Today we are reviewing the Xigmatek Aegir CPU cooler, which has a tower heatsink, six U-shaped heatpipes, and a 120 mm fan. Check it out!

The Aegir box has a transparent window in the side, which allows you to see the base of the cooler, as shown in Figure 1.

Figure 1: Package

Figure 2 shows what the box contains: the heatsink, fan, manual, installation hardware, and a small tube of thermal compound.

Figure 3 presents the Xigmatek Aegir heatsink.

This cooler is discussed in detail in the following pages.

Figure 4 reveals the front of the heatsink. Pay attention to the base, because there are four U-shaped heatpipes touching the CPU directly, but there are two more heatpipes just above them, for a total of six heatpipes.

Figure 4: Front view

Figure 5 presents the side of the cooler, which is partially closed by the fins. Here you see only four of the six heatpipes.

Figure 5: Side view

The top of the cooler is shown in Figure 6, where you can see the shape of the fins. Notice that the dents where you attach the fan exist on both sides of the heatsink, which means that the Aegir supports two fans.

Figure 7 shows the base of the cooler. As we mentioned before, four of the six heatpipes touch the CPU directly.

The rubber fan holders are shown in Figure 8.

In Figure 9, you can see the 120 mm fan that comes with the Aegir. It uses a four-pin connector, thus it is compatible with PWM speed control. It also has white LEDs.

Figure 10 shows the backplate used to install the Aegir, with the screws in place.

Figure 10: Backplate

After installing the backplate on the solder side of the motherboard, you need to hold it with four thumbnuts and then install the bars as shown in Figure 11.

Figure 11: Holding mechanism

Next, put the cooler over the CPU and hold it with a third bar, which is screwed into the first ones.

[nextpage title=”How We Tested”]

We tested the cooler with a Core i7-860 CPU (quad-core, 2.8 GHz), which is a socket LGA1156 processor with a 95 W TDP (Thermal Design Power). In order to get higher thermal dissipation, we overclocked it to 3.3 GHz (150 MHz base clock and 22x multiplier), keeping the standard core voltage (Vcore), which was the maximum stable overclock we could make with the stock cooler. Keep in mind that we could have raised the CPU clock more, but to include the stock cooler in our comparison, we needed to use this moderate overclock.

We measured noise and temperature with the CPU idle and under full load. In order to get 100% CPU usage in all threads, 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 the Intel stock cooler with a copper base (included with the CPU), as well as with other coolers. Note that in the past, we tested coolers with a socket LGA775 CPU, and 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 in the next page. Every cooler was tested with the thermal compound that accompanies 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 left panel of the case was open.

The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed 4" (10 cm) from the fan. We turned off the case and video board cooler fans so they wouldn’t interfere with the results. 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 isn’t the case here.

[nextpage title=”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 idle and 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 minimum speed on the idle test and at full speed on the full load test.

In the graph below, at full load 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.

[nextpage title=”Conclusions”]

The Xigmatek Aegir is not as beautiful as the Dark Knight that we reviewed recently. It uses a similar fan and has a similar fin shape, but lacks the black nickel-plating.

However, if we talk about performance, the Aegir is better. Probably thanks to its six heatpipes (the Dark Knight has only three), the Aegir kept our CPU two Celsius degrees colder, reaching a performance only found on high-end air coolers.

Because of its great cooling performance with good noise level, the Xigmatek Aegir CPU cooler receives the Hardware Secrets Golden Award.
