Corsair H115i RGB Platinum AIO Cooler Review

If you’re someone who takes notice of what’s going on in the cooling industry, you’ll notice that Corsair has been in this sealed loop AIO game for the longest time. There have also been a ton of really great coolers that appeared in the market, as well as devices that utilize silence as the pinnacle and main feature of a great AIO.

But today, let’s take a look at Corsair and its H115i Platinum AIO Cooler which is the updated design based on their older models. The difference with this is that it features an improved cooling block, as well as regulated controls for fans and pumps. Beyond the cooling capacity of the latest entry, we’ve noticed a lot of changes that happened to its Hydro Series coolers: the company returned its square head with a silver surround instead of gray. This time, a metal ring is also applied with brushed textures and metal colorations.

Its hardware changed and you won’t see any of the plastic nuts previously set on its backplate. The style of its standoffs have also been improved, and that also goes with the thumb screws that come along with it.

What’s interesting about the device is the fact that it’s based on a 280-millimeter radiator which provides a bit of cooling to the surface area. It’s a cooler that’s easy on the eyes and comes with convenient tool-free installation. So without further wait, let’s take a peek and learn more about the H115i Platinum AIO Cooler from Corsair.

Corsair H115i RGB Platinum AIO Cooler Review – What’s in the Box?

The package of the H115i RGB Platinum is vibrant and has a lot of things going on on it. On the left, you’ll find the Corsair logo that also mentions of the 140-millimeter fans, iCUE, and its five-year warranty. In the middle portion of it is a view of the device itself. You’ll get a glimpse of all the platinum on it, and there’s also a mention of the multi-zone RGB head unit on it.

On its longer side panel, the left half conceals the compatibility, as well as the inclusion of iCUE. Just make sure you have an additional USB 2.0 internal header. The right half portion features all the accessories that are included in the package. These are the cooler, the mounting hardware, two ML-140 fans, an instructional guide, and the iCUE cable.

For the smaller side panels, both are similar in ways that these feature Corsair’s logo and name at the top. Just below, you’ll find details about the device’s performance, quiet-cooling capabilities, and magnetic levitation fans.

At the back of the box, you’ll find details about the pair of ML-140 fans plus their copper cold-plate, customizable lightings, head units with controlled RGB LED lights, plus, there’s also a zero RPM mode present. To the right, you’ll find the dimensional rendition of the radiator, and a list of vital technical specifications.

Once you get to open the box and remove the dense layer of foam, you’ll get to see all the components nicely packed in a partitioned internal package. Corsair made sure that everything is fixed in place to ensure that all parts do not meet or clash against each other during transit.

The Product

Corsair H115i RGB Platinum AIO Cooler Review

The pump has 16 individually manageable LEDs, and the bundle includes two ML-140mm Pro RGB fans plus four LEDs each. These are all managed via Corsair’s iCUE software, allowing you to sync your lighting with other Corsair products like their gaming keyboards and mice. There are tons of effects available, and there’s surely a preset that’s up to your preferences. If nothing’s up to your tastes, you can freely control the LEDs on your own, and Corsair made sure that the interface is user-friendly and easy to do.

When it comes to its cooling hardware, the pump has been improved with a thermally-optimized cold plate giving it a more quiet operation. Its magnetic levitation fans are a great inclusion too, reaching up to 97 cubic feet of air / minute while simultaneously offering a 0 RPM option for quietness when your CPU isn’t under heavy load.

As for the installation process, it is straightforward and easy, as long as you have a computer case that comes with a cut out right behind the CPU. If you don’t have anything like it, you’ll need to remove your motherboard then install your Intel backplate. If you’re an AMD owner, you won’t have that issue since the mounting blocks and stock plate are utilized. This means that your installation process can be finished in as quick as 15 minutes or so.

It’s nice that Corsair included a USB cable that links to a micro USB port on either side of the pump. The right-angled connector can’t really be seen, but it directs the cable towards the north. We also found out that it was lengthy enough to route out of sight behind your motherboard to a header right at the bottom.

As for the fans, these have lighting and power connectors that all link to matching connectors from the available pump. With that, you won’t need to spare RGB on the motherboard. You’ll really just need to find space at the back of your motherboard tray if you want to keep them out of view.

The dimensions of the H115i’s radiator is 322 x 137 x 27 millimeters while the fan’s dimensions are 140 x 25 millimeters. Fan speed goes from 0 to 2,000 RPM and its noise level is only at 27 dBA. Its fan static pressure goes at 3.0 millimeters – H20.

Cooling the device’s radiator is a pair of ML Pro RGB 140-millimeter PWM fans from Corsair. These have a range of 400 to 2,000 RPM which allow the fans to deliver around 97 CFM of airflow. With that, you’ll not only get a lot of airflow, but you’ll also have fans that are rated 3.0 mm-H20 for its static pressure; plus, a combination of high-flow and adequate push to be able to go through increased FPI radiator. This is something that you’d need for delivering high-end performance.

Using the Product

With the H115i RGB Platinum, Corsair have focused on the RGB and the coolers fans while simultaneously providing you with a cooling performance that matches its predecessors, which is a great thing.

It’s a really good all in one cooler and could even reach the performance level of your own custom liquid cooling; plus, the H115i RGB Platinum AIO Cooler does give you a lot of cooling capacity which is really great.

With that, you’ll need to move towards the noise levels and aesthetics of the device. Corsair’s inclusion of these types of fans are also really good, and in all honesty, we think that these are among the best fans in the market.

The fans do make a little bit of noise at 12v but the noise level is hardly noticeable. Thing is, these aren’t made to run at 12v, they’re better for low RPM airflow running at a lower voltage which is above the level of airflow that is common in a lot of fans today.

And since the fans don’t do exactly that low RPMs, the equipment gives you decreased acoustics but with more airflow. All in all, that’s what these fans are all about. It’s also great that the fans are PWM-compatible and feature a total of 24 addressable LED lights.

If you choose to mix this with iCUE which lets you manage everything in the software, you’ll realize that you did a great job at purchasing a highly flexible solution that also looks aesthetically pleasing. All you need to do is pop the unit, set this in a balanced mode, then you’re all set.

Much like in other models from Corsair, the H115i RGB Platinum AIO Cooler is easy and quick to install via its mounting system. The device is factory-filled with coolant in an enclosed loop; you’ll just really need to install its backplate, its standoff screws, then position the cooler where you want it then secure it in place. Its sleek black design will definitely make this excellent kit look perfect on any PC.

We can say that the H115i is a perfect alternative to heat pipe coolers with the additional benefits of being quiet, nice-looking, and performs excellently. It’s also great that you don’t need to be too tech-savvy to install the device.

All in all, we think that the device’s overall performance is great, so we’re highly recommending this H115i RGB Platinum AIO Cooler to you.


The iCUE app from Corsair is the company’s universal software program that lets you keep track and control RPM and its temperatures; you can also make changes the LED coloring and a whole lot more. This program is where the magic happens since it can control selected Corsair devices.  The great thing about this software is that you can set different devices to have the same pattern at the same time.

Inside the fan loop, you will find the coolant temperature inside. You will also find the lighting system. If you’re not fond of RGB, you don’t need to activate this; another option is to set a static color if you want to simple lighting.

Additionally, iCUE is not only used to set a color animation of Corsair’s logo on the cooling block, but you can also use the program to match any RGB color. For example, if you are using an ASUS ROG motherboard, you’d most likely choose red and if you’re using a Gigabyte Aorus motherboard, you might go for orange.

This may seem subtle but completing your PC’s color theme gives a finished feel to your build. Keep in mind that you can sync all your Corsair components with iCUE.


The overall looks of the Corsair H115i RGB Platinum AIO Cooler are great. It’s all black with subtle grey accents which make it pleasing to the eyes. The LED unit on the cooling block and the chrome element are the new features of the cooler; these are also fully programmable.

The sixteen RGB LEDs can also be individually customized, which allows for impressive effects. The best thing about the LED effects of this cooler is that you can make it as loud or as subtle as you want since you can configure everything based on your preference.

To conclude, the H115i does not only have impressive looks, but it also performs well. Its acoustics are low and it’s easy to install. As for the iCUE software, it’s a great program that had given a lot of options for customization. If you’re looking for a high-quality cooling device for your build, we highly recommend the Corsair H115i RGB Platinum AIO Cooler.
