LGA2011 CPU Cooler Review Roundup
Intel’s enthusiast platform puts out the heat—here are seven ways to take it off

Intel’s Sandy Bridge-E enthusiast platform brings with it a new Intel socket, and that means new cooler mounting brackets! One nice thing about the X79 chipset: The boards ship with an integrated universal CPU mounting backplate, so no more fiddling around behind the motherboard.
Now, the new chipset hasn't been out that long, so cooler manufacturers are still working on getting their products compatible with the universal backplate. We were able to wrangle up seven LGA2011-compatible CPU coolers, ranging in price from $30 to $120, to see how they cope with the new mounting system and whether they’re up to the task of cooling an overclocked Sandy Bridge-E CPU.
We tested each cooler on a test bed with an Asus P9X79 Deluxe motherboard, a i7-3960X CPU, 16GB of DDR3, and a Thermaltake Level 10 GT case with its stock fans running at “high.” The i7-3960X is the flagship Sandy Bridge-E CPU, and contains six cores and support for 40 PCIe lanes. Its Turbo mode hits 3.9GHz out of the box, but we’ve clocked the proc up to 4.2GHz. We tested each cooler after an hour of idling and an hour of full burn at 4.2GHz, using the Sandy Bridge-E version of Intel’s internal thermal testing utility, and measuring the core temperatures with HWMonitor. To further level the playing field, we’re using the same thermal interface material for each cooler, eschewing the included thermal pastes in favor of Arctic Silver’s Lumiere, which we’ve used for all our cooler tests for years. In a sidebar, we’ll also talk about the effect of thermal paste on CPU performance.
Because very few of us run our CPUs at 100 percent across all cores for long stretches of time, the burn temperatures represent worst-case scenarios—this should be the hottest these CPUs ever get.
Cooler Master Hyper 212 Evo
Meet the new boss, same as the old boss
What, this old thing? Cooler Master’s Hyper 212 Evo is the new‑and‑improved version of our standby CPU cooler. It’s just $35 and offers performance far exceeding other coolers in its price range, so it’s the first thing we reach for when we build a new budget-conscious rig. Given that LGA2011 CPUs don’t come with heatsinks, the Evo is the closest thing we have to a stock cooler, and it will be the standard against which all other Sandy Bridge-E coolers are judged.

The plastic fan clips on the Evo are much easier to use than the wire clips that originally came with the first Hyper 212-Plus.
When we reviewed the Hyper 212 Evo in the January 2012 issue of our magazine, we had two major complaints about it: The backplate mounting procedure remained annoying, and the cooler didn’t have LGA2011 mounting support. Both of those problems have now been addressed.
The Hyper 212 Evo is a skyscraper-style heatsink, with four direct-contact copper heat pipes rising into an array of aluminum heat-dissipation fins. From the base of the heat exchanger to the tips of the heat pipes, the cooler is 6.3 inches tall, 3.13 inches deep, and 4.7 inches wide with the included 12cm PWM fan attached.
Thanks to the unified backplate on the LGA2011 socket (a crossover from Intel’s Xeon platforms), the Evo’s mounting process is greatly simplified. The LGA2011 X-shaped crossbar now screws directly into the mounting holes on the included backplate. No more accidentally unscrewing mounting bolts when removing the cooler.
In our test bed, the Evo continues to impress, cooling our i7-3960X at 4.2GHz down to 74 C. It’s not the best cooler in this roundup, but it outperforms coolers three times its price. And although its height may be a concern in narrow cases, the heatsink and fan do not interfere with any RAM slots, unlike many other coolers in this roundup. The Evo remains an inexpensive, inexplicably kick-ass cooler.
