When it comes to AIO coolers, 360mm radiator-based systems were the biggest you could get, that is, until recently. Since the appearance of the 420mm H170i Elite Capellix, it confirms that this type of radiator can provide optimised cooling. So today, we’re going to focus on this product here in our Corsair iCUE H170i Elite Capellix CPU Cooler review.
The H170i Elite Capellix is similar to the H150i Elite Capellix from last year. But the difference is the H170i has a bigger radiator with a boost in its overall surface area. It’s perfect for those who want to cool their top-notch chips from each camp.
Corsair iCUE H170i Elite Capellix CPU Cooler Packaging
Let’s start off our Corsair iCUE H170i Elite Capellix CPU Cooler review by looking at this CPU cooler’s packaging. We’re also going to check out what Corsair included with it.
The packaging for this product is similar to that of the H150i which also sports a bright yellow theme. To know how it looks, an image of the product is on the box’s front, at the centre.
On the left and right sides of the package, there’s another image of the product. However, it is set on a bright yellow background instead.
Flipping the box, the rear provides you with more details on the unit. These include its features, specifications, and some illustrations to show the overall dimensions of the CPU cooler.
The top panel of the box is where you’ll find the supported sockets. You’ll even see a list with images featuring different hardware that’s included in the package. To note, these are the mounting hardware, RGB/fan controller, and more.
Inside the box, you’ll find the H170i Elite Capellix kept securely in place. It’s to avoid any possible damages that it may incur while in transit.
Corsair also supplied the necessary parts for mounting such as 24 washers, 24 fan screws, and 12 radiator screws. In addition, the company included four Intel 115x standoffs, four Intel LGA-20XX standoffs, and four AMD s-TR4 standoffs.
Other items include four thumbscrews, two AMD screw clips, an Intel backplate, an Allen wrench, and an alternative pump cap. You’ll even find a set of AMD, AMD s-TR4, and Intel mounting brackets present.
Lastly, there are three 140mm ML-series ARGB fans, a Commander CORE RGB/fan controller, and a couple of paperwork.
Now, we can talk about the cooler’s design and functions in our Corsair iCUE H170i Elite Capellix CPU Cooler review.
Corsair iCUE H170i Elite Capellix CPU Cooler Review – Design and Functionality
The H170i Elite Capellix from Corsair is their biggest ever AIO. It features a huge 420mm radiator as well as a Corsair pump that’s controlled via the iCUE system. The pump can also be controlled using the stand-alone Commander CORE.
Aside from these, the cooler also features three ML-140 RGN fans.
Just as expected, the craftsmanship of all the components in this product is first-class. So of course, we couldn’t find anything to criticise the H170i Elite Capellix. The choice of materials used for this CPU cooler is excellent, so you can expect a premium product like usual.
Although the radiator doesn’t appear intimidating, it is still considerably bigger than the usual 360mm type. Its size is the limiting factor for your build since a lot of chassis still don’t support this radiator’s size.
When it comes to the aluminium heat exchanger, it looks and feels like that of the unit from the H150i. The only exception is its size.
At the centre of the H170i Elite Capellix is the current generation pump from Corsair. It’s designed for monitoring and lighting to be controlled via the Commander CORE controller. However, it’s also good to note that a 3-pin tach header is present for controlling the pump’s speed.
The Intel mount brackets are pre-installed, but they easily slide off if you prefer using AM4 or s-TRX4/TR4 brackets. There are also a pair of 90-degree fittings (swivel) that allows tube adjustments. As for the tubing itself, they’re covered using braided nylon sleeves.
The pump block features an octagonal form with four long and short sides. We think it’s more visually appealing compared to most AOIs around. And if you’re someone who prefers boxier shapes, then the H170i Elite Capellix is ideal for your tastes.
Both the outlet and inlet fittings are the swivel types and have a good degree of rotation. For its wiring, it’s positioned along the top portion, allowing you to better and easily route your cables.
These can be replaced with another facelet that’s included in the package. This is, if you’re searching for a varying visual aesthetic or additional ARGB lighting.
One is the glossy-black type, while the other appears more transparent. The latter lets lighting effects appear through the opaque pump face. This displays 33 separate LEDs according to your preferred design pattern.
Even after the cooler’s installed, you can remove then swap the Allen head screws easily. Just make sure that you don’t misplace the provided wrench.
And just like the H150i, the H170i Elite Capellix features the same pump. So, it comes with 3 Capellix ARGBs for better illumination.
The H170i Elite Capellix utilises a copper block plate that’s applied with a thermal compound. It’s actually more than enough for Intel CPU and AMD AM4 applications. However, better thermal paste is needed for Threadripper installs to guarantee complete coverage.
This product comes with three ML-140 RGB fans from Corsair. These are equipped with magnetic bearings that produce noise levels of 10 to 26 dBA.
These have a span feed of 400 to 2000 RPM, and each of the fans have eight addressable LEDs. These are installed right at the centre of each fan. These are linked to the available Commander fan controller.
You’ll get a black-clad design with hints of grey, making it a product that’s highly appealing to the eyes. Thirty-three RGB LED lights are present in the pump which can be addressed individually for awesome effects.
Its LED system can be as subtle or loud based on your preferences since everything can be properly configured. If you’re someone who isn’t into RGBs, you can choose not to activate or set a subtle static colour instead.
Commander CORE Control Unit
This control unit offers proper management and control over the pump, fans, and lighting of the H170i Elite Capellix. Not only that, but it can even manage extra 3 or 4-pin cooling fans and other devices. Just make sure that these are compatible with the iCUE system of Corsair.
The Commander CORE is powered by one SATA 12V plug, and it directly interfaces to a 9-pin motherboard USB header. Plus, it has adequate length for tucking and fitting the control modules away for a cleaner and neater look.
Be sure to remember that for lighting, only Corsair-branded LED strips or fans can be used and connected here.
Our Corsair iCUE H170i Elite Capellix CPU Cooler review will now focus on the different features of this CPU cooler.
