This time we tested the Xigmatek Gaia CPU cooler. It has a tower heatsink, three 8 mm direct-touch heatpipes, and a 120 mm fan.

The Gaia seems to be the “bigger brother” of the Xigmatek Loki, which we recently tested. Its box is relatively small and simple, as you can see in Figure 1.

The box contents are shown in Figure 2: heatsink, fan, manuals, thermal compound, and installation hardware. The cooler came with only one fan, but it comes with the hardware necessary to install a second 120 mm fan.

Figure 3 shows the Xigmatek Gaia heatsink.

This cooler is discussed in detail in the following pages.

Figure 4 shows the heatsink from the front. It is simple, with U-shaped heatpipes disposed in one row at each side.

In Figure 5, you see the side of the cooler, where the thick (8 mm) heatpipes are visible. The sides are partially closed by folded fins.

Figure 6 presents the top of the heatsink. Notice the shape of the fins, which have reentrancies for the fan holders in both sides.

Figure 7 reveals the base of the cooler, where the heatpipes touch the CPU directly.

Figure 8 shows the Gaia heatsink with the rubber fan holders installed on one side.

In Figure 9, you can see the PWM fan (with a four-pin connector) that comes with the Gaia.

Figure 10 shows the clips for Intel CPUs installed at the base of the cooler. The Gaia uses the same retention mechanism as the Xigmatek Loki and has the same issue. It doesn’t allow sufficient down force to be applied to the CPU. In order to improve this, we bent the tips of the clips a little upwards.

After installing the clips at the base, you must install the backplate with four screws from the solder side of the motherboard, holding it in place by four thumbnuts, as shown in Figure 11.

Then put the cooler in place and hold it using another four thumbnuts.

The last step is to install the fan, which is not an easy task since the rubber holders are too short and hard; we had to use pliers.

[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 acousticall
y insulated room with no other noise sources, which isn’t the case here.

Error Margin

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

[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.

* Researched at Newegg.com on the day we published this review.[nextpage title=”Conclusions”]

The Xigmatek Gaia seems to be a bigger version of the Xigmatek Loki (sharing its problematic mounting mechanism). However, in our tests, it actually performed worse than the Xigmatek Loki. Maybe the problem is the fan, which is not strong (though it is extremely quiet).

In its present state, the Xigmatek Gaia is a very quiet CPU cooler, but if it had a stronger fan (or fans), and if there was a solution for the low pressure mounting mechanism, it would perform better.
