Noiseblocker NB-eLoop B12-4 Review

The accessories are some mounting screws and extension cables.

The testing setup
For testing the fans I'm using the RAM and fan test bench form this post. For temperature testing I run IBT and measure temperatures using AMD overdrive. I do the noise testing a room with ambient noise of 25dB. I first run the fan on it's own stading on a matress and then mounted to a H100 radiator. To measure the noise level I'm using the Sound Meter app on my Gsmart Mika M2 placed about 15cm away(otherwise I get no noise pickup).
These are the CPU power settings:
Clock = 4.5Ghz
VCC = 1.525 High LLC
VNB = 1.2 medium LLC

Fan Specs
Dimensions: 120 x 120 x 25 mm

RPM: 2400
Power Draw: 0.32A @ 12V
Noise level(lower is better): 53dB
Noise level radiator(lower is better): 51dB
CPU thermal margin IBT load(higher is better): 16.62C° (ambient 25-27C°)

As you probably noticed I have upgraded my testing procedure. This change is getting applied to the older reviews as well and is in the main fan review database.
Also please take some time and checkout my sponsor Silicon Lottery. They sell prebinned i7 CPUs. Meaning that you can buy a chip from them knowing how high it will overclock. No more getting chips that don't OC properly.
