Around late 2021, Fractal Design launched their new collection of AIO coolers called Lumen. Today, we’re bringing you our Fractal Design Lumen S24 RGB Cooler review which will focus on this specific product.
The Lumen coolers are available in both RGB and non-RGB versions. But in this review, we will focus on the Lumen S24 RGB Cooler to give you an idea of what it’s all about. We’ll discuss everything from its design and functions, then all the way to its performance.
But first, let’s check out its packaging and the extras Fractal Design included in their package.
We were excited to receive our package for this Fractal Design Lumen S24 RGB Cooler review. There’s nothing special about the packaging since it looks like every other box from Fractal Design. But despite that, we love how durable and sturdy the box is for protecting the contents inside during transit.
The front of the box showcases a bold and strong design with a big, clear image of the AIO cooler. You’ll also see its ARGB lighting on display which gives you an idea of how it looks.
On the box’s rear, you’ll see all of the cooler’s key features and product dimensions. The radiator’s dimensions can be seen on the block diagram, as well as the socket compatibility details.
In the box, you’ll find the Lumen S24 RGB Cooler, a user manual, and one brochure. The latter gives you instructions on how to reach the manufacturer in case you receive a faulty cooler.
You’ll find an Intel backplate, AMD ring bracket, and an Intel Ring bracket which is pre-installed on the block. There are four thumb nuts, four black spacers, four Intel LGA20xx standoffs, four Intel other-socket standoffs, and five washers.
The company even included two AMD mounting pin brackets plus Phillips 6-32 long and short screws (eight for each). Then lastly, there’s a cable for connecting the cooler block with a regular 3-pin ARGB header on the board.
Now, let’s continue our Fractal Design Lumen S24 RGB Cooler review by looking at its build, style, and functions.
We inspected the design and build of the cooler for this Fractal Design Lumen S24 RGB Cooler review. From there, we noticed how much of a strong, professional, sleek, and premium aesthetic it gives off.
It definitely looks like an AIO that’s designed to get the job done while being very good at it too. And since it’s an AIO cooler, there are numerous key components that were included in its overall design.
The cooler’s radiator is, compared to other AIO coolers, quite interesting and unique. It’s made of aluminium which helps it stay nice and lightweight. It also sports an APALTEK design, so the blocks on each of the radiator’s ends aren’t rectangular, but rounded instead.
The water pump’s main power input is found along the rear portion of the radiator. This specific placement may appear a bit odd, especially on a more practical level. However, it does make concealing the power supply’s cabling management much better.
The hose that connects the radiator to the CPU block has a generous length. It measures approximately 50.8 to 76.2mm longer than what you’d often see on other models.
We love how the CPU block sports an exceptionally clean and neat design that matches its notably slim form. This area is where some of the ARGB action takes place. But despite that, it still appears sleek and eye-catching even when the lighting is switched off.
As we mentioned, its CPU block isn’t huge and chunky unlike most of the designs of AIO coolers. As such, we can’t see it posing any problems or issues when it comes to system compatibility, specifically with RAM.
To get the best from its ARGB lighting effects, you can remove and rotate the cap at a 90-degree angle. That means you can install it any way you want without hindering the product from working how it should.
When it comes to controlling the pump’s built-in ARGB effects, you have a couple of options to choose from. That’s because it supports ASUS AURA, MSI Mystic Light, Gigabyte Fusion, Razer Chroma, and ASRock Polychrome.
Instead of giving you some thermal compound that’s kept in a tube, Fractal Design opted to have it pre-applied. That means the cooler is ready to install right out of the box. The placement and quantity of it is enough for both AMD and Intel processors.
If you’re inexperienced when it comes to CPU cooler installation, having the thermal paste pre-applied will be extremely helpful.
Now about the contact plate, it’s really nice and huge. And with the exception of HEDT models like the AMD Threadripper, this should offer amazing coverage for your CPU.
It sports a nicely polished copper design combined with quality components to make it work better. Plus, you’ll get to take advantage of notable CPU temperature results when used even under loads.
Let’s continue with our Fractal Design Lumen S24 RGB Cooler review and now discuss its RGB fans.
This AIO cooler is 240mm and it comes supplied with two 120mm cooling fans. The Lumen cooler features the company’s newly-released Aspect PWM fans that have daisy-chainable ARGB/power connectors. Additionally, these come pre-applied with adequate thermal paste coverage, making it an ideal product for both newbie and seasoned builders.
Fractal Design kept the clean and sleek black aesthetic combined with off-white blades to allow the ARGBs to fully pop. And taking a closer look, you’ll notice that this is Fractal’s own design which is certainly promising. With this, you can see that the fans were specifically chosen to perfectly match the Lumen S24 RGB Cooler.
Key Features of the Fractal Design Lumen S24 RGB Cooler
Our Fractal Design Lumen S24 RGB Cooler review will give you a whole list of all the cooler’s key features. Here are all the aspects that make it a favourite among many.
