Arctic Cooling Freezer 4 heatsink/fan

Cooling
The Freezer is Arctic Cooling's "high-end" heatsink. At US$34 it is still relatively inexpensive, but is targeted at the performance market. Can this modest heatpiped HSF compete successfully in cooling performance while maintaining AC's reputation for low noise established with their Super Silent series?

Silently Cooling the Pentium M Desktop Platforms

Cooling
It is a tome about the merits of the Pentium M 2.0 Dothan with 855-chipset desktop boards by AOpen and DFI for silent, powerful computing. We\'ve waited 18 months for these boards and our Pentium M desktop platform review was two months in the testing and writing. ...

Arctic Cooling Super Silent 4 Ultra TC heatsink/fan

Cooling
Arctic Cooling updates an old budget favorite, a deceptively simple aluminum extrusion heatsink with a frameless 92mm fan that features thermal fan speed control. It's not a giant killer, but it is very quiet, really easy to install and provides perfectly adequate cooling performance -- all for US$20. The 4 Ultra TC HSF show that the miserly, efficiency obsessed engineers at AC are still on their game.

Zalman CNPS7700-AlCu Heatsink/Fan

Cooling
The new Zalman 7700 heatsink/fan is a natural extension of the radial design of the successful 7000 series to the higher thermal demands of the most recent processors — particularly the fastest Intel Prescott core P4s with their >100W output. An integrated 120mm diameter fan is employed instead of a 92mm fan. How does the biggest and best from Zalman compare against its precessors, and against the Thermalright XP-120 with a 120mm fan of one's choice?

Thermaltake CL-P0025 Silent Tower CPU heatsink/fan

Cooling
After two and a half years of heatsink reviews, we finally tackle one from the most prolific of aftermarket CPU cooler brands. Thermaltake's Silent Tower is one of the new breed of tall heatpipe-equipped designs with fan airflow that goes across the board rather than down or up. They've incorporated some nice design features and a couple of real muffs. Are the snafus fatal?

Chaintech AA6800GT + Arctic Cooling NV Silencer 5

Cooling
The NV Silencer 5 faces the challenge of taming a hot Chaintech AA6800GT Apogee gaming video card in our look at a second new video card cooler from Arctic Cooling. Is it up to the cooling challenge? And does it achieve cool quietly? We share our findings in a dual product review.

Arctic Cooling ATI Silencer 2 VGA cooler

Cooling
Since our review of the original VGA Silencer a year ago, Arctic Cooling wised up to the demand for similarly quiet cooling for all kinds of VGA cards, not just selected ATI cards. Hence the recent release of their second generation of video card coolers, called ATI or NV Silencers, eight models in all to cover almost all the current cards from the two VGA giants. A close look and listen of the ATI Silencer 2 installed on a Sapphire 9600XT.

CoolerMaster Hyper 48 HSF: 478, K8, 775

Cooling
Yet another new high-end HSF from CoolerMaster loudly claiming "Ultra Silent" status, the Hyper 48 is large, all-copper, heatpipe equipped, comes with an integrated 92mm fan and with mounting hardware for sockets 478, K8 and 775. How does it fare in SPCR's thermal, acoustic and airflow testing chamber?

Thermalright XP-90 CPU Heatsink

Cooling
Thermalright's XP-90 CPU heatsink, which features four heatpipes, thin aluminum fins and a nickel-plated copper base, was released at the same time as the XP-120. It is essentially an XP-120 shrunk to work with a 92mm fan for those who cannot accommodate a 120mm fan. Amazingly light, a little cheaper, and much easier to install: How does it perform with a quiet fan like the Nexus 92? SPCR puts the XP-90 through its paces and brings you the full monty, complete with high resolution sound files.

Review: CoolerMaster Ultra Vortex HSF

Cooling
The Ultra Vortex is a recent addition to CoolerMaster's enthusiast HSF line, one that addresses the quiet market -- at least in the promotional material and packaging. It is also one of an increasing number of cross-platform HSF. This one works for socket 478 and the AMD K8 sockets. An all copper radial heatsink with thin fins and a 92mm fan: Reminiscent of a Zalman 7000, isn't it? How does it compare? The Ultra Vortex review, complete with MP3 sound files that you can listen to and judge for yourself.

Calibrate Your CPU Temp Reporting

Cooling
Intelligent thermal management is the key to silent computing, but CPU temperature reporting mechanisms in current processors and motherboards are inaccurate, with results that can vary by 10°C or more. The causes of the inaccuracies are complex, but correcting them to a more reasonable margin of error is not terribly difficult. Russ shows you how.

Nexus PFT-3600 P4 Cooler

Cooling
The PFT-3600 is a P4 Cooler with a 70mm fan skivved from a single piece of aluminum. Compact, light and easy to install, it is from Nexus, one of quiet computing's few truly well-established brands. Read the Nexus PFT-3600 review here.

Scythe NCU-2000 Fanless CPU Cooler

Cooling
Scythe continues its tradition of unusual innovation in silent computing components. The NCU-2000 is an update of a HS designed to run completely fanless. This huge model uses flat heatpipes, widely spaced thin fins and a copper base that can rotate so the fins are correctly oriented regardless of CPU socket orientation on socket 478 or A64. Yet it's just 505 grams, a hundred grams lighter than the original NCU-1000; is it better?

Thermalright XP-120: 1st 120mm fan CPU heatsink

Cooling
With Intel CPUs far exceeding the 100W mark, you knew it was going to come to this, sooner or later: A massive heatsink designed to work with a 120mm fan for a new level of cooling. Thermalright is the first out of the gate with their XP120. Thin aluminum fins, a very large radiant surface, copper base and heatpipes. Simply put: Its performance sweeps aside every other HS.

CoolerMaster Vortex Dream Heatsink/Fan

Cooling
The CoolerMaster Vortex Dream is a new heatsink/fan by that offers many high-end features at a budget US$22 MRSP. All-copper one-piece skivved design, cross-platform (P4/A64) compatibility, and an integrated 70mm fan with built-in manual speed control. It's a lot for the money. We hustled the Vortex Dream to the SPCR heatsink torture test chamber to bring you the real goods.
