OCZ Power Stream 470

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

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

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

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

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

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

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

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.

Deep UnderVolt/Clock: 4.7W CPU PC

Do-It-Yourself Systems
A reader's account of the most extreme undervolted and underclocked system I've yet heard about. Mark Charlesworth created an auto-speed adjusting AMD XP1700+ system that runs with as little as 4.7W CPU power draw yet ramps up to full speed when needed. Read how he did it!

Avance Terminator case: Thermally Advanced?

Among the thousands of products being show at Computex in Taipei this week, news of the Terminator case (model C001) from Avance caught my eye. It seems to be a thermally well-optimized case with much promise for PC silencers. Here are some pics, courtesy of a TweakTown news blurb. (Click photos to enlarge.)

Like the recent Lian-Li V-series cases, there are separate thermal zones, and the mainboard is mounted upside down. There are two 120mm fan vents, one low on the front panel and the other low on the back panel. A cooling duct joins the two vents, blowing outside air across the CPU/Cooler that's in the duct path and exhaust the heat out. A chamber between the PSU and the mainboard compartments accomodates HDDs. The only issue is where the heat from a hot VGA card will go.

A review sample has been requested.

A Reader's Report: Lian-Li PC-V2000 Tower Case

Reader Charles Gilliatt's write-up on the big version of Lian-Li's new PC-V series of cases that turns the AXT tower configuration upside down with the PSU on the bottom. It's visually stunning, and Charles gives us lots of photos to ogle along with a detailed description of his impressions on his first step towards PC silence.

VoodooPC Rage F-50 PC / Zalman TNN-500A Case

Complete|Mobile Systems
When a gaming computer specialist teams with a quiet component leader, you expect the end result to be... the VoodooPC Rage F-50, which wraps a Zalman Fanless TNN-500A case/psu/cooling system around an Athlon A64, ATI9800XT, RAID drives and gobs of fast RAM. Our review of the F-50 System... and the fanless Zalman TNN-500A: It is impossible to write about the former without also discussing the latter.
