This time we tested Nexus LOW-7000 R2, a CPU cooler with four heatpipes, a 120 mm fan and with a height of only 2 3/4" (70 mm), making it compatible with SFF cases. But will it perform like "big" coolers?

LOW-7000 R2 box is big but low, showing the cooler main characteristic. The low height is well advertised, but keep in mind that it is not the lowest cooler on market, as Scythe Big Shuriken, for example, is only 2 9/32" (58 mm) high. In the box there is also a small window that shows part of the cooler.

Inside the box we found the cooler, user manual, installation hardware and a tube of gray thermal compound.

In the next pages we will see this cooler in detail.

Nexus LOW-7000 R2 is a horizontal cooler with design similar to other coolers like Scythe Big Shuriken, Thermaltake ISGC-400, SilverStone NT06-E and Noctua NH-C12P. The heatpipes connect the base to a bigger heatsink located over the base but not touching it.

In Figure 4 we have a side view of LOW-7000 R2. Note the fan connector with four pins, which means it has PWM speed control.

In Figure 5 we have a front view from LOW-7000, where we can see the tips from the four heatpipes. We can also see the smaller heatsink, that is attached directly to the base.

In Figure 6 we can see the back side of the cooler, where we can see the position of the heatpipes.

In Figure 7 we have a top view of LOW-7000, where we can see the 120 mm fan.

In Figure 8 we see the base of the cooler. Practically only the heatpipes keep contact with the CPU. The base is not very polished, and thus it has no mirrored surface.

An amazing detail we have not seem before is that the thermal compound syringe comes inside a vacuum-sealed bag. There is also a plastic spreader to help applying the compound.

In Figure 10, you can see the thermal compound tube removed from its bag. A pity that the hard consistency of the compound makes the spreader useless, because the paste keeps "united" and hard to spread. With the pressure from the cooler, however, the thermal compound spreads evenly over the CPU.

In Figure 11 we can see the clip used with AMD socket AM2, AM2+ and AM3 CPUs. The cooler comes with an hexagonal screwdriver to help installing the screws.

In Figure 12, you can see the clips for Intel CPUs (sockets 775, 1156 and 1366). The clips look like the standard ones from Intel. There is also a tool to help installing and removing the cooler from the motherboard.

In Figure 13 we see the Intel clip installed on the cooler base.

In Figure 14 we can see LOW-7000 R2 installed on our motherboard. This was the hardest CPU cooler installation we’ve seen to date – and it doesn’t even have a backplate! With the motherboard inside the case it is impossible to install the cooler and even outside the chassis it was very complicated to install it, because it is hard to access each clip and we needed to use a big amount of force in order to hear the characteristic "click" when pushing each clip.

Actually the pressure applied on each clip is so strong that our motherboard was severely bent, as you can see in Figure 15.

In Figure 16 we see LOW-7000 R2 inside our case.

[nextpage title=”How We Tested”]

We are adopting the following methodology for our CPU cooler reviews.

First, we chose the CPU with the highest TDP (Thermal Design Power) we had available, a Core 2 Extreme QX6850, which has a 130 W TDP. The choice for a CPU with a high TDP is obvious. To measure the efficiency of the tested cooler, we need a processor that gets very hot. This CPU works by default at 3.0 GHz, but we overclocked it to 3.33 GHz, in order to heat it as much as possible.

We took noise and temperature measurements with the CPU idle and under full load. In order to achieve 100% CPU load on the four processing cores we ran Prime95 with the "In-place Large FFTs" option, and three instances of the StressCPU program, all at the same time.

We also compared the reviewed cooler to the Intel stock cooler (with copper base), which comes with the processor we used, and also with some other coolers we have tested using the same methodology.

Temperature measurements were taken with a digital thermometer, with the sensor touching the base of the cooler, and also with the core temperature reading (given by the CPU thermal sensor) from the from the SpeedFan program, using an arithmetic average of the four core temperature readings.

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 video board cooler so it wouldn’t interfere with the results, but this measurement is only for comparative purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

On the tables below you can see our results. We ran the same tests with the coolers shown on below tables. Each test ran with the CPU idle and the with the CPU fully loaded. On BigTyp 14Pro, TMG IA1, NH-U12P and ISGC-300 the tests were done with the fan at full speed and at minimum speed. The other coolers were connected directly to the motherboard and it controls the fan speed based on CPU load level and temperature on PWM models. ISGC-400, iCEAGE Prima Boss and Megahalems Rev. B were tested at minimum speed on idle test and at maximum speed on full load test.

[nextpage title=”Conclusions”]

Nexus LOW-7000 R2 achieved a performance similar to Thermaltake ISGC-400, having a better performance than most cooler with similar design we’ve tested so far (Scythe Big Shuriken, SilverStone NT06-E and Noctua NH-C12P). On the other hand, it presented a performance worse than most tower coolers we tested so far.

It has some problems as well: its noise level is not high but the cooler is not quiet – especially when the advertising on the cooler box says it is a "silent cooler"; its installation is hard; it bends the motherboard; and it is not inexpensive.

So for the average user with a mid-tower case, there is no point in buying this cooler. But if you have an SFF computer and you are looking for a good performance cooler, Nexus LOW-7000 R2 is a good option.
