The Thor’s Hammer is a CPU cooler from Xigmatek with a tower heatsink, seven heatpipes, and supports one or two 120 mm fans. Let’s test it.

The Xigmatek Thor’s Hammer box is nice, with colorful holographic reflections. It has transparent openings which allow you to see the base of the cooler.

Figure 1: Package

The box contents are shown in Figure 2: the Thor’s Hammer heatsink, manual, thermal compound, and installation hardware. This cooler doesn’t come with fans, but it supports one or two 120 mm fans.

This cooler is discussed in detail in the following pages.

Figure 3 shows the heatsink from the front. The aluminum fins and the copper heatpipes are both nickel-plated for a beautiful dark look.

Figure 4: Front view

In Figure 5, you see the side of the heatsink, which is very large.

Figure 6 reveals the top of the heatsink. The fins have unusual shapes, all of them with a hole at the center. Only the top fin is spliced in two; the other ones are single pieces.

Figure 7 reveals the heatpipes near the base of the cooler. There are four 8 mm heatpipes at the bottom of the base, and three 6 mm heatpipes on a second layer.

Figure 7: Heatpipes

The base of the cooler is shown in Figure 8, where you can see the four 8 mm heatpipes that keep direct contact with the CPU.

Figure 9 shows the rubber fan holders in place. As this cooler doesn’t come with a fan, we will use in our test the fan that came with the Aegir CPU cooler, also from Xigmatek.

Figure 10 shows the clip for use with AMD processors at the left. In this case, the cooler will be installed in the motherboard frame. The backplate for Intel systems is at the right.

Figure 10: AMD clip and Intel backplate

In order to install the Thor’s Hammer on our CPU, the first step was to attach the clips shown in Figure 11 to the base of the cooler.

Figure 11: Clip installed

After that, we put the backplate on the solder side of the motherboard, placed the cooler over the CPU, and then screwed four spring-loaded screws to secure the cooler in place. Due to the shape of the fins, two of those screws were easily attached, but the other two took a lot of time to be attached.

The last step is to install the fan, as you can see in Figure 13.

[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.< /p>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.

The Thor’s Hammer is a beautiful CPU cooler. With its nickel-plated black metallic look and its fancy fin design, it is very eye-catching.

But appearance is not everything. Although its performance wasn’t bad at all, it performed a little worse than its “brothers,” Dark Knight and Aegir. And as it is more expensive than both (and you will have to buy a good fan, in addition), there is no point in buying it unless you really love its design.
