LGA2011 CPU Cooler Review Roundup
Xigmatek Gaia
A challenger appears!
Sometimes when we use the Hyper 212 Plus in a build we get comments to the effect of, “Why don’t you use Xigmatek’s Gaia? It’s just as good and just as cheap!” Just as cheap? Definitely. Just as good? We’ll see!
Stop us if you’ve heard this before: The Gaia is a skyscraper-style stack of aluminum cooling fins on top of three direct-contact copper heat pipes. The Gaia is 6.5 inches high by 2.9 inches thick (with the fan) and 4.9 inches wide. At one pound, 4.7 ounces, it’s practically the same weight as the Hyper 212 Evo. Aside from the slightly narrower cooling fins and the fact that it has three heat pipes rather than four, and its 12cm PWM fan is held on by rubber pegs rather than a plastic clip, the Gaia looks a lot like the Evo.
On LGA2011, the Gaia’s install process is pretty easy. Four double-sided thumbscrews screw into the universal backplate, a mounting plate screws onto either side of the heatsink and mounts onto those thumbscrews, and then four nuts secure the mounting bracket. There are no screws or any other way of putting pressure on the heat exchanger other than tightening the mounting nuts as far as possible. The rubber fan mounts pop into slots cut into the sides of the cooling fins, which is great for damping vibrations but not as easy to attach or remove as plastic or wire clips.

We just realized that the Xigmatek Gaia’s cooling fins resemble the letter X.
The Xigmatek Gaia cooled our overclocked i7-3960X to 75.7 C in our burn test, within two degrees Celsius of the Hyper 212 Evo. We still prefer the Evo’s installation procedure, at least for LGA2011, and don’t mind the $5 price premium, but the Gaia is nearly as good as the Hyper 212 Evo, and even less expensive.

Almost as good as the Evo; even cheaper.
Annoying fan mounts; cooler mount doesn’t apply much pressure

NZXT Havik 120
NZXT’s second air cooler, and they still can’t spell ‘havoc’
NZXT didn't enter the CPU cooling game until quite recently. We reviewed its first cooler, the skyscraper Havik 140, in December 2011. The Havik 140’s dual 14cm fans helped it power to the top of our air-cooling charts, though the slightly cheap-feeling mounting bracket kept it from Kick Ass Award status. NZXT’s second air cooler is the smaller, less expensive Havik 120.

The NZXT Havik 120 isn’t even close to the largest cooler in our roundup.
The Havik 120 stands 6.4 inches tall, 4.5 inches deep, and 5 inches wide with both 12cm fans strapped on—just about a quarter of an inch shallower and narrower than the 140. The Havik weighs more than two pounds, and has four fat heat pipes to the 140’s six. The Havik 120’s mounting mechanism uses the bars-and-crossbeam model from the 140, and installation is easy. The cooler’s two 13-bladed, 12cm fans have 3-pin connectors, and connect to one of two Y-splitters (one with a speed-limiting resistor). The fans attach to the cooling fins with rubber straps, which is not the most convenient mounting mechanism, especially when the motherboard is already mounted in the case.
The Havik 120 performed second-best of the five air coolers we tested, dropping the overclocked i7-3960X to 73.7 C at full burn. Using the included resistor splitter cable increased CPU temperatures by a few degrees but reduced noise to quite low levels.
We like that the Havik 120’s fin stack is high enough so the fans don’t interfere with most RAM DIMMs, and that it performs well without being too loud. It’s neither as quiet nor as effective as the 140, but it’s smaller. At $55, it’s a good midpoint between the $30 coolers in our roundup and those in the $80-100 range.

Good performance; two stock fans; easy install.
Rubber fan attachments can be tricky; fans can get loud at full blast.
