself. This site has detailed fan specifications for most of today's popular fans. The information seems to be accurate as well as up-to-date. A great resource when you're trying to figure out what to use to replace that noisy case fan.

Quiet that Mac

For all you Mac users out there, (at least those of you with G4s) Accelerate Your Mac has posted an article explaining how one person reduced the fan noise in his G4. This isn't just a typical replace-with-a-papst project. The author used a voltage regulator to reduce the voltage on his fan and removed some of the metal venting from around the PSU exhaust.
Nice to see some Mac-specific silencing information out there.

Everything You Know about Cooling & Heatsinks Is Wrong

So claims electronics cooling engineer Tony Kordyban in a series of interviews about "Doggone Thermal Design Questions" at The Cooling Zone. For those who seek the scientific fundamentals behind cooling, this piece is only one of an entire library of articles accessible at CoolingZone.com

"Hear Yourself Think"

"Hear Yourself Think" is the slogan behind the Noren Products Acoustilock series of PC enclosures.
Available in single PC configurations up to 14-space rack units, these products use a unique approach of acoustic insulation to reduce noise and heat pipes to dissipate heat. They claim up to an amazing 38dB(A) of noise reduction for their flagship model. No prices are listed on their web site, but chances are, these units are pricey.

A Case Mod, I think.

OK, so when I build a computer, I typically assemble all the parts outside of the case to make sure they work, because it can be a hassle to install everything into the case, only to discover that one component is broken and needs to come out again.

That's what these guys did, only they forgot to install the components in the case when they were done.

And then they sprayed everything with polyurethane foam.

The result is certainly interesting. Kind of the Frankenstein version of Disneyland's Matterhorn. I'd say it definitely puts a damper on the upgrade possibilities.

The Invisible Case

This doesn't strictly related to Silent Computing, but I have a weakness for ultra-cool case mods. Not just the same-old boring case windows but unique, innovative case mods.

This guy has built a custom "invisible case" from scratch, using plexiglass and elbow grease. The project took three months to complete and the results are impressive.

The article is fairly long and contains a detailed, step-by-step explanation of how he built the case. There are plenty of images at the end of the article to show you the final result.

New GeForce4 Video Cards Continue Noisy Trend

Tom's Hardware has reviewed three early versions of the recently-released NVIDIA GeForce4 Series of video cards. ASUS, Creative Labs and Leadtek all sent prototype GeForce4 Ti4600 boards to be put under the microscope. As might be expected from NVIDIA's top of the line model, performance was excellent, trouncing the competition (and NVIDIA's older cards) in every category.

Unfortunately, all three cards reviewed have large heatsinks and fans that don't appear to be quiet. With descriptions ranging from "bearable noise levels" to "sound bears resemblance to that of a blow-drier", this doesn't bode well for Silent PC enthusiasts.

For now, I'll stick with my fanless LeadTek GeForce2MX.
