Intel 980X: High-Output Fan

Overclockers are known for being particular to their equipment, which is why Benchmark Reviews changes our format with each new project. Although it's impossible to nail-down which cooling fan is the overwhelming choice for overclocker projects, most enthusiasts would agree that fans with the best static pressure and highest airflow are the most appropriate. Because of size and design constraints in most of these products, a 120x120x25mm fan is as large as we can go with our collection of CPU coolers. This section uses the high-output Yate Loon D12SH-12 cooling fan on each product tested. The D12SH-12 cooling fan forces an impressive 88 CFM of air at a moderately noisy 40 dBA, and performs better than several 120x120x38mm fans we've tested (more on that later). In my experience, the Yate Loon D12SH-12 is one of the best 120mm cooling fans available in regards to the noise to performance ratio.

Overclocked to 4.0Hz @ 1.375V, Benchmark Reviews tests our collection of heatsinks on the hexa-core Intel Core i7-980X Extreme Edition. While some enthusiasts may dare to trespass beyond this voltage, Benchmark Reviews needed our test system to remain functional long enough to complete testing on nearly twenty various products under several different conditions. Our readers must remember that every product must pass testing on the same motherboard and processor, and if one of these fail all the testing must be redone completely.

All of the top performing CPU coolers have a few things in common: bolt-through mounting clip systems that create impressive contact pressure. Although some mounting systems are better designed than others, The mounting system on the Prolimatech Megahalems and Armageddon heatsinks use a bolt-through system with slotted alloy plates to ensure a perfectly centered cooler, which was a good bit better than the Xigmatek Crossbow kits we use on compatible coolers. The new mounting kit that comes with the Thermalright Venomous-X heatsink creates a dangerous amount of contact pressure, although we were able to tighten the cooler all the way without incident. Thermalright's Ultra-120 eXtreme, Cogage TRUE Spirit, and Cogage Arrow all use a similar bolt-through kit that creates substantial contact pressure. At least half of our CPU cooler collection have very flat mirror-finished contact surfaces, whereas the other half use Heat-pipe Direct Touch (HDT) technology. Every single one of these coolers have either large-gauge heat-pipes, or several pairs of heat-pipe rods integrated into the base. In my opinion nearly every single product on this chart is an outstanding aftermarket cooler, but only a select few can be considered the very best!

Knowing that this would stir some controversy, many of these heatsinks were tested seven or more times each, with the highest and lowest results thrown out with the remainder averaged. Benchmark Reviews reveals the results of our Intel LGA1366 CPU-cooler performance tests using high-output cooling fans in the chart below:

Intel-LGA1366 CPU Cooler

Thermal Difference Advantage
ProlimaTech Megahalems 24.29°C over ambient -4°C
Thermalright Venomous-X 24.47°C over ambient -4°C
Scythe Mugen-2 SCMG-2000 26.03°C over ambient -3°C
Cogage Arrow 26.53°C over ambient -3°C
Titan FENRIR TTC-NK85TZ 27.92°C over ambient -1°C
Zalman CNPS10X-Performa 28.08°C over ambient -1°C
Coolink Corator-DS 28.38°C over ambient -1°C
Cogage TRUE Spirit 28.39°C over ambient -1°C
Noctual NH-D14 (2x 140) 29.10°C over ambient
ProlimaTech Armageddon 29.26°C over ambient
Thermalright Ultra-120 eXtreme 29.40°C over ambient
CyberPowerPC XtremeGear HP-1216B 29.42°C over ambient
3R-System IceAge Prima Boss-II IA-120B2 29.46°C over ambient
Tuniq Tower-120 Extreme 29.52°C over ambient
Intel DBX-B ATS (Performance) 29.65°C over ambient
Xigmatek Balder SD1283 CAC-SXHH3-U06 30.00°C over ambient +1°C
Xigmatek Thor's Hammer S126384 30.76°C over ambient +1°C
Noctua NH-U12P 31.68°C over ambient +2°C
Thermaltake Contac-29 CLP0568 32.60°C over ambient +3°C

When a heatsink costs $65, it had better be real good... and thankfully the ProlimaTech Megahalems is. Cooling to a temperature of only 24.29°C over ambient, the Megahalems has only one competitor with close reach: the $70 Thermalright Venomous-X heatsink with 24.47°C. Both heatsinks come with polished base and outstanding bolt-through mounting system, and neither forces you to use an under-powered stock fan, so take your pick!

Proving (to me, at least) that our Benchmark Reviews Editors Choice Award was hard-earned, the Scythe Mugen-2 produces 26.03°C at the entry-level price of $35. If you're not after any overclocking records, and you don't mind the giant hassle for installation, this could easily be the best value of the bunch. The equally-large Cogage Arrow delivers a similar 26.53°C. Titan's FINRIR cooler produces 27.92°C, which nearly identical to the Zalman CNPS10X-Performa, Coolink Corator-DS, and Cogage TRUE Spirit.

Equipped with two large Xigmatek 140x140x25mm XLF-F1453 fans on an even larger heatsink, the Noctual NH-D14 finds itself midway through our results with 29.10°C. Equally large, and equally-equipped with the same two 140mm Xigmatek cooling fans, the ProlimaTech Armageddon cools to 29.38°C without a peep. Perhaps it's the two extra cores on Gulftown, or the less-than-stellar mounting kit, but the Thermalright Ultra-120 eXtreme falls down a few spots and rubs elbows with a $22 XtremeGear HP-1216B; which delivered 29.42°C and also matched the more expensive 3R-System IceAge Prima Boss-II. At 29.52°C over ambient, the massive Tuniq Tower-120 Extreme offered respectable performance, but the $64.99 price tag is a little too far off from fair market value.

For the first time in our testing, an Intel cooler has finished with top-level results. Set to 'Performance' fan speed, the Intel DBX-B Advanced Thermal Solution produced a notable 29.65°C over ambient temperature, which comes just barely ahead of the premium Xigmatek Balder SD1283 and Xigmatek Thor's Hammer S126384 heatsinks. The Noctua NH-U12P may be listed nearly the bottom of our chart, but 31.68°C is only five degrees from the top! To that same extent, the budget-priced Thermaltake Contac-29 finished our tests with 32.60°C.

In your reviews especially with the new Armegeeden cpu cooler I need to know if the height from where it is mounted .Will it clear my
tall denominated style memory ? this is a Big problem for many
thank you Paul.

Hello Paul:
It's not possible to include this information in every article, because every system is different and memory comes in many different sizes. I can tell you that if you mount this heatsink so it blows air towards the back of the case, you won't come close to the memory.

# Are Fan/s requiredTmemphis 2012-05-06 15:13
Some of the reviews show this without fans mounted. Does this require fans if you are going to run a 2011 LGA CPU at stock speed and not overclock?

I have a Home server Windows 7 in a smail case under my TV. I purchased a ASRock Gen4 X79 and an i7-3920 only to find no fan. Crazy!

I have little idea of these Coolers and their issues with Ram fitting in (or not fitting) and case size seem to be an issue not to mention height. I'm confused on what get. The intel cooler/fan you can buy seperate ($32) runs very hot for a standard and would cook the system in summer. What a mess intel have created.

On the bright side you seem to have the best cooler and I'm glad i found you guys. I wish it was more simple thou. Thank you

An X79 system seems like huge overkill for a home server, but that's what you have, so...

The Armageddon is a very tall cooler and I suspect you'd have problems fitting it in a small HTPC case. Also, these cases are designed for low-power components and typically do not have the airflow of a larger desktop case, so unless there's a fan pointed right at the heat sink I think running it without a fan would be a bad idea. Even a very low CFM fan is much better.

Note that this review dates from more than two years ago, long before the X79/LGA2011 systems were introduced. The Armageddon does not come with the mounting hardware for an LGA2011 socket; you'd have to buy that separately.
