Nexus 120mm Real Silent

We tested fans from the Dutch firm Nexus Technology a year ago and found the Basic model very good, praising it as one of the best in that test. In my today’s test session the company is represented by the 120mm Real Silent model that comes in two colors: with white (D12SL-12WL) and blue (D12SL-12BL) highlighting.

The fans are sealed into transparent plastic blister wraps and thus can be easily seen through the packaging. There is also some useful information there.

 

Included with each fan are a PATA power adapter and four silicone pins.

The impeller shape and the frame resemble the Nexus PWM (D12SL-12 PWM) which, unlike the Basic model, did not do especially well in our earlier tests.

 

By the way, we wrote in that earlier review that that fan would look good with highlighting, and now Nexus really offers highlighting in two colors! The fan’s impeller is 112 millimeters in diameter. Three of the spokes are 4 millimeters wide; the cable spoke is 8 millimeters wide. The rotor is 45 millimeters in diameter. The fan weighs a mere 123 grams.

The impeller is the same as in the above-mentioned Nexus PWM:

But its speed is now 1000 RPM. The manufacturer promises an air flow of 36.87 CFM at a noise level of 18 dBA.

The sticker on the rotor conceals an electromotor and a sleeve bearing with an unspecified service life.

Judging by the specs, these fans can work at a voltage of 6.5 to 13.8 volts and start up at 7 volts. However, both samples had a start-up voltage of 9.9 volts in my tests, which is one of the worst results in this review. On the other hand, they are rather economical despite their highlighting, consuming only 1.55 watts rather than the specified 3.6 watts. The 3-wire sleeveless cable of these fans is 400 millimeters long.

There are LEDs in the four corners of each fan:

Both types of highlighting look very beautiful:

 

Now let’s see how good these fans are in terms of air flow and noisiness:

The highlighted Nexus PWM fans are very high-quality products. Although they do not make it into the top four, they should be appreciated by modders as well as by any user who prefers quiet computers. These fans are quiet until 980 RPM (which is very close to their maximum speed) and may only disturb you with the bright color of their highlighting but not with their noise.
