Following up with the review of the NB-eLoop B12-1, I figured I would change things up a bit and go with the other extreme next. The NB-eLoop B12-4 is the high speed king in the Noiseblocker eLoop series, and has an advertised max RPM of 2400! Given how the B12-1 performed, let’s thank Blacknoise again for providing 8 sample units of the B12-4 which will come in handy for statistical accuracy and see how these perform.
Let’s begin as always by taking a look at the specs courtesy the product page:
As we saw before, the product page is common for all the fans in the 120mm eLoop series as is that data sheet which contains more specs for those interested. We see a good 6 year warranty as a result of proprietary technology being implemented here giving a long MTBF of 160,000 hours (at 25 ºC). As we wrap up this section, we also see the list of the eLoop fans telling us that Blacknoise has something for most people in both 3 pin and PWM flavors. Let’s now take a good look at the B12-4 on the next page.
