Aside of the 5 year warranty badge, the packaging of the Nepton 240M emphasizes on cooling performance with an illustration of the actual 240mm radiator and the newly included Silencio FP 120 PWM fan.
A brief description of the features of the Nepton 240M can be found at the back of the box.
Accessories
The accessories included are as below:
- 1 x Warranty information
- 1 x User’s Gude
- 1 x Intel mounting kit
- 1 x AMD mounting kit
- 1 x Y splitter fan adapter
- 1 x Rubber gasket
- 1 x Thermal paste
- 2 x Silencio FP 120 PWM fan
The cable comse sleeved and powers up via a 4-pin fan header.
And we’re now with the main unit of the Nepton 240M, the powerful pump with it’s 240mm radiator.
The radiator has the product name printed on it, a rather premium look we’d say.
Unlike the stiff FEP tubing found on CoolIT made self-contained liquid coolers, Cooler Master went for a pair of FEP tubes with larger diameter that is much easier to bend but kink-free.
The sealed cap, it is possible to replace the coolant but it is not advised to do so.
Here’s why – any action to tamper or remove the seal will void your warranty.
The aluminum fins on the 240mm radiator to dissipate heat from the liquid inside the loop.
This appears to be the very same pump from the existing Nepton(s), featuring long life-span up to 70,000 hours and excellent water flow up to 120 Litre per hour.
Below the pump is the copper plate to transfer heat from your CPU to the liquid that passes through the micro channels in the copper plate. Cooler Master claimed that they’ve made the skived fin area to be around 4.5 times larger than what their competitor can offer to the end users.
The included rubber gasket is supposed to be placed in between the radiator and fans to absorb vibration to achieve near silent operation.
The mounting kit is very simple and straightforward, all we needed to do behind the motherboard is to secure the screws with the included plastic clips to its designated socket size and place it at the back of the motherboard where the processor is.
Upon placing the backplate at the right position, secure the screws with the included stand offs – this can be done easily by hand.
The final step is to secure the pump firmly and you’re good to go. The installation process was easy but it’ll be even easier if thumb screws were used as mounting screws for the pump.
Performance Test
Test Bench Configuration | |
CPU Cooler | Cooler Master Nepton 240M |
CPU | Intel Core i7 4770k |
Graphics Card | ASUS GTX 680 DirectCU II OC |
Memory | Corsair Vengeance Pro 4GB x 2 |
Primary Hard Drive | Intel 520 Series 240GB |
Power Supply | SilverStone Strider Plus 600W |
Chassis | Vector Bench Case |
We fired up a CPU stress test with Prime95 with the option ‘In-place large FFTs’ for maximum heat output, under room temperature of 28ºC. We’ve also included results for various CPU coolers that we’ve tested with the same configuration as a comparison for the Cooler Master Nepton 240M.
It turns out that the Nepton 240M performed the best among the high end coolers we’ve tested, peaking only at 66°C for an Intel i7 4770K overclocked to 4.4GHz. Beating both Corsair H100i and Corsair H100 in the category of 240mm self-contained liquid coolers. This is quite an achievement, but beating the Noctua NH-D15 is really something as there aren’t many self-contained liquid coolers is even able to perform as good as the NH-D15.
Our Verdict
- Outstanding performance
- Reasonably good value for money
- Easy to install
- The Silencio FP 120 PWM fans stays quiet even at full speed
- There’s option to replace the coolant, but doing so will void the warranty

Hi there, any local stores selling this now?
Hi yazid, it's not available at any local stores yet but it's coming pretty soon. 😛
