Cooler Master Nepton 240M Review
Category : Watercooling
Published by Marc Büchel on 03.11.14
With the Nepton 240M, Cooler Master has an all-in-one watercooler in its portfolio, that comes with a rather slim radiator and two 120 millimeter fans in the delivery. At a first look the design is looking good while you get a completely black solution. Overall we're now rather curious to find out what this cooler can do in terms of cooling and noise levels.

Today we have the pleasure to check out Cooler Master's Nepton 240M compact liquid cooling system, which, should be compatible with small cases and tighter spaces thanks to its 274 mm long, 27mm slim and 119mm wide radiator. This particular 240mm radiator is slightly slimmer than other 240mm models, since it's only 27mm thick. This helps saving a few millimeters and might allow the installation in cases, which otherwise could not be equipped with an all-in-one watercooler. Apart from that there are kink-resistant FEP tubes, which allow for tight bending radius. Overall this cooler is well made and with its completely black color scheme it's easy to integrate into the design scheme of lots of different builds. The bundle includes two 120mm PWM fans, which are entirely black too. The mounting system supports most, if not all, recent Intel and AMD sockets. When it comes to manufacturing Cooler Master is very proud on the fact they're making every single piece on their own.

As you can see from the pictures above manufacturing quality of the Cooler Master Nepton
240M is
on the level it should be. It's not exceptional but it's still on a decent level for a
90 Euro all-in-one cooler. The radiator itself has been made from aluminium and
there are the usual flat pipes, which increase surface area. The cooling block
features a copper base-plate, which is surprisingly rough. We would like to see
Cooler Master polish the base plate. Thermal compound has not been pre-applied,
which is always a good thing, since the paste delivered in syringes is usually
of higher quality. To be a bit more precise the dimensions of the Nepton 240M are
274 mm x 27 mm x 119mm (LxHxW). According to the specifications
Cooler Master equipped the Nepton 240M with two PWM fans, which spin with
800 to 2400 RPM.

The packaging is quite standard for an all-in-one water cooling system. Alongside the AIO unit you receive two fans, a manual and mounting kits. Cooler Master bundles the Nepton 240M with two mounting kits, one for AMD and one for Intel-based systems, as well as a backplate is used for Intel sockets. The Cooler Master Nepton 240M is even compatible with the old Intel socket LGA775. If anything should break down with the Nepton 240M AIO water cooler you get a warranty that covers such event for a whopping five years.

Installation

|
The installation procedure is quite easy and practical. It is pretty much self explanatory and everything is clearly explained in the manual, so it should not be a problem, even for less experienced users, to mount the Nepton 240M perfectly. The design is not completely tool less as you will still need a screwdriver in order to mount the fans as well as the waterblock. The pressure on the CPU is good and since the base/pump unit comes with a low profile design, there shouldn't be any clearance issues as even tubing can be moved in any direction without the need to worry about blockage or leaking.

To measure the cooling capacity we took temperatures in idle and load with the fans at 7 and 12 V. The idle temperature represents the lowest temperature hit by the processor package after 10 minutes in idle. The load temperature is the highest temperature hit by the processor after one pass of wPrime v2.10. The wPrime test takes 4 minutes and puts load on all 8 threads. Room temperature is at 25°C.

At this point we plugged the fan(s) to the motherboard CPU fan header and let the motherboard take care of fan speeds. In other words the motherboard will adjust the fan speed via PWM signal according to CPU temperature. The idle temperature is the lowest temperature hit by the processor after 10 minutes in idle. The load temperature is the highest temperature hit by the processor after one pass of wPrime v2.10. The wPrime test takes 4 minutes puts load on all 8 threads. Room temperature is 25°C.

Decibel meter (Voltcraft SL-200) has been placed 1 meter away from the cooler. Measurements are conducted in a quiet room, where there are no other noise source. 32 dBA is the lowest we can get in our room. Also here the measurements are conducted at lowest and highest fan speeds in idle and under load respectively.

Conclusion
| General | + | - | |
| Overall, the Cooler Master Nepton 240M is a solid product, which has been kept completely in black and makes it suitable for almost any build. Cooling performance in combination with the two 120mm PWM fans included was a little lower than what we expected. Since this is one of the slimmer all-in-one watercooler, you can mount it in virtually any system that offers space for two 120 millimeter fans next to eachother. |
- PWM - Slim |
- Build quality base plate | |
| Installation | + | - | |
| The installation is simple an pretty straightforward. With two included mounting kits, where one is for Intel and the other for AMD sockets, it should be quite easy even for less experienced users to mount the cooler properly in a heartbeat. This cooler is even compatible with Intels old socket LGA 775. The thermal paste comes in a syringe and is of good quality. |
- Easy and practical
- Compatible Intel and AMD |

| Performance | + | - | |
| The Cooler Master Nepton 240M offers good cooling performanace in all our tests. With the fan driven at 7V and 12V we find the top quarter of our cooler charts and also in PWM mode the cooler ranks in the same range. Comparing the Cooler Master Nepton 240M to other 240mm AiO's the performance is about equal. | - Cooling performances | ||
| Noise Levels | + | - | |
| Our tests show that the fans included in the bundle are silent at 7V and well audible at 12V. Rotation speeds at 7 and 12V are 1'140 and 2'300 rpm. In PWM mode, the fans speeds are rather high, causing the noise level to jump to 40.1 dBA under load conditions. | - Noise level in general | ||
| Recommendation / Price | + | - | |
| Checking Geizhals.eu we find the Nepton 240M listed for 92 Euro, which is in line with the competition. Should you be looking for an all-in-one watercooler that's been kept in black completely, you might want to consider the Nepton 240M from Cooler Master. | - Gaming PC | ||
