Today we are testing the Thermalright Macho, an enormous CPU cooler with six heatpipes and one 140 mm fan. Check it out!

Figure 1: Package

Figure 2 shows the contents of the box: heatsink, fan, a small bag of thermal compound, manual, case sticker, and installation hardware.

Figure 3 displays the Thermalright Macho heatsink.

This cooler is discussed in detail in the following pages.

Figure 4 illustrates the front of the heatsink. The first thing we noticed was the big gap between the fins, which makes this heatsink suitable for low pressure fans.

Figure 4: Front view

Figure 5 reveals the side of the large heatsink. Notice that the heatsink is shifted from the base, which allows it to clear the memory sockets’ airspace.

Figure 5: Side view

The rear side of the cooler is presented in Figure 6. The Macho heatsink supports a second fan, but the product doesn’t come with the wire clips needed to install one.

Figure 6: Rear view

In Figure 7, you can see the top of the heatsink. The fins have holes with folded tabs, which help to improve the cooling performance.

The base of the cooler is seen in Figure 8. Notice that the six copper heatpipes don’t touch the CPU directly; they are soldered to a nickel-plated copper base with near-mirrored finishing.

Figure 8: Base

Figure 9 shows the detail of the heatpipes curves.

The 140 mm PWM fan is shown in Figure 10.

Figure 10: Fan

In Figure 11, you can see the Macho with the fan installed. The cooler comes with four rubber pads to be glued on the fan in order to absorb vibrations.

[nextpage title=”Installation”]

Figure 12 reveals the backplate used to install the Macho. You must install the screws at the backplate in the holes matching the socket used by your CPU.

Figure 12: Backplate

After putting the backplate on the solder side of the motherboard, you need to attach four thumbnuts from the component side, and then install a metal frame over them, as shown in Figure 13.

Figure 13: Frame installed

After installing the frame, put the cooler over the CPU and hold it in place, screwing the transversal holder to the frame. The “hole” in the heatsink is needed to insert a Phillips screwdriver (you will need a long one) that reaches the second screw. If you don’t have a long screwdriver, you can attach this screw with the wrench that comes with the cooler. However, you will have to remove the motherboard from the case in order to reach it.

The last step, installing the fan, is an easy task. You can see it in place in Figure 15.

[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.

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

Like the Zalman CNPS12X and the Akasa Venom Voodoo, the Thermalright Macho is big but quiet. As is the case with both the other coolers, it seems to be focused more on silence than on ultimate performance, presenting a good but not extreme cooling performance.

The Thermalright Macho is one of the quietest coolers we tested so far, showing at the same time a good cooling performance and a suitable price tag. Because of that, this gentle giant receives the Hardware Secrets Silver Award.
