Silent PC Review is dedicated to reviews, news and information about acoustics of computers and components, as well as their energy efficiency and thermal performance.

Antec NeoPower 480 PSU

Power
Antec has named a new power supply after pop cinema culture's most recent futuristic savior icon. The Antec NeoPower 480 is the first retail PSU with detachable, customizable peripheral output cables. Very nifty! It is also Antec's first 120mm fan model, with Active PFC and ATX12V V2.0 compliance for PCI Express. You can't help ask, Is it The One?

Yeong Yang "Mars" YY-5603 mid-tower case

Cases|Damping
Yeong Yang's new MarsYY-5603 mid-tower case is a Thermally-Advantaged Chassis designed for hot systems. It happens to have many strengths that make it suitable for quiet computing. The intelligent bezel design, the very good airflow potential, the sturdiness of the case, the attention to small details: All these add up to a serious case, one with some very nice user-friendly features that many silent PC enthusiasts will willingly adapt. Click here for SPCR's detailed review of the Yeong Yang Mars YY-5603.

SilverStone SST-LC01 HTPC Case

Cases|Damping
SilverStone's SST-LC01 is a high quality, generous size, aluminum HTPC case with good overall design that's actually pretty good for a quiet computing platform. It also happens to be an excellent prospect if you wish to modify a case for extreme silent performance. In essence, a clever adaptation of a small mid-tower into a HTPC case.

Coolmax Taurus CF-300 Fanless ATX PSU

Power
The Coolmax Taurus CF-300 is the second fanless ATX power supply to be reviewed by SPCR. Fanless cooling is the ultimate goal for those who pursue silent computing, and the Coolmax Taurus is one of the many new components that boast fanless operation. It is quiet and hihgly efficient but runs hot, and the review sample had a small malfunction. Nonetheless, a product worthy of consideration and a nice option for those who run cooler components in cooler climes.

OCZ Power Stream 470

Power
OCZ leaps into the PSU market with their new Power Stream series, which boast high power (420, 470 and 520W), low speed dual fan push-pull cooling, user adjustable voltage lines, EPS12V and SATA compatibility, and much bling in the form of mirrored chrome finish and LED fans. Is it suitable for high power quiet computing? We review the OCZ Power Stream OCZ470ADJ to bring you the full details.

Scythe Samurai SCSM-1000 CPU Cooler

Cooling
Scythe continues its tradition of unusual and effective cooling products with their new Samurai SCSM-1000, an all-platform (socket A, 478 & 754) CPU cooler that combines all-copper construction, a fan with an integrated speed controller, and superior performance with the fan blowing up rather than down. SPCR's Ralf Hutter likes it.

Cool-n-Quiet Athlon 64 Motherboards

CPUs|Motherboards
AMD's Cool 'n' Quiet for Athlon 64 reduces the working frequency and Vcore for reduce power consumption and heat when the processor is not under heavy load. Combined with an intelligent thermal fan setup, CnQ can be an easy way to make a quiet, very powerful PC. Unfortunately, only some Socket 754 and Socket 939 boards have CnQ support. Information about CnQ boards is spotty, and even AMD does not appear to have a comprehensive list. Here's a start to SPCR's own CnQ motherboards database in the Recommended section, with data compiled by Joachim Kluge.

Fanless DIY Dual-P3 WC System

Do-It-Yourself Systems
Given the the absence of any decoupling suspension on the hard drive, Ami's fanless dual-CPU P3-500 Blue 42 can't be a silent system. But I think it must be very quiet and it must have been fun for Ami Rodan to build. It's another testament to PC silencing creativity — although some will quibble over the mixing of metals in the watercooling system.

Getting Ready for BTX

PCStats looks at the BTX form factor and early boards on display at the recent Computex show in Taiwan. Intel's 775 CPU, and 915 / 925 chipsets are featured in almost all the prototype boards but none are available for sale to consumers.

Athlon 64 for Quiet Power

CPUs|Motherboards
Athlon 64 for Quiet Power is a detailed discussion of the AMD Athlon 64 Processor as it pertains to silent computing by Bryan Cassell, a new contributor to SPCR. Close attention is paid to AMD's and Intel's divergent definitions of Thermal Design Power, and the likely actual maximum power dissipation of these CPUs.

15 Multi-Fan Controllers reviewed at Tom's

Fighting Fan Noise Pollution is Tom's Hardware Guide's massive review of 15 multi-fan front panel controllers. They fail 2/3 of the units for not having a good high temp or fan fail alarm, but do list the fan voltage range of each controller (critical for SPCR) -- and other features. No time is spent on whether the controllers cause PWM noise in the fans or buzz themselves when fan voltage is reduced, both of which are not uncommon problems.

New Stock Intel Prescott P4 Cooler

Cooling
It could be what's standard on Prescott P4s these days, and it's somewhat quieter than the "high-end" copper base version we examined in January, but this HSF definitely does not cool as well. Seem odd for Intel to step backwards in cooling power while increasing CPU heat... Here's our review of the new

CoolerMaster Hyper 6 Heatsink for P4/K8

Cooling
The CoolerMaster Hyper 6 is the biggest and heaviest heatsink yet reviewed by SPCR. It is capable of a new level of quiet cooling performance substantially better than we've ever seen before. The design is advanced and clever yet not without flaws. Another lay-it-bare heatsink review brings you the Good, the Bad and the Ugly of the cross-platform Hyper 6.

Seasonic Super Series Revisited - Rev. A3

Power
The latest A3 Revision of the Super Series is Seasonic's attempt to fix intermittent fan controller problems that have dogged the previous revisions of these PSUs. Last week I received a package of four Rev. 03 Super series samples: One each of Super Tornado 300 and 400, and Super Silencer 300 and 400. Our revisit shows that not only has the fan controller been fixed, Seasonic also managed to make big improvements that might even justify the launch of a new line.

Spire Coolwave SP441B0-F HSF review

Cooling
Spire claims their value-oriented Coolwave SP441B0-F heatsink cools even Prescott P4-3.4 and does it quietly. An all copper, low-profile heatsink and an integrated 70mm fan with speed control: Ralf Hutter tells us how it fares.
