Intel RTS2011LC Review

Underwhelming in the extreme

Intel isn’t shipping stock heatsinks with Sandy Bridge-E CPUs, perhaps assuming that consumers of $600 and $1,000 CPUs are going to want performance a little better than Intel’s stock coolers have typically provided. Instead, Intel is offering a branded liquid-cooling loop as an optional accessory. The Asetek-built cooling loop features a glowing blue Intel logo and a bright blue LED on its single 12cm fan, but otherwise looks nearly identical to the Antec Kuhler 620, which was also built by Asetek (which also built AMD’s Bulldozer-branded liquid cooling loop).

Zalman CNPS12X Review

The latest Zalman heatsink looks cooler than it is

THE CNPS12X MIGHT be Zalman’s most eye-catching cooler, with two arrays of black-nickel-coated cooling fins and three 12cm fans to push air through them. And it is massive. It’s 6.1 inches tall, 5.25 deep, and more than 6 inches wide, and weighs two pounds, four ounces. It’s so big it overhangs the inner four RAM slots on our Asus P9X79 Deluxe test motherboard, requiring the use of RAM without tall heat spreaders. The six direct-contact heat pipes rise into two sets of cooling fins, with the front and rear fans nestled into their respective fins, and the middle fan in between the two sets. All three fans are controlled via a single 3-pin power connector.

Noctua NH-D14 SE2011 Review

Cooling prowess as massive as its dual heatsinks.

WHEN WE REVIEWED the first-edition Noctua NH-D14 back in April 2010, we praised its quiet performance, but our then-current test bed didn’t put out enough heat to best showcase its cooling chops. Fortunately, our new one does. This coincides nicely with Noctua’s release of the NH-D14 SE2011, which includes (gasp) LGA2011 support and updates the D14’s two fans to include PWM, or pulse-width modulation.
