Gigabyte GA-Z77X-UD5H

Of all the boards here, we’re most intimately familiar with Gigabyte’s GA-Z77X-UD5H. It’s the board we used for the bulk of our Core i7-3770K testing, and one thing we can say, it’s stable. We’ve literally run more than 50 hours of benchmarks on this board without any issue.

We hit our highest auto-overclock with the Gigabyte GA-Z77X-UD5H.

Vertical vapor chamber—blowing hot air?

WE  HAVE BEEN anxious to test Cooler Master’s TPC 812 since we saw a prototype at this year’s CES—or was it last year’s? Regardless, the company piqued our interest with its talk of “vertical vapor chamber cooling,” and we finally have our hands on the TPC 812, a massive air cooler with six heat pipes and two vertical vapor chambers.

Double your radiator space, double your fun

ANOTHER ALL-IN-ONE liquid-cooling loop! Hooray! Corsair’s H100 is its fifth liquid cooler; after two with Asetek, the company has put out three with CoolIT. The H60 is your standard 120mm radiator-with-single-fan, the H80 is the double-thick double-fan version, and the H100, the first Corsair liquid-cooler to support LGA2011, is its first cooler with a 240mm radiator.

The H100’s radiator is around an inch thick and 10.8 inches long and fits in any case that can accommodate a 240mm radiator, though some cases may not have the vertical clearance to mount the fans inside the case. The pump/heat exchange unit is square, and very slightly taller than Asetek’s. It contains four 4-pin PWM headers to control the radiator fans, as well as a connector for Corsair’s Link system control software/hardware combo (sold separately). There’s also a three-speed fan-control button on top of the pump. The pump unit itself has a 3-pin motherboard fan connector and a 2-pin Molex for power. The cooler unit mount is simple; four double-sided thumbscrews mount to the unified backplate, the brackets at the corners of the pump unit slide onto those, and more thumbscrews secure them in place.

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.
