Review: ActiveCool AC4G Thermoelectric cooler

Cooling
With Intel CPUs soaring well over the 100W mark, questions about the efficacy of conventional heatsink and forced air cooling arise again. The AC4G system from ActiveCool employs one of the likely alternatives: Thermoelectric Cooling. Thermoelectric Coolers (TEC) are nothing new, but Active-Cool aims to put the technology to work in a new way, by varying the power of the TEC in accordance with demand to keep both the temps and the noise down. Our indepth-report on the ActiveCool AC4G.

Scythe's e-Otonashi fanless EPIA-M cooling case

Cases|Damping | Cooling
In the e-Otonashi, unusual heatsink maker Scythe has turned again to a Heatlane heatpipe, in a somewhat more ambitious product: A compact case for VIA EPIA-M Mini-ITX boards that offers a fanless CPU cooling system as an integral part of its design. In many ways, the e-Otonashi is a kind of poor man's do-it-yourself kit version of the recently reviewed Mappit A4F, a small, prebuilt fanless, EPIA-M PC. For those who prefer to cook their own rather than dine out... our review of Scythe's e-Otonashi fanless EPIA M case.

Review: Thermalright ALX-800 AlCu hybrid cooler

Cooling
The Thermalright ALX-800 is their first aluminum/copper hybird CPU cooler since their highly popular now discontinuedAX-7. It seems to be modeled on their successful SLK-800 copper cooler. Does the ALX-800 meet the high standard Thermalright have set for themselves?

Review: Intel's "High-End" P4 Cooler

Cooling
How does the copper-based heatsink/fan supplied with Intel's higher speed P4s compare against the aftermarket leaders like Thermalright, Swiftech and Zalman? Find out in our noise / cooling performance review of Intel's "high end" P4 cooler.

Review: Thermalright SP94, SP97 & other heavyweights

Cooling
It began as a Thermalright SP94 review but soon took on a life of its own and spiralled out of control into this sprawling heatsink roundup involving the SP97, SLK900, and Zalman 7000A (both cu and alcu versions) on Intel P4 as well as AMD Socket-A platforms. Who's the coolest of them all? Both P4 and socket-A test platforms get updates, as well.

Review: Swiftech MCX462-V for Socket A

Cooling
Russ tackles the MCX462-V, a clear continuation of classic Swiftech heatsink design: Thick copper base with helicoid aluminum pins press fitted into the base. But as with the MCX478-V, the P4 counterpart recently reviewed by Ralf Hutter, this Socket-A heatsink is designed "to optimize cooling at air flow levels as low as 22CFM and 23dbA." Our MCX462-V review shows you how well Swiftech has achieved its goal.

Review: Swiftech MCX478-V P4 Cooler

Cooling
It was not long ago that we reviewed a Swifty, yet here's another one, a new gen with a twist -- no, a bend! -- this time for the P4: The Swiftech MCX478-V. Ralf runs a gamut of tests with a variety of fans on the new heatsink, then tosses it in the ring with some recent heavyweight contenders for a thorough comparative roundup.

Review: Arctic Cooling VGA Silencer

Cooling
Two weeks ago, I jumped the gun to post a preview of the Arctic Cooling VGA Silencer because I did not have access to an ATI 9500-9800 or nVidia GF3 card, for which the product is designed. Russ Kinder happens to have a Sapphire-ATI 9500 VGA card, now nearly 2 years old, but still a good performer, and more importantly, one that the Arctic Cooling VGA Silencer would work with. I arranged to have a sample sent to Russ, and now, a scant week later, we've worked together to turn this once-preview into a full review.

Swiftech MCX462+ Heatsink Review

Cooling
Just one look and you know it's a Swiftech. A Swiftech MCX462+, to be precise. Russ tackles a review of this massive cooler from the original heavyweight CPU heatsink maker. A little late, as the replacement MCX462-V has already arrived... but that's not Russ's fault, and he's already looking at the new beast. Meanwhile, enjoy his MCX462+ review.

Scythe Heatlane Zen NCU-1000 fanless CPU cooler

Cooling
The Heatlane Zen NCU-1000 CPU Cooler is another unusual CPU cooler from Scythe. It is massive, looking for all the world like a skyscraper on the motherboard, it uses a heatpipe to spread the heat evenly throughout its substantial expanse, and it is designed to cool P4 processors while running completely fanless. SPCR takes them at face value and tests the Zen without a fan on a P4-2.53 system.

Review: Arctic Cooling Copper Silent 2 TC

Cooling
Thermally controlled fans on CPU heatsinks attempt to provide silence whenever possible, and maximum cooling ability when needed. It’s simple in concept, but very difficult to make work in practice. Arctic Cooling have been doing it for a while. Russ examines their latest iteration for socket-A, the Copper Silent 2 TC. It is a thumbs up for the SPCR audience.

Review: 3aCooler's Zebra AlCu1 heatsink

Cooling
The 3aCooler Zebra AlCu1 Socket-A heatsink borrows a little from Thermalright and a little from Zalman but ends up with its own compact, tidy approach to CPU cooling. Rusty's first HS review for SPCR on this interesting, mostly successful product from Romania is succinct and precise.

Review: Arctic Cooling Super Silent 4 Pro TC

Cooling
Another cooler reviewed for the hot summer, this time a brand new thermally controlled HSF for P4-478 from Arctic Cooling. Inexpensive and effective, fine attention to details, great for those seeking simplicity and not cutting-edge performance.

Review: Kamakaze HSF by Scythe

Cooling
The Kamakaze CPU heatsink by Scythe in Japan is an unusual product, offered as a complete package with 80mm fan and manual speed controller. With a strong resemblance to Alpha heatsinks, the Kamakaze seems to have been designed from the ground up for "native" compatibility as a socket-478 or socket-A/370 cooler. Read the review.

Review: Zalman 7000-Cu / AlCu CPU Heatsink

Cooling
An extensive review of the Zalman CNPS7000-Cu and -AlCu, the current top of Zalman's extensive P4 cooler line. They depart from the last generation of Zalman's top P4 coolers from by being radial rather than "fanned", and by having an integrated fan rather than one on an extended overhead bracket. How quiet and how cool?
