Deepcool is well-established company specialized in PC Cooling Solution and have been around for many years. Founded in 1996 in Beijing and headquartered in Shenzen China, mainly investing in CPU Cooling solutions, PC case, Case Fans, and Accessories. The Deepcool name was inspired by the Deep Blue, a supercomputer built by IBM for Chess game. Quite interesting inspiration though. The research team over Deepcool has been focusing on Computer CPU Cooling solutions, Video Card cooling, laptop, and servers cooling solution. In addition, to proactively compete the market, they expanded their product line by offering AIO coolers, PC Chassis, and Power supplies.
The All-in-One Liquid cooler is one of the mainstream product categories for Deepcool and like other rival brands, Deepcool also have prospered its production in the said department. In today’s competition, Deepcool phenomenal designed AIO coolers have been dominating the market. Added with RGB, the AIO coolers delivers outstanding outlook coupled with steep performance.
Today, I am taking a look at the Deepcool Gammaxx L240 All-in-One CPU Liquid Cooler. The Gammaxx L240 is featuring 240mm black, Aluminum radiator having a dimension 274×120×27 mm, comes with 2x 120mm cooling fans. The 310mm long tubes are supportive to process the liquid and link with the CPU block. The pump speed is rated at 2550 (+/-) 10% with a noise level 18.9 dBA. The Gammaxx L240 comes with two 120mm cooling fans, which are rated to perform 500-1800 RPM, taking 12VDC and consuming 4.08W power. Having compatibility list of all Intel and AMD sockets, the cooler ensures 100% compatibility support across the platforms.
The package and the Content
The Cooler shipped in a premium wide box, which looks as proper as any other AIO cooler. The box is a bit compact for the AIO cooler with solid bold colors, mainly black and Blue. On the front, the ‘Deepcool’ logo with icons featuring RGB motherboard dedicated functions. Cooler’s picture in the middle and Gammaxx L240 with huge font at bottom.
On the backside, it has the features and specifications. Again the ‘Deepcool’ logo on the top left corner and product model, GAMMAXX L240, at the other end. Coming down a bit, the socket support list suggesting this cooler has full support for Intel and AMD sockets, in addition, the detailed specifications in tabular form is printed just below to it. On the right is the major offerings this cooler has got. The bottom row has a blue bar which contains the measurement of Radiator and CPU block.
The barcode sticker and warranty void sticker can be seen on one of the sides of the box.
Inside the box, the Cooler and the Components nicely packed in plastic bags. This is sort of standard packaging that we usually see in AIO Cooling solutions. With more components involve in AIO coolers, the packing takes more space to cover all of them in a single cardboard box. The radiator is firmly placed at one side of the box being packed in the plastic bag. The other end is the CPU block. In the middle, a couple of 120mm fans again in a plastic bag, in addition, we also see accessories and manual.
Unleashing the components we have All-in-one Kit, radiator fans, Accessories bag, manual and Fan Hub with RGB connectors.

The GAMMAXX L240 – A Close Look
The Deepcool Gammaxx L240 is a 240mm All-in-One Liquid Cooler. With All-in-One design, the cooler offers radiator, tube and CPU block to complete the product. The Cooler has a black radiator build with material Aluminum, while it’s dimension is 274x120x27 mm across the ends.
The build quality of radiator is pretty solid. The side of the radiator is shining and has 3 screws engraved into the panel meeting the body. There is nothing wrong with the finishing, in fact, it is recognized as one of the great finishing that we have seen. To mount the radiator in the case, the dedicated case screws will be used and there is a total of 8 locations that would need to be screwed tight on the case.
On the front, the barcode sticker is pasted, which contains the certifications and of course the warranty void text. If, in any case, this get removed (the white sticker), the warranty will be void.
The fins are actually looking just fine. There are some in the stack that is slightly bent, however, these are usually and mostly appeared in every AIO’s radiator. The gap between the fins is normal which positively helps to throw hot air outside. The water channel design helps in improving water circulation’s efficiency. Overall, the radiator fins are well made.
Tubes are medium to connect and channelize the water smoothly between block/pump and the radiator. The braided tubes are 310mm long, which connects radiator and CPU Block, cooperatively. The tubing is soft, flexible, and covered by nylon braiding. The ends of the tubing are metal clamps that attach to the barbs on both the radiator and the custom pump housing. The length of the tube is standard, which already is adequate for a standard Full Tower case.
The significant part of a cooling solution is the CPU Block. The Gammaxx L240 has a giant block with Ceramic axle bearings and axle cores. The top has the Gammaxx logo and a pump inside it. The pump dimension is 91 x 79 x 47 mm, using 3-pin connector the pump runs at a speed of 2550 RPM ± 10%, has a rated noise level 18.9 dBA. A highly efficient induction motor delivers stronger liquid flow and pressure. The speed will definitely vary even more than 10%, however, our tests will show the actual impact. The pump has a 3 pin connector 12 VDC with rated current 0.21A ±10% and manages 2.52W power consumption via motherboard’s fan header. Note that, a fan header draws 1 Amp (12W) maximum and with RGB the power headroom expands with 2 Amp, however, 12W stays same for the devices attached on it.
The top design of pump looks really cool. The outlook further enhances when the logo glows because it offers colorful RGB styling out of the box. To make it possible, the block connects with Motherboard’s RGB header, that is +12V G R B labeled header on the motherboard. Too bad, this cooler doesn’t come with any RGB controller because not all motherboard offers RGB header. This is one of the lacking Gannaxx L240 has got, yet you can use external RGB controller to function the RGB.
The bottom reveals the Pure-Copper base. An ultra-large, pure copper CPU block provides effective coverage and heat dissipation for CPU of any size. Having 55mm dimension across the base, the copper base leaves no lacking. About the effectiveness in thermal conductivity, the pure copper is subjected to highly effective thermal performance than rivals and is improved version of copper. There are 10 screws that can be seen on the base, which actually works to fix the base with the whole block.
We actually did open the base to show you the actual component inside. The inner part of the copper base is faced the plastic body of CPU Block.
Having black and White color combination, the Gammaxx L240 comes with 2x 120mm fans. Both the fans have rated speed of 1800 RPM ± 10% each with the rated airflow 69.34 CFM and 2.42 mmAq Air pressure. The fan model is DF1202512CM-013 powering up on 12 VDC, at 0.17A and power consumption 2.04W. This fan unit is using Hydro Bearing, which is also referred to Fluid Dynamic Technology. The Hydro/Fluid fans are considered to be the quietest fans, while the bearing technology typically bit noisy despite vast product line. The fluid has a little shorter lifespan than the double ball bearing. The purpose of FDB is to minimize the noise and keep the environment noiseless, especially great for ultra-low noise Rigs. The fan offers lowest 500 RPM, thanks to PWM function for extensive speed control. The 120mm fan takes 0.17W on 12V.
To begin with, we first mount the fans on the radiator. The 8x fan screws are used to mount the 2x 120mm fans on the radiator. We then move to setup the motherboard and CPU. We ready the CPU on the socket by removing the previous cooler and cleaning the old thermal paste.
Get started with mounting the back plate, which apparently silver in color having INTEL on one side and AMD on another side. We filled the INTEL 1151 compatible holes with Screw Bolt x4 and put the Insulative Cushion x4 on all the possible bolts. Yes, this is different but one thing is pretty sure that these cushions are extremely effective here and we appreciate Deepcool for introducing them. These Insulative Cushions hold the Bolts tightly, which indeed is an effective inclusion.
By following the manual instructions, we mount the Brackets on both sides of the block using 2x Nut A to fix it up. Now place the block on the CPU and tightened the four ends using 4x Nut B. A locally made screw driver is used to tightening all the Nuts.
Towards the finalizing, we connect the 4-pin connectors with deepcool’s dedicated Fan Hub, while the RGB connectors on the motherboard using 4-pin(+12V-G-R-B) connector. We mount the radiator on top of the case using 8x case screws and done.
Note that, If you’re interacting with the RGB product for the first time, then you need to ensure the header to be at a right pin sequence. The main RGB header has a pin sequence (+12 G R B), an unlike sequence will result in motherboard damage. In addition to this, the RGB header consumes maximum power on 2 Amp is 12W, while exceeding will result in damage. So be careful when connecting the RGB connectors. This cooler has three main female pins out (2x fans and 1x pump) which are not compatible to connect on motherboard header directly. The cooler comes with additional LED extension cable (having 4x extension connector) followed with RGB extension cable, which then finally interact with the motherboard header having pin sequence +12V G R B. Overall, the installation length was even shorter than we expected.
Showing off the final presentation with the CPU Cooler being installed in PC. The Glowing logo on CPU block has a fantastic look, to say the least. The design on the pump is special and dedicated to Gammaxx CPU cooler. It basically refers to Gammaxx lineup air coolers and water coolers, so does this product too. With RGB enabled, no matter what color theme your motherboard has or your desire to adjust, just set up your favorite collaboration and enjoy the beauty.
Most of the Z270 and all the Z370 motherboards come with RGB +12V GRB headers with dedicated RGB controlling software. This cooler support mainstream motherboards with synchronized lighting control, like Asus AuraSync, Gigabyte RGB Fusion, MSI Mystic Light Sync, and Asrock Polychrome Sync, which expands the offering and cover every PC user. In our case, we are using Gigabyte RGB Fusion software to change the colors and effects on Gammaxx L240 cooler. We took some of the cleared captured color schemes from the color cycle. Note that, for our camera to capture the color nicely, we had to bring down the color brightness via Gigabyte RGB Fusion. The result was entirely satisfactory. Honestly, the Gammaxx L240 with RGB enabled looks extremely exquisite, especially with the board being RGB added even more beauty. Just wondering, what other Deepcool RGB AIO coolers would offer in the display with even better lighting features.
Below is the video presentation of Gammaxx L240 RGB light effects. We don’t have a high-quality shooting device so please excuse the color bleeding. The lighting effects look far better with a naked eye.
Compatibility and Clearance:
The Deepcool Gammaxx L240 AIO cooler is free from any incompatibility corners as it doesn’t have components obstructing either side. We measured the block and it is about 91mm wide including the tube locks. The height of the block is about 47mm from base to top.
The socket support on this cooler is absolutely future-proof, as it supports all LGA 115x/1366/20xx with the distinctive supportive bracket comes in the package. On part of AMD platform, it definitely offers full support for across the sockets and apparently, the Cooler has included the kit that offers the latest AM4 and all the previous released since FM1.

Programs used in Tests:
- Prime95 26.6v (Blend Test)
- HWiNFO64 5.30v
- SpeedFan 4.50v
Our tests setup based on Core i7 6700K and Gigabyte Z270X Gaming 5. Further, we utilized Noctua NT-H1 thermal paste application using “Dot” technique. FYI, NT-H1 ranked in the top thermal compound around. As for airflow ventilation system, there is one fan, Noctua NF-F12 rated 3000 RPM (Intake).
We used manual settings in BIOS both on stock and overclocked clocks. The Core i7 6700K running at 4.0GHz (Stock) with a manual voltage at 1.15 vCore in BIOS (1.184 vCore in CPUz), while processor being overclocked at 4.5GHz Vcore at 1.25V in BIOS (1.28 vCore in CPUz). We used Prime95 26.6 ver., to torture the processor. This program tells the capability of CPU on stock and overclocked condition, of course under extra-high loads. All the test ran long for 15 minutes, which usually is adequate duration to probe and get the required results.
we have used Delta temperatures (Ambient Temp – Reported Temp) = Delta T
This method is especially suitable for variable room environment.
We tested the Deepcool Gammaxx L240 for single and comparatively analysis. We took Idle and Load temperature figures and ranked them up in charts. The results are as follows:
The idle temperatures at 4.0 GHz clock was sitting at 2°C delta T and on load, it maxed out 31°C delta T, while on overclocked clocks i.e. 4.5GHz at 1.25v, we have 52°C delta T. Here, the Gammaxx L240 is just behind to Reeven NAIA 240 by 2°C on stock, which is marginal, but matters. On overclocked clocks, the gap is stretched a bit where Gammaxx L240 is 3°C behind to NAIA 240 liquid cooler. Despite the average difference, Gammaxx L240 performance is optimal.
The cooling fans have an effective 1880 RPM (being reported in HWiNFO) with the rated airflow 69.34 CFM. The fan speed is already quite a lot to work effectively. According to software, the average speed is 1858 RPM and with 4-pin PWM, the fans were controllable as rated on specifications, 500-1800 RPM, is entirely true. On the other hand, the pump was maxed out 2861 RPM added 12% to 2550 RPM. This speed of pump ensured to keep the smooth flow of water without any limitation.
The Deepcool Gammaxx L240 is one of those AIO Coolers that offers highly flexible fan speed via PWM equipped feature; allow users to effectively control the speed of a fan, which further mitigates the noise. Of course, users do love to have a silence environment because the higher the noise, more disturbance will be made in a quieter environment. We, unfortunately, unable to record the exact values in dBA, but personal experience to share. The Gammaxx L240 has shown that it comparatively one of the good coolers when it comes to controlled noise environment. The Gammaxx L240 did create noticeable noise at 100% fan speed, however, the kind of noise was completely bearable. Thanks to FDB technology used by Deepcool in those fans. In our comparative analysis, the Reeven Okeanos was the noisiest cooler, while NAIA L240 was a quieter one.
- Beautiful outlook
- RGB light effects
- Great build quality
- Optimal performance
- Simple Installation
- Competitive price
- No external RGB Controller included.
- I don’t see any other.
All-in-One Cooling solution has been a prime choice among the Gamers and Hardware Enthusiast. The Deepcool has set an example of beauty and performance in a single product without any serious limitations. The Gammaxx L240 designed to perform and offers extensive cooling with effective 1880 RPM (2.42 mmAq) helps to dissipate the hot air quickly. The Cooler support all mainstream Intel and AMD socket, which makes this cooler future proof and free from any obstruction. The Radiator appeared as being worked carefully and nylon braided tubes were truly demanding in the market. The Giant CPU block with glowing Gammaxx Logo looks Exquisite. Replacing the Heatsink Air Cooler with Deepcool Gammaxx L240 Air cooler was a great relief.
Looking at the performance, the cooler has performed merely optimal. If we say perfect or extraordinary, that would be unwise. In our analysis, the Gammaxx L240 has just done what we are looking for. The 2x 120mm fans run at 1880 RPM which gives enough air to dissipate the hot air. The cooler manages to limit the CPU thermal 31°C on stock and 52°C on overclocked clocks. In comparison, with NAIA 240, the sample cooler ranked just behind by 3°C difference on overclocking condition clearly indicates the Gammaxx L240 is not the best in the business but works quite well in the department.
We liked the RGB effects on this cooler, especially with both fans being RGB the AIO delivered an amazing display in the gaming PC. However, we had to upgrade our motherboard in order to light up the RGB LEDs on the cooler. If you’re the one with motherboard having no RGB header or relevant support then you need to upgrade the motherboard, at least Z270, because this cooler doesn’t even come with any RGB controller, which is a shame. Therefore, if you want to go with Deepcool Gammaxx L240 RGB AIO cooler, then we would suggest you to upgrade before deciding on it, or arrange a third party functional RGB controller and then buy it.
Selling at $101 US Dollar (at the time of this review) on Newegg. The cooler has a fantastic outlook, especially the RGB effects are truly magnificent and get most of your attention. The cooler comes with a bundle of accessories and not to mention the Deepcool’s Fan Hub, in generosity. With being offering full compatibility support on across the sockets (INTEL and AMD), the cooler is future proof across the platforms. Therefore, if you’re looking for All-in-One Liquid Cooler with RGB style out of the box and without compromising on performance, then look no further to it because Gammaxx L240 is one beauty you won’t regret and a great upgrade for your next new build.
Many Thanks to Deepcool for providing product sample for this Review
