Let’s now take a look at installation on an Intel socket LGA 115x motherboard:

Take the backplate and place it on the back such that the cooler mounting holes in the motherboard coincide with a set of holes on the backplate. The manual does help identify which ones although it is fairly straightforward to see which ones they would be in person. Here is the tricky part- there is no way to keep this backplate in position while you secure it in place from the other side. As such, I strongly recommend doing this outside of the case. It is a weak point of the installation process for sure. You need to take the Intel mounting post for LGA 115x (not the ones with the thick, short M4 threaded end) and have a washer go through the shorter end as seen above.

With all four posts screwed in, take out the two piece Intel mounting bracket and screw it onto the heatsink as so using the provided screws. Note that you will need a Phillips head screw driver for this, and thus the AR07 is not a tool-free installation cooler. Time now to remove the sticker from the cold plate and apply TIM on the CPU IHS. Following this, lay the cooler down on the CPU IHS and around the mounting posts, you may choose the desired orientation (left-right or top-bottom) depending on RAM and PCI-E device compatibility.

Use the locking nuts to secure the heatsink in place and clamp it down for uniform pressure. Easier said than done, however, as these are open ended nuts meaning you have to guess how much to turn them for best pressure. Ideally, you would want to screw them in a cross manner for uniform pressure upto a point then run your CPU on a stress test and monitor temperatures/frequency stablity while tightening/loosening the nuts to get the best fit for your case. In reality, no one will end up doing this with this cooler and will just tighten down as much as they can which may or may not be a good thing for your particular CPU depending on your torque strength. Finally, note that this is the preferred orientation for builds as the other orientation will inevitably hit RAM slots, and the fan comes in lower thus reducing the height available for RAM sticks to lower than 25 mm.

Installation on Intel LGA 2011(-3)/2066 is even simpler. Use the M5 threaded screw posts and use them with the cooler mounting holes around the socket on the motherboard. Then apply TIM on the CPU IHS, and repeat the same steps as before. The size of the cooler coupled with access to the locking nuts makes it a lot easier to install here, although I would still say do this before installing system RAM in the slots.

Fan installation here was easier the way Silverstone recommends in the manual, as opposed to first installing it on to the tower. With the heatsink in place, take out the two rubber pads and place them on the fin stack on the flat section near the edge. Then use two of the fan clips such that the long section is held in place in the fin stack cutout on the sides, and the leading edge has the bent ends as above. Your goal is to pivot the fan to have the clip on one side go through the fan corner holes closest to it, adjust it and then do the same for the second clip by applying more force. Don’t worry about feeling like it is too much force, the fan and clips can take it. Finally, remember to plug in the fan cable to a PWM fan header- preferably the CPU_FAN header.

With the cooler installed, we see it is close but still fine with both RAM and the first PCI-E slot on this Gigabyte x99 motherboard. Some boards may have the cooler interfere with both, in which case you may have to use the outer slots accordingly. TIM spread was average as with the AR08 with streaks of paste getting in between the heatpipes in the direct contact section but otherwise having a large enough contact area to not be an issue here. I certainly would not recommend this for AMD sTR4 socket, and it is a good thing Silverstone has not made this compatible for it either. With this dealt with, let’s see how the cooler performs on the next page.
