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

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

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?

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.

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
, 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.

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.

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.

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.
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.

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

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.

Thermally controlled fans on CPU heatsinks attempt to provide silence whenever possible, and maximum cooling ability when needed. Its 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.

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.

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.

The Kamakaze CPU heatsink
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.

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?
