Cooler Master Hyper 612 PWM CPU Cooler Review

[nextpage title=”Introduction”]

The Cooler Master Hyper 612 PWM is a huge CPU cooler with a tower heatsink and six heatpipes. It comes with one 120 mm fan, but supports up to two fans.

The Hyper 612 PWM big box is shown in Figure 1.

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

This cooler is discussed in detail in the following pages.

Figure 3 shows the cooler from the front. Here you can see the semitransparent front fan.

In Figure 5, you see the side of the heatsink, which is very large. Notice that only a very small part of the heatsink side is closed.

Figure 6 reveals the rear of the heatsink. Here, you can install a second fan, using the included frames.

On the top of the cooler, there is a black aluminum part with the Cooler Master logo that allows you to see the tips of the well-spaced heatpipes.

Figure 8 reveals the six heatpipes near the base of the cooler. There is an auxiliary heatsink over the base.

The base of the cooler, which is a solid copper block, is shown in Figure 9. This base is smooth but does not have a mirror-like aspect.

The fan is easy to remove, thanks to the plastic frames to which it is attached. Figure 10 shows the heatsink after removing the fan.

In Figure 11, you can see the fan that comes with the Hyper 612 PWM. As the name of the product suggests, the fan is a PWM model, thus having four pins in the connector. There are four rubber pads which help absorb vibrations.

[nextpage title=”Installation”]

In order to install the Hyper 612 PWM on our Intel CPU, the first step was to attach the clips shown in Figure 12 to the base of the cooler.

After that, all you need to do is put the cooler over the CPU, place the backplate on the solder side of the motherboard, and then screw four nuts, shown in Figure 13, to secure the cooler in place.

[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 measureme
nts 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.

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.

[nextpage title=”Conclusions”]

The Cooler Master Hyper 612 PWM looks like a great cooler and, this time, appearances were not deceptive. It is a great cooler indeed, with a terrific performance and a good noise level.

We couldn’t find any issues in this cooler except for its huge size, which can be a problem with narrow cases (it is 163 mm tall) or with memory modules with tall heatsinks (more than 42 mm). However, it is a problem shared by most high-end air coolers.

By its excellent performance, we are giving the Cooler Master Hyper 612 PWM the Hardware Secrets Golden Award.
