Thermal Load Calculator by Innovatek

Internet News sent us word of a Thermal Load Calculator by Innovatek which works out how much heat is produced by a standard or an overclocked PC. The page is in German but the calculator is intuitive. It looks much more accurate than 99% of all such power calculators on the web, and should be fine for "sizing" PSUs if all the pertinent data is correctly entered. Only the Northbridge vs Northbridge und Mosfets choice under Motherboard give pause; surely you cannot separate the motherboard VRM from the NB in any calculation of motherboard power draw? This is the only feature that seems suspect.

SPCR v2.0 - Site redesign, visual & functional

Site News

The look, organization and feel of Silent PC Review was changed early this evening (Sunday, April 16, 2006). It is the first global change made to the site since the launch over four years ago. The visual changes are easily seen, but the functional ones are a bit less obvious. You will see them as you navigate through the various sections.

One of the major changes is the listing of complete summary information for articles (listed in reverse chronological order) in each category, including date, title, and fully summary. There are other more subtle ones, such as certain cross-topical articles appearing in more than one category.

The article index has a variety of user options for listing SPCR contents. A lot of people have asked for this in the past. Try playing with it; it should help you find articles more easily.

We think the organization of and access to information is improved. For administrators and content creators, the back end changes are immensely beneficial and will shave at least half an hour of coding work on any article. We hope you enjoy the new design. It's been in the making for many months.

SPCR regulars have already begun a discussion about these changes

Run Windows XP on iMac with Boot Camp

Internet News

PC World reported, "It works. Impressively well. With games, even. That's our first impression of Windows XP running under Apple's [beta version of] Boot Camp on our 20-inch iMac. And that's more than you could say a couple of days ago about the promising-but-hacked-together WinXPonMac effort."

Silent PC Review Turns 4 Today

Site News

Today, April Fool's Day 2006, is the 4th anniversary of SPCR's official launch. It started as a crazy hobby... and mushroomed over the years into the web's leader in PC acoustics analysis and information. We've also learned much about thermals and power efficiency in all kinds of PC products, which puts us in good stead in a new computing era of green activism that's starting to pick up steam.

My heartfelt thanks to all the people whose support, encouragement and participation helped to make SPCR what it is today -- visitors, forum members, advertisers, sponsors, contributors, writers, advisors, friends and family. (For more about how SPCR came to be... A Cautionary Tale?)

Desktop Core Duo Products Coming Soon

Internet News

Apple's new iMac may have been the first to use Intel's new power-efficient Pentium-M derived Core Duo on a desktop PC, but they certainly won't be the last. Joining AOpen with new Core Duo/Solo (and Pentium M) products are Asus, Shuttle, ECS, MSI and Gigabyte. It seems clear that Intel is successfully marketing the new low-power processors to the mainstream desktop/small server market. Thus far, however, Intel's major system integrator partners (Dell, HP, etc) are only featuring Core Duo processors in notebook PCs.

AOpen: i975Xa-YDG and i945GTm-VHL Core Duo motherboards; mini-PC MP945
Asus: N4L-VM DH Core Duo Viiv motherboard
XPC X100 Complete SFF Core Duo PC
: PF23 Crossfire-compatible and 945G-M3 Viiv motherboards
MSI: P1-104A2M P-M server and 945GT Speedster-A4R P-M motherboard
Gigabyte: A963 Core Duo/Solo MiniPC

Then there are all the mini-ITX boards for Core Solo / Duo:

Commell LV-677 (m-ITX)
AOpen i945GTt-VFA
DFI G5C100-N
Freetech P8F189
Kontron 986LCD-M/mITX
MSI MS7265 (not confirmed)

From IDF: Acoustic Optimization for Desktop Platforms

Internet News

Attendance at the Spring Intel Developers Forum last week resulted in many new contacts for SPCR. Among the most interesting were Intel engineers in a thermal / acoustic division who provided information about new R&D efforts in this area. One result is a White Paper, which was provided to SPCR for direct distribution to our readers: Acoustic Optimization for Desktop Platforms (2mb PDF).

This is probably not the first document from Intel to deal with PC acoustics, but it is the first we've seen in a long time. Much of it focuses on BTX platform advantages, but it touches on many aspects of acoustics measurement and analysis that is of relevance to anyone interested in low noise computing. Most fascinating to us is the research done on Acceptable Acoustic Levels, which involved both group psychoacoustic polling as well as ambient noise measurements in four countries. We are planning an in-depth look at this paper in the near future.

PSU Load Balance Critical in Dual-Vidcard Systems

Internet News

Dedicated SPCR readers know from our PSU Fundamentals and Power Distribution within Six PCs articles that modern PCs draw the vast majority of power from the 12V line of the power supply. What's less well known is that internal interactions in most power supplies impairs the capacity to deliver high power into 12V when the 5V and 3.3V lines are too lightly loaded. ExtremeTech has an interesting article illuminating this issue in both technical and practical aspects.

Zalman HD160 ePC case

Aside from the extreme TNN cases, this is Zalman's first and only more-or-less conventional case. The HD160 is described as "a case utilizing an ultimate design allowing optimum air flow for home theatre system and strengthened anti-vibration method." It looks promising; we're seeking a review sample, of course.

Mobile SATA HDD Roundup

Internet News

The Tech Report also ran a 2.5" Serial ATA hard drive round-up comparing a quartet of mobile drives -- that we've already reviewed individually over the last few months. Their acoustics analysis falls short of our standards, but the performance tests make for interesting reading. (There's not even a hint that you might consider one of these for desktop PC use.)

Another Turion 64 vs Pentium M comparison

Internet News

Yesterday, the Tech Report posted an article comparing the performance and power efficiency of the AMD Turion 64 ML44 (2.4GHz / 1mb cache - rated at 35W) and the Intel Pentium M 760 (2.13GHz / 2mb cache - rated at 27W) -- this time, in a desktop system. This comparison is of interest to any one who's interested in the coolest, lowest power dissipation desktop system. It's too bad that the closer matched Turion MT40 (2.0GHz / 1mb cache - rated at 25W) was not used instead. The price / performance analysis could also have been more fairly and comprehensively tackled.

Power Consumption of Modern Graphics Cards

Earlier in the month, X-bit Labs posted one of their massive power consumption analysis articles on no fewer than 21 current video cards, ranging from Jabba-like excess at 120W to acetic parsimony at 24W. With the first class of gaming cards, especially run in dual SLI or Crossfire mode, there can be only answer to their question, "Is Power Consumption A Problem?" Regardless, the article, "The Grand Clash for Watts" is well worth a read for anyone considering thermal and power management seriously.

More Quiet VGA Cooling News

Sytrin has released details of their KuFormula VF1 line of universal VGA coolers. The most interesting detail? Use your own 120mm fan, or use their blower-type fan for performance which is (according to them) competitive with the excellent Arctic Cooling Silencer.

The new Asus EN7800GT extends the company's heatpiped, pivoted passive heatsink technology to a higher performance vidcard, as reviewed by Trusted Reviews.

Silent News, Dec 22/05

Quiet HDD: Seagate 7200.9 drives have been reviewed at The Tech Report. The good news for silent PC aficionados: The 160BG single-platter model boasts the lowest sound output of any drive the Tech Report has ever tested. (Note: SPCR has a review of some single-platter drives in the works, including this one.)

Fan Control: The T-Balancer's baby brother, the miniNG, has hit the streets, and's test bench. With only 2 fan/pump headers, this could be a useful alternative to the T-Balancer, as long as the rather primitive interface doesn't overshadow the excellent feature set.

Solid-state Storage: During HKEPC’s Techday 2005, Giga-byte launched the second revision of their successful RAM-based storage solution, the i-RAM 2. Whereas the first version used DDR1 and ran off a SATA I connection, the i-RAM 2 sports DDR2 memory, twice the DIMM slots for a total capacity of 16 GB, and uses a SATA II connection.. According to news site VR-Zone , you can even connect it to an external SATA connection (eSATA) or put it in a 5.25” bay for convenience.
