Introduction

Hardware Secrets Silver Award

Let´s test the Deepcool Neptwin, a CPU cooler with two tower heatsinks, six heatpipes, and two 120 mm fans. Check it out!

The Neptwin comes in a tall cardboard box, as seen in Figure 1.

Figure 2 shows the contents of the box: heatsink, fans, a small tube of thermal compound, manuals, fan connector splitter, and installation hardware. The Neptwin comes with two fans, but there are wire holders for up to three fans.

Figure 4 illustrates the front of the heatsink. The six heatpipes are distributed at the sides of the heatsink, which is the area that receives the most airflow.

Figure 7 illustrates the base of the cooler. The heatpipes don’t touch the CPU directly; there is a nickel-plated copper plate at the base, soldered to the heatpipes. The base surface is perfectly mirrored.

Figure 8 reveals the 120 mm fans that come with the reviewed cooler. One of them supports PWM speed control, while the other one has a three-pin connector, which means it is not PWM compatible.

Installation

The first step of the installation of the Neptwin is to prepare the backplate. You must install the four screws in the holes that match your CPU socket, holding it in place with rubber pieces that also act as insulators. Figure 11 shows the backplate with the screws installed in the socket LGA1155 position.

Locate the backplate in the solder side of the motherboard, install four plastic spacers, and then the metal bars shown in Figure 12, securing them with four nuts.

Put the cooler in, holding it with a transversal bar. Notice that the first fan was located over all of our memory modules.

The last step is to install the second fan, as shown in Figure 14.

How We Tested

We tested the cooler with a Core i5-2500K CPU (quad-core, 3.3 GHz), which is a socket LGA1155 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 4.0 GHz (100 MHz base clock and x40 multiplier), with 1.3 V core voltage (Vcore). This CPU was able to reach 4.8 GHz with its default core voltage, but at this setting, the processor enters thermal throttling when using mainstream coolers, reducing the clock and thus the thermal dissipation. This could interfere with the temperature readings, so we chose to maintain a moderate overclocking.

We measured noise and temperature with the CPU under full load. In order to get 100% CPU usage in all cores, we ran Prime 95 25.11 with the “In-place Large FFTs” option. (In this version, the software uses all available threads.)

We compared the tested cooler to other coolers we already tested, and to the stock cooler that comes with the Core i5-2500K CPU. Note that the results cannot be compared to measures taken on a different hardware configuration, so we retested some “old” coolers with this new methodology. This means you can find different values in older reviews than the values you will read on the next page. Every cooler was tested with the thermal compound that comes with it.

Room temperature measurements were taken with a digital thermometer. The core temperature was read with the SpeedFan program (available from the CPU thermal sensors), using an arithmetic average of the core temperature readings.

During the tests, the panels of the computer case were closed. The front and rear case fans were spinning at minimum speed in order to simulate the “normal” cooler use on a well-ventilated case. We assume that is the common setup used by a cooling enthusiast or overclocker.

The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed near the top opening of the case. This measurement is only for comparison purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

Error Margin

We adopted a 2°C error margin, meaning temperature differences below 2°C are considered irrelevant.

Our Tests

The table below presents the results of our measurements. We repeated the same test on all coolers listed below. Each measurement was taken with the CPU at full load. In the models with a fan supporting PWM, the motherboard controlled the fan speed according to core load and temperature. On coolers with an integrated fan controller, the fan was set at the full speed.

In the graph below, you can see how many degrees Celsius hotter the CPU core is than the air outside the case. The lower this difference, the better is the performance of the cooler.

Conclusions

The Deepcool Neptwin is a very well-made, high-quality cooler. It is beautiful and seems to be very sturdy. It has good cooling performance combined with quiet operation.

The Neptwin also has a flexible installation. You can install it with two fans as we did, but you can install only one fan at the middle (if you experience compatibility issues with memory modules), with one fan at the middle and the other one at the rear side, or even with three fans. You can also, of course, replace the stock fans for more powerful ones (sacrificing the silence for better performance).

Because of its good look, quality, low noise level, and performance, the Deepcool Neptwin gets the Hardware Secrets Silver Award.
