Computex 2017 was a very special event for Reeven especially as they presented the Naia 240, a closed loop cooler that is designed to provide great cooling capacity at an affordable price. As a bonus, you also get a very beautiful design that is in unison with Reeven’s concept “Perfect user experience. Even though the AIO solution for cooling CPUs was announced in May 2017 the actual model was shown at the Computex event in 2017.
Having this in mind, let’s proceed with the article and take a closer look at the first all-in-one liquid CPU cooler ever created by Reeven. There’s no notion of where the name came from, so we can only speculate whether the name is supposed to resemble an idea or a concept of some kind. Yet, it does sound like a naval heroine to me, quite frankly.
Getting closer to the product packaging I can say it’s a very good looking package and product presentation. Reeven kept their color scheme and this is definitely the accent in place for this AIO cooler. Yellow and black color dominance is observed all around the carton box, and most importantly it resembles the company in a way, making its product box more recognizable on the shelves in the store, or online. Text appears quite contrasty on the box so you can easily read more about the product, technical details and such. Let’s delve into more detail by slicing the duct tape and opening the package.
Reeven’s first attempt at the water cooling solutions for CPUs is with a larger cooler featuring 240mm water cooling radiator. Additionally, the package includes 2 x 120mm air pressure fans to allow great cooling capacity. All of this measures at (W)272 mm x (H)52 mm x (D)120 mm. The box I received contained the cooler and all relevant accessories. I will definitely take advantage of this cooler by testing it at maximum speed aiming to cool down an Intel CPU at several clock speeds.

Mentioning accessories I have to say that the entire assembly package was carefully ordered in a recycled, thick paper mold (as is the case with most AIOs). As an additional layer of protection for the radiator fins, there was the presence of a company and product labeled carton wrapped around the radiator itself. Excellent protection and good thinking there. Even though there were no additional protective materials like styrofoam, the package was intact and all parts appeared to be in pristine condition. Additionally, the mold is made to hold all parts neatly and tightly together to avoid any chance of moving around.
As I’ve covered the externals, let’s move forward with the inspection of the included accessories after removing the protective nylons.
reeven NAIA 240 ADDITIONAL ACCESSORIES
While testing a Reeven product is first for me as a tester and reviewer here at DVTests.com, I can honestly admit that my initial impressions were quite good, to say the least. In essence, the quality of the product itself, along with the other included parts and accessories is on a very high level. As another mention – let’s not forget this is Reeven’s first AIO cooler. The first bar is set quite high. Moreover, they have included parts that don’t always come included even with the most expensive manufacturers. This is definitely a thing of note.
The Reeven NAIA 240 accessories pack includes:
- Coolant (dye)
- Coolant bottle
- Test Cable
- Anti-drip bowl
- Back Plate – Intel and AMD
- Mounting bracket
- Backplate bolts
- Silicon washers
- Thermal Paste
- Big screws
- Coldwing 12 fans
- Long Screws
- Small screws
- Splitter cable
- Installation guide
Clearly, by all means, this is a rather extensive and as rich as it gets additional accessories package. One of the best I’ve seen when compared to other AIO solutions. These parts will allow you to have excellent compatibility and even future proofing. Additionally, you can dye your coolant to match your system color scheme. Definitely, Reeven wants you to have a great experience with the product they made.
After checking the extensive additional accessories package, let’s move on to the next piece I’ll have to examine. A closer look at the AIO’s structure and design.
reeven naia 240 STRUCTURE
In order to be able to fully explain and write about the details and features of the product, I spent some time examining it. This will ensure that I’d give the readers as an objective opinion as I possibly can. From the few minutes, I spent examining the cooler I can share that it is a high-quality product with innovative design and definitely engineered in a professional way. What makes the most impressive is the water block itself. Its unique design is accompanied by the great feel and quality of the tubes, fittings, and radiator. To top things off there are 2 high-quality Reeven fans bringing excellent performance in the cooling capacity.
So let’s start with checking the water block’s design and looks.
|Closer look at the water block||Naia 240 main components|
Naia 240 comes with a huge water block that packs quite the performance features. Additionally, it’s also the culprit of the overall look that comes with Reeven’s first ever AIO. The water block measures in at 95 mm x 67.5 mm x 63 mm. Having such a size means one thing – lots of things are happening in that segment of the cooler. Let’s go ahead and take a closer look at the water block assembly.
First off we have the essential part in the face of a finely milled, slightly curved CPU contact plate, or baseplate. It’s a copper plate, octagon shaped, covered with nickel coating and is relatively non-reflective. To ensure its longevity and trouble-free operation it’s attached to the water block via 8 screws. Its main purpose is to drive the heat from the IHS of the CPU to the liquid inside the block, thus allowing for the cooling process to take place. With this contact plate, Reeven is introducing Micro Channel technology. Essentially these are microchannels with 0.11 mm of spacing between each other, resulting in overall increased performance and more efficient heat transfer.
Speaking of liquids, let me share some information about the water pump that is the driving force of Naia 240. Reeven is using the WAP design (Water Above Pipe Design), allowing for the cooler to be installed in any orientation without compromising its performance. The pump is capsulated within the water tank, which by the way is quite user-friendly. Reeven has included a refill port, also it’s transparent so you are in control of the liquid at all times. What’s genius about it is that you can measure whether there is enough level of liquid only with a glance. That’s right. When mounted check if the liquid is leveled with the Reeven logo (70%). If that’s the case then that means you have to refill. A handy way to make things happen.
Another great feature of NAIA 240 is the presence of dye. You have 3 colors to choose from – blue, yellow, red. Using these you can make the liquid in the AIO look quite fancy and match your system’s color scheme. Lastly, covering the tank we have the company logo, looking elegant and clean. It’s a brushed metal text on a black background.
Two plastic fittings are coming out of the water block assembly, connected to the hard plastic base. This base holds the water block connected to the mounting plate via 2 screws. Adding to that, the power cable connector for the entire unit comes out of the base. It’s 4-pin, black, flat cable with sufficient length.
The water block is high quality, to say the least. It feels quite sturdy and solid, a metal cap is used to keep the refill port closed and sealed. Very hard plastic is used for the base of the water block, and transparent thick plastic for the tank. The same sturdy and good feel can be said about the plastic tubes attached to the fittings. They are long, flexible and sandy not rubber. As they are made of plastic they have limited flexibility and bend to them, yet I had no issues installing the AIO. They end in the water radiator, which is the next thing I’m going to show you.
Let’s take a look at it, its dimensions and characteristics.
|Radiator fittings||Side/front view of radiator and tubes|
Reeven Naia 240 is equipped with a 240mm water radiator made from aluminum. Its physical dimensions are 272 mm x 120 mm x 27 mm. It is compatible with two 120mm fans that come included in the package. The fins of the radiator are with medium density and comprise the cooling surface. The entire radiator is painted in matte black. It serves as a protective coating and also provides a premium look and feel to the product. All of the sides of the radiator are clean looking with no logos or visual features. Again, as is the case with the rest of the AIO from Reeven, there is a resemblance of high quality and excellent durability all around this product.
As I mentioned the 2 fans included in the package, let’s check them out as well. Naia 240 comes with two 120mm Reeven Coldwing fans, featuring a black square frame with dimensions of 120 x 120 x 25 mm and black propellers. Both fans generate high airflow and static pressure which is essential for the smooth operation and cooling capacity of most water-based coolers. The propellers’ 11 blades are shaped and angled in a special way to allow greater airflow with low noise output.
Both fans are able to generate a maximum of 90.28 CFM each when running at maximum RPM. They are rated at 12 volts and the operating range is 300(+300/-100)~1600(±10%) RPM. When spinning at their lowest speed of around 300 RPM they generate 16.93 CFM of airflow. As they are designed to penetrate the aluminum fins of the radiator they produce between 0.003~0.08 inch H₂O of static air pressure. Power comes through 4-pin PWM fan connector and a long, black nylon sleeved cable.
All of these figures are coming from a relatively quiet fan duo. Coldwing fans are measured to produce between 6.5~30.9 dBA of noise. They use Sleeve bearing type and are rated for 30,000 hours of MTBF. Naia 240 is weighing at 1,290g when fully equipped with fans and liquid.
In order to mount the fans to the radiator, I will use the included 8 long screws.
And this is what the fans look like mounted on the radiator.
Now that I have assembled Reeven NAIA 240 in full I will have to undertake the process of testing. It’s a sleek looking cooler with a simple, yet elegant design and a ton of great technical details and features.
Next step in the article would be to mount the cooler and perform the testing part. According to the official data from Reeven website and Naia 240’s package box the cooler is compatible with:
- Intel sockets: LGA 115x / 1366 / 2011(V3) / 2066
- AMD sockets: AM2(+) / AM3(+) / FM1 / FM2(+) / AM4 / TR4 (Upgrade Kit required!)
For this tests, I will be using the Intel mounting hardware for socket LGA 1150 on Asus motherboard. Backplate, mounting bracket, nuts, spacers, and screws will be used in the process. Take a look at the photo below for a more detailed view of the mounting hardware:
These are all of the parts which should be assembled so I can install the water block to the processor on my motherboard. Let’s begin.
|Backplate and spacers installed||Mounting bracket installed|
The first step is to align the Intel/AMD backplate to the correct socket holes, run the screws through them and put the spacers in. Next, you should place the mounting bracket on top and secure it with the 4 nuts. Tighten until you feel resistance, but don’t overtighten them as this puts a lot of strain on the motherboard.
With this in mind, your next step should be to put some thermal paste on the CPU and top it off with the water block while aligning the two holes. Secure it in place with the 2 screws and tighten them until full stop. Naia 240 is now mounted on the motherboard and here is how the cooler looks:
After taking these steps I can say that the process was very easy and extremely well explained in the installation guide. It’s a piece of cake really. In addition to that, I was surprised by the great fit that the block and CPU. This speaks very well of Reeven and hopefully will be the reason for great results.

And this is what the AIO looks like installed back into the case ready for the stress tests.
|Inside the case||Reeven Naia 240 AIO|
While installing the cooler I didn’t experience any RAM clearance issues, actually quite the contrary. Although my RAM is installed in the second DIMM slot there was enough space. Nonetheless, even if it was in the first slot this would have posed zero issues. In reality, there are at least several millimeters of space left between the RAM and fittings.
I believe have now completed with the review of the Naia 240 and with the AIO fully installed inside the case I believe it is time to check my test rig and continue the article with the stress tests.

For this test and review, I am going to use the standard Coldwing 120mm fans working at full speed of 1600 revolutions per minute providing airflow level of 90 CFM at a noise level of 30 dB(A).
The tests were conducted in a closed system with:
- 2 x Silverstone 120mm case fans – front panel putting fresh air in and spinning at about 900-1000 RPM
- 1 x Silverstone 120mm case fan – rear mounted, serving as exhaust and spinning at about 900-1000 RPM
- Room temperature of about 22 degrees.
The Silverstone 120mm fans were connected to the motherboard fan headers and were rotating at maximum speed.
Therefore I want to describe my testing method.
I will install Naia 240 and do stress tests using Prime95 AVX software with constant load on the cooler for 14:30 minutes with custom settings of minimum FFT size (in K of 128), max FFT size (in K of 128) and Run FFTs in place at standard frequency of 3.400 MHz (at Auto Voltage), at low overclock frequency of 3.900 MHz (at 1.205V) and at medium overclock frequency of 4.300 MHz (at 1.23V) using the fan provided with the AIO system rotating at maximum speed and the water pump running at maximum speed of 3000 revolutions per minute.
Now let’s check out the test results that Reeven Naia 240 was able to deliver:
|Naia 240 @3.4 GHz Idle||Naia 240 @3.4 GHz Load|
|Naia 240 @3.9 GHz Load||Naia 240 @4.3 GHz Load|
All of the test results have also been summed up in the following charts:
And the fan speed while the tests were running:
Finally, the water pump speed during the tests:
I believe it is time to express my feelings regarding the product.
reeven naia 240 CONCLUSIONS
1. Reeven Naia 240 performance:
This is probably one of the best AIOs I’ve ever had the pleasure of testing. Since I had enough time spent with the Naia 240 cooler I can deliver an objective opinion about it. By all means, this is a great CPU cooler, especially for the price it’s being sold at. And certainly a good investment and future proof (CPU cooling wise) piece of hardware. Moreso, looking at the results it’s obvious that it can handle even more heat. With this in mind, take a closer look at them, judge for yourself and leave a comment in the comment section below.
In general, the noise coming from the unit is quite bearable, to say the least. All things considered, we have a high RPM pump and 2 fans spinning at medium to high RPM, whereas in comparison to an air cooler you have 1 or 2 fans in most of the cases. Surprisingly the unit is relatively silent and little to no parasitic noises are coming out of it while operating. No noise from the pump is emitted, no abnormal sounds of air bubbles coming through the pump as well. All in all the fans are also very quiet when compared to other units I’ve tested. For the most part, it’s a rather silent AIO and more a great first product in Reeven’s portfolio in this product range.
On the negative side – the tubes. I’m not a fan of the hard tubes, especially when using a mid tower case. Should you own a larger case and lots of room to play with you are fine. It’s important to realize that most novice users may have a hard time installing the unit alone without a second pair of hands, due to the less flexibility of the hard tubes.
All things considered, I think this is a best buy if you are on the lookout for AIO solution of this range and size.
2. Reeven Naia 240 appearance:
From the very beginning when I opened the box I knew this cooler was something else. Although it slightly resembles the RAIJINTEK Triton I have to admit that the Reeven cooler is better looking. One of the main features is obviously the included 3 bottles of dye and that’s a great user experience. Reeven has done so much with this cooler and didn’t forget about one of the most important aspects of a product – it’s customizability. Even without adding dye the transparent tank looks great as it is accompanied by an LED that emits light once the computer is operating. Imagine how this will look like when dyed.
The black matte paint that is used is of high quality and protects the product from small scratches. It also adds that additional layer of premium finish. Furthermore, the black fans complete the overall package and this stealthy looking beast of a cooler is ready to cool down the most if not all hot CPUs. Even overclocked too. Without too much compromise in silence, thus I can say this is one excellent piece of AIO. Great job to Reeven!
In conclusion, after my tests and review, I think that Naia 240 deserves the following award:
Official Reeven Naia 240 (MSRP) price: 109 USD
Official warranty: 24 months
Special thanks to Reeven for providing us with a test sample!
