NoiseBlockercompatible NB-eLoop Fan B12-PS - 120mm PWM

I wanted a replacement for the extremely loud 140mm NZXT fan on my AIO. NB-eLoop makes a good first impression by being pretty quiet, which is exactly what I wanted. Unfortunately it falls flat in performance. Where my old fan could keep my CPU at around 66-70C, the B14 went as high as 80C. Unacceptable loss of performance in my opinion. Especially for a fan tat is meant to be optimised for water coolers.

Gotta say, I was not really expecting the difference to be this drastic when using these instead of the pre-installed NZXT Aer 120mm fan that came with my NZXT case. Thought the default ones would be great enough but these fans made me change my mind immediately. They are very quiet and also look quite good with my white case I'd say. I'm not really an expert when it comes to the technical stuff relating to their cooling performance but you can look for comparisons on YouTube and decide for yourself like I did anyway. In my case, the cooling performance does not matter as much for my NZXT H500 case, I was more focused on the noise level. I had them set up for a negative air pressure.They came with screws to mount them in case you need them but I used the ones my fans previously had on them. There are also 2 braided fan header cables each differing in length in case you want to do some cable management depending on how far away your mobo headers are.

Bought two of these with a view to quiet ending down my machine, which is getting on for four years old and running an Antec Kuhler 920 rather hot (due to overclocking) leading to some rather noisy stock fans. I popped a couple of these in as replacements, and found the noise much more tolerable, if not utterly silent - because the processor is so warm, the fans are at full speed whenever the computer does anything other than sit idle.Very impressive, really, and I expect these fans to last long enough to run slower (and quieter) when I get around to upgrading the motherboard and CPU in my build - the bearings seem ultra smooth and well built, and the casing seems well protected against dust intrusion. A little pricey, but if you want high pressure/high rpm fans that don't sound like an Airbus on takeoff, these are an excellent choice,

If the fan is unrestricted or used as an exhaust it great and seems to shift a reasonable amount of air from the case However, I also tried turning the fan around and using it with as an intake fan. As the side intake fan on a Cooler Master CM690 II case this causes an awful droning noise at high speed with the wind rushing against holes of this specific case. On other cases I've tried there doesn't seem to be issues.

Fan arrived today, so I can't speak for longevity, or long term quality, but the product seems very sleek and well designed, though a bit plastic-y. The performance of the product however, cannot be called anything less than impressive. At the same RPM as the stock Hyper 212 evo fan it was purchased to replace, it performs consistently at 5-10 celsius colder, at similar, if not quieter volumes. If this fan's lifespan is as good as its performance, I am soon going to replace all of my fans with this one, or others from the same brand.

this is one of the best all purpose fans you can buy and the price really worth as they fantastic and reliable.Performance it's really good and they're very quiet, but if you go for the B14-3 and above this will change as RPM will be higher.If you want something more budget but good as well, try the Fractal Design GP series, Venturi it's very good for airflow but noisy!thanksHighly recommended.

Great fan! Barely any noise, even in my open air case, completely silent below 50% RPM. Really great cooling too, better than the Noctua fans I have and nowhere near as ugly! Only slight downside is it doesn't fully stop when set to 0% like the Noctuas do; it's minimum RPM is 453. not a huge problem though as it's completely silent at that speed I would just prefer it to fully stop like all my other fans do.Overall an excellent fan, would recommend it even over a Noctua for it's silence and cooling performance.

Extremely quiet, excellent build quality, the white version adopts any lighting in the case as well and they look great.I was happy with the included adaptors as well, which helped managing cables
