Super 9 cm

I needed more ventilation on a CPU heatsink, but unfortunately no space (very compact ITX case). So I took this Noctua of the same size as the original. It's one of the Redux family, so it's grey (which is not bad), and packaging limited to 4 screws and nothing more (which is not bad either) and cheaper. Good news, the engines are those of the current generation and not those of the previous one like the previous Redux. Installation in 2 min, the direction of blow and rotation are marked on the frame, and it's good. I close the box, I test... Result much less noise, and much lower temperature even at high load: in short, another Noctua at the top.

Noctua's new PWM is incompatible with older motherboards

Because the NF-B9 fan is detected as faulty by the motherboard due to the Noctua PWM circuitry being incompatible with older motherboards. Same problem with two different NF-B9 fans. It would be nice if the LDLC site would warn its customers of this problem.

        Muffler

        Bought as a replacement for a standard fan (entry level), big acoustic difference!
        Easy to assemble, just needs the rubber fixings to make it perfect (supplied with 4 screws only)
        LDLC: Pro and fast as can be.

        Rather disappointed

        I bought this fan to replace the one on a Synology DS216play. I wanted to make it as quiet as possible. The noise is very slight, but being close to me, it is still a bit noticeable.
        I'm disappointed that I don't notice any difference with this Noctua, despite all the praise I've read about it.

        Good product, just one thing missing

        Very good product, excellent value for money.

        Just one thing missing: this fan is sold as a tower fan, but it fits very well on a CPU heatsink. I think it's a shame that the only fastening systems supplied are rubber pads that can only be used on towers. Good old-fashioned screws and bolts would be nice in the package...

        very good product

        The fan was received promptly, after fitting to replace my original fan, it worked well and was quiet, I recommend it, this site is really top notch.

        silence

        bought from consumer reviews, I am very happy with this product, took it as a replacement for a fan that was not PWN, it allows the motherboard to manage the fan power to cool my CPU.

        Excellent!

        I'm amazed :-) !

        Great fan that I bought on a whim, not too noisy despite its small size but very efficient !
        I use it with a Zalman FX100 Cube processor fan and the two together, it works great: Intel Core i7 6700K processor at less than 23°c on average!

        Another plus: it is 4 pin
