SilenX's installation kit includes a top bracket that fits all popular desktop CPU sockets (LGA 775 to 2011, AMD Socket 939 to AM3+), a base plate that supports most popular performance-oriented processor interfaces (except for LGA 2011), and an extra set of mounting screws for LGA 2011’s integrated cooler support plate.
SilenX的安装套件包括一个适用于所有常见桌面的CPU插座的顶部支架（775至LGA2011，AMD Socket 939到AM3+），一个支持最流行的业绩导向处理器接口的基板（除了LGA 2011），和一套适用于集成的LGA2011散热器支持板的额外的安装螺钉。
SilenX's universal top bracket screws to the sides of the cooler with its ears pointing towards the bottom, as shown.
The EFZ-120HA5’s top bracket is then attached directly to the LGA 2011 cooler support holes using spring-loaded screws. This is the point where everyone who doesn’t have LGA 2011 can start crying about all of the extra steps they're forced to endure.
The most difficult-to-install part of the EVA-120HA5 kit is its fan. First, four T-shaped rubber tacks must be pulled through the fan's mounting holes (on its back side). The top of the T must then be slid into groves on the heat sink.
Unfortunately, the fan’s hole spacing is slightly wider than the heat sink’s height, leaving each T dangling precariously, as only half of its length is supported by fins. The Ts are soft, the fins are rough, so the lightweight fan isn’t likely to shift. But getting it centered takes a couple of minutes.
With its fan’s power lead plugged into our motherboard’s header, SilenX's EFZ-120HA5 installation is complete.
The Archon SB-E includes the cooler and AMD/Intel universal installation kit from Thermalright’s Archon Rev.A, plus an LGA 2011-specific standoff set.
Archon SB-E包括冷却器和AMD/英特尔来自于Thermalright’s Archon Rev.A的通用安装套件，加上一个特定的LGA2011对峙集。
While other platforms get to this point using long nuts and a separate support plate, LGA 2011 standoffs screw directly to the motherboard’s integrated cooler mount.
The Archon SB-E’s top bracket is installed onto standoffs using small screws.
Self-adhesive vibration dampening pads are most easily stuck to the cooler before attaching it to the motherboard.
The cooler is then clamped down to the hold-down plate using an included strap.
Note that the strap only centers the CPU cooler front-to-back, leaving around ?” of side-to-side adjustability.
The fan’s lead is then plugged into the motherboard, and the fan itself clipped to the heatsink. Note that the fan cannot be rotated 90° because its hole pattern is rectangular rather than square. No matter how far we slide the base, the Archon SB-E always hangs past our top video card slot. Thus, we were forced to test the cooler with our graphics card in slot position three, which means that it wasn’t tested in a standard configuration. We’ll make sure to mention this as we discuss our thermal findings.
Xigmatek uses the same bracket set as Enermax, though these are packed a little differently. Bushings for the aluminum pressure plate, for example, were found beside the plate rather than inside of it, and there’s no included wrench for the tension nuts.
Xigmatek labels its Intel and AMD brackets, though the AMD brackets are also drilled to fit Intel socket hole spacing.
This is how Enermax's installation would have appeared at the half-way point, had we used the other bracket set (minus the Xigmatek and Intel labels, of course). Cross brackets are mounted to LGA 2011-specific standoffs using thumb nuts.
With no wrench to play with, we tightened Xigmatek’s tension nuts using an electric screwdriver. The results are the same, with a slight space found between the cross brackets and the pressure plate when both nuts are fully tightened.
Like SilenX, Xigmatek uses rubber tacks to hold its Venus XP-SD1266 fan and heat sink together. Xigmatek’s design is better in a couple ways, including the fact that the sink is actually tall enough to hold the fan. The tacks are also slotted and hooked on from the sides, rather than forced in from above and below.
像SilenX, Xigmatek使用橡胶钉来保持其Venus XP-SD1266 风扇和散热器一样。Xigmatek的设计在几个方式中是比较好的，包括接收器是高到足以容纳风扇的事实。大头钉也被从侧面开槽和挂钩，而不是被迫从上面和下面。
Zalman’s CNPS12X installation kit supports AMD’s Sockets AM2 through AM3+, in addition to Intel’s desktop LGA 775 through LGA 2011. LGA 2011-specific standoffs let you get rid of the irksome support plate in favor of the interface's integrated mounts.
Zalman's CNPS12X安装套件支持AMD的最新接口AM3+ 、AM2接口，除了支持LGA2011的英特尔台式机，还有LGA775。LGA2011特定支架让你摆脱令人厌烦的支撑板，是有利于接口的集成支架。
Standoffs are threaded in first (foreground), followed by cross brackets and thumb screws (background).
At the edge of a factory-installed pressure bracket, factory-installed spring screws engage holes on the cross brackets to provide even pressure against the CPU.
Ah, but wait…isn’t that backwards? Zalman designed the CNPS12X with ?” offset to clear the top of your case, your power supply, or whatever else is above your motherboard. Unfortunately, that causes the cooler to overlap our motherboard’s main graphics card slot.
We were left to either put our graphics card in the wrong slot and partially discredit the results (as we will with one other cooler) or mount it in such a way that some of the air pushed through it would already be warmed by our graphics card and power supply. Choosing the latter means that the test results represent a performance floor, by which we know it performs "at least this well."
A final installation issue that affected our build was that the CNPS12X overlapped our secondDIMM slot and was just low enough to the motherboard that the fan tips barely touched our 1.55” DIMMs. Though we were able to make things work with a little adjustment, the solution wasn't long-term enough that we'd recommend this cooler to anyone with modules even a hair taller than 1.50”.
Zalman’s ZM-STG2 thermal paste is used in this test not to favor its cooler, but because Zalman has long been our thermal paste provider. It works equally well with other cooler brands, and settling on a single substance reduces variability in testing.
Our CPU and voltage regulator pull around 300 W at full load at this O/C, using an old C0 stepping Core i7-3960X at 4.60 GHz and 1.40 V. We used this specific processor because it’s the one we can most easily afford to lose (due to heat damage) after long bouts of overclocking.
我们的CPU和稳压器在O/C拉满负荷300瓦左右，使用一个旧的CO将Core i7-3960X加强到4.60 GHz and 1.40 V。我们用这种特定的处理器，因为它是一个我们在超频长期较量后几乎很容易丢掉的处理器（由于热损伤）。
Twelve threads of Prime95 provide 100% load. We were forced to test noise at extremely close distances to stay within our meter’s calibration range.
Noctua and Zalman are in a dead heat at the top of our CPU temperature chart, and its here where many readers will remind us that Zalman’s cooler was mounted backwards (where its intake air might have been slightly warmer).
We’d give Zalman the benefit of the doubt if the fitment issue wasn't such a concern. Besides, some builders (and some cooler manufacturers) prefer to see chassis exhaust fans mounted as an extra intake, though we can only suggest doing that with cases that have extremely good top-panel exhaust.
SilenX’s temperature here has to be recorded as an estimate as a result of processor throttling. You see, the displayed temperature is an average for all cores, and this processor begins throttling at 90° C. Without the ability to achieve lower (and less realistic) ambient temperatures, we simply couldn’t keep the warmest core below its throttle point.
