Tesla H for a Fanless NUC

Cases|Damping | Cooling
Tesla H is one of a dozen fanless "heatsink" cases offered by Akasa. This one is for the Haswell NUC and can house two 2.5" drives in a wider, sleeker design. Thermally, it's a winner, too. Market pricing vis a vis NUC kits and boards is its real challenge.

Noctua NH-D15: Update to an Icon

Cooling
The iconic Noctua NH-D14 helped usher in a new area of gigantic dual fan heatsinks. Its successor, the D15, is slightly heavier and larger, features upgraded matching 14/15 cm fans, and more densely packed fins.

Scythe Kotetsu CPU Cooler: A Compact King

Cooling
Weighing just over a pound and having only a single 120 mm fan, the Scythe Kotetsu still manages to compete and beat much of the larger competition.

be quiet! Shadow Rock Slim CPU Cooler

Cooling
A slim tower cooler built in the same vein as the Noctua NH-U14S, the bequiet! Shadow Rock Slim is lighter, more affordable, and surprisingly proficient.

Thermalright HR-22 CPU Heatsink

Cooling
The Thermalright HR-22 is a substantially bulked up version of the HR-02, weighing in at 1.17 kg. A plastic air duct is included to create a quasi-passive cooling solution. Is it worth a C note?

Our Lapped CPU Heatsink Test Platform

Cooling | Reference|Recommended
Lapping the CPU in a heatsink test platform is probably a controversial move that's bound to provoke reactions. Funny thing is, it was done a year ago, and photos of the CPU showing the copper top exposed by the lapping have been featured in many of our reviews. Yet, not a single comment. This article goes through the problems, investigations and explorations that led us to lap our Core i7-965 Extreme test CPU, and analyzes the results and implications.

Noctua NH-U14S Slim 140mm Tower Cooler

Cooling
The NH-U14S is a lean and mean CPU cooler in the distinctive Noctua style, with a slender physique to help avoid memory interference while still packing a surprisingly heavy punch.

Scythe Ashura CPU Cooler

Cooling
Built in the same vein as the successful Mugen 4, the Scythe Ashura features a slimmer, asymmetrical body, and a larger 140mm Glide Stream fan.

SilverStone Tundra TD03 Liquid CPU Cooler

Cooling
The SilverStone Tundra TD03 self-contained CPU water cooler uses a different radiator and water block design than its competitors in an attempt to improve its efficiency.

Scythe Mugen 4 CPU Cooler: Scythe Strikes Back

Cooling
The Mugen 4 is the first truly elite Scythe heatsink we've tested in many years. An updated mounting system and an acoustically sound fan help gives it an edge against some its bigger, more expensive rivals.

SilverStone Argon AR02 CPU Cooler

Cooling
Though smaller and lacking the high tech fan of its big brothers, the SilverStone Argon AR02 still delivers a powerful punch for its size and weight. A good choice for smaller (though not tiny) cases.

NoFan CR-95C Copper Fanless CPU Cooler

Cooling
A massive cylindrical heatsink, the fanless (and thus noiseless) NoFan CR-95C Copper actually cools processors with power envelopes up to 95W. This is unprecedented.

SilverStone Argon AR01 & AR03 CPU Coolers

Cooling
A solid mounting system helps the SilverStone Argon AR01 and AR03 direct-touch heatpipe coolers reach elite status among SPCR tested CPU heatsinks.

Noctua NH-U12S Slim Tower Heatsink

Cooling
The NH-U12S is an attempt by Noctua to take everything we like about the larger NH-U12P and cram it into a slimmed down form factor for improve compatibility.

Cooler Master Seidon 240M: Dual Fan Liquid CPU Cooler

Cooling
The Cooler Master Seidon 240M is a self-contained liquid CPU cooler with a dual fan radiator. Though equipped with a very quiet pump, its low noise performance doesn't justify the US$100 price when compared to top air coolers.
