T-bred/Barton unlocking for easier under/overclocking

Lost Circuits has an article on an easy way to unlock the multipliers of a AMD Athlon Thoroughbred or Barton. While multiplier unlocking is a common trick to overclock a CPU, it can be equally applied to underclocking for lower temperatures and easier silencing.

High Performance Heatsink Reviews

New flagship heatsinks Thermalright SLK-900-U and Zalman CNPS-7000, already hot topics in the the SPCR forums, are beginning to get review coverage. Can they allow even slower, quieter fans than silent pc'ers are currently using?

SilentDrive reviewed at bit-tech

The SilentDrive, a hard drive silencing product known to overheat 7200 rpm drives, is reviewed by the folks at bit-tech. They give the SilentDrive a good review, but MikeC's first-hand experience (see SPCR's Recommended Hard Drives section) shows that this product is surpassed by others.

AcoustiPack Noise Damping Kit

The review compares the noise from a AcoustiPack-treated Antec Sonata case versus a "bare" Sonata. Goes on and on... but lots of interesting things in there -- other damping materials, what the stuff should do, and high quality MP3s for comparisons. A bonus for the uninitiated: One is of the Panaflo 80L at 12V at 1 ft.

PC World features SPCR... & MikeC

Kanie Hedgehog + EPIA M9000 Mod

Bo hacked a massive Kanie Hedgehog copper HS for P3 and mounted it on a VIA EPIA M9000 (933 MHz) but found he still could not run it without a fan. At least not in a low fan speed modded-PSU Chyang Fun E-Note case. His DIY piece at mini-itx is definitely worth a read.

Intel's Quiet PC Tips

The Silent Front
Late but still interesting follow-up on Intel's Quiet PC R&D, covering thermal control issues in new SFF PCs as well as controlling and reducing computer noise. Includes a look at ther new fan design, which may already be in production in their latest high-end P4 heasinks.

Intel's Chips are Down

"PC game wiz Johnathan Wendel knows what's wrong with Intel. It needs to shift focus away from chip performance and set its sights on lower costs." -- This is a very appropos, insightful, big picture analysis of where the PC industry is headed and why: An editorial in the (Canadian) National Post by Wynn Quon, CTO at Legado Assoc. Well worth a read! These trends will affect you and me.

Undervoltable Motherboards

A new page called Undervoltable Motherboards has been added to the Recommended Section. The reason is simple: this info is hard to come by, and undervolting is very useful in reducing CPU heat, which can lower cooling requirements. This means lower fan speeds -- and less noise. Check your motherboard; if it is undervoltable, please add it to the list!

The State of Computer Noise: January 2003

The Silent Front
It's amazing to look back and see that it's been three quarters of a year since the launch of Silent PC Review. Time flies when you're having fun - and busy beyond belief! As it is the beginning of a new year, it seems appropriate to review the State of Computing Noise in Jan 2003: An overview, a challenge and a promise.

Laptops cool off with 'smart' heat pipes is running an article that talks about recent refinements to heat pipe technology that should allow for smaller, more effective heat pipes that could lead to smaller and more efficient notebook computers.

More on VIA Nehemiah C3 processor

More good news: The Nehemiah C3 is Tualatin and pre Tualatin mobo compatible! This means it's harder to miss with most boards, and selection is bigger than before. The most up-to-date motherboards can be used.

Rubber Boxes & Carved Foam: More HDD Silencing

Two more HDD silencing techniques for DIY: LeoQ's Rubber Box for obnoxiously noisy drives and MikeC's Carved Foam decoupled mounting for the Barracdua and other quiet drives that still vibrate. May be worth a read even if you're not a DIYer.
