I bought this as a replacement for the one in my Netgear rackmounted switch, which had suddenly gone very noisy. As the original fan was only two-pin, yet this is a three-pin, I expected that I would need to cut-and-shut with the original connector. However, I was pleasantly surprised to find a handy little adapter and some small gel-filled Scotchlok connectors. I still had to cut the connector (and its wires) from the old fan, but then it was just a moment's work to join it to the adapter and have everything ready to plug in. No solder, nor heatshrink required. I used two of the included anti-vibration mounts to fit it in place, rather than the screws. They were a little fiddly, but anything that helps reduce vibration can only be a good thing. That said, it's incredibly quiet for a 40mm fan, so I doubt vibration would be much of an issue anyway. So, not the cheapest fan, but worth if for the peace and quiet along with what will hopefully be, a long service life.
Fantastic!! I put this in my Marshall JMT615 Valve Amp, as there is is known over heating issue with these due to heat rising from the power valves and into to the chassis head containing the capacitors, resistors, wiring, pcb, etc. I placed an aluminium plate between the power valves and the head housing the capacitors, etc. This fan then draws heat from the head housing down onto the aluminium plate (not the valves), keeping the enclosure relatively cool, but allowing the valves to get as hot as they need to.
Anyway - it's super quiet - If I place my ear close to the amp I can only just hear it with the amp off. If you weren't listening for it, you wouldn't notice it at all. With the amp on I can't hear it at all.
I used this to replace a normal 40x10mm fan that put out the usual fan noise and you easily hear that one, and was unbearable. The accessories supplied with the fan were really useful for replacing this. Basically converting this 3 pin fan to my 2 pin supply.
This is one of the nicest computer fans I have encountered. It came with full mounting kit including anti-vibration mounts, an extension cord, an adapter and Skotchlok connectors (including 2 spare) to connect to existing wiring. The fan itself has rubber inserts in the frame which would further dampen vibration. It has a 6 year warranty and 150,000 hours mtbf and has a sealed bearing to exclude dust. It is very quiet.
I'm using it to cool a Raspberry Pi 4. It moves quite a lot of air so I'm certain it will make a good job of cooling.
I bought this to replace a 2-pin fan on my DVR. The first thing I was impressed with when unboxing was that there was an Omnijoin Adapter Set included. For those not in the know they are little electric joints which I could use to change the fitted 3-pin plug with my original 2-pin. This is quite simple and you just leave the yellow wire disconnected. Replacing the existing fan was a doddle and I use the included grommet screws instead of the original bolts. The DVR was back up and running in minutes. The fan itself is extremely quiet, but on the downside, the design of my DVR case is somewhat wanting and therefore, once everything was re-assembled there was what you could call some slight wind noise where the air is trying to escape through too small a gap. However, compared to the replaced fan it is a real beauty and worth every penny.
Bought 3 to replace aging fans in a Netgear GS724TP POE switch which were REALLY noisy. The size and shape are identical to the original fans so mechanically very easy to fit. The pinout is different, but thanks to the connectors used on this fan, it's easy to swap then around, just use a very small screwdriver to release the locking tab on the connector pin and slide out. Once all installed the noise is probably less than a quarter of the original.
The packaging and supplied accessories are excellent with mounting and cable adapters, plus a couple of different inline resistors to slow the fans in case you need them even quieter.
These fans are pricey, but they seem like quality items which is worth the extra when installing in a network switch.
Amazing how much difference a great product with excellent design has to fit these in very tight spaces (1U rack server)
Noctua has a very strong reputation and for VERY good reason, they are the best performing (by a LONG LONG way) and least noisy fans I've ever used.
I purchased (from amazon as well) I cheap set of 4 fans. One only lasted 2 days, the others, lasted about a month. These are double the price, however, they are 10 times worth it!! I cen feel and hear the quality, design and attention to detail.
like the rubberised attachments. Great idea!!
Simple things that just make fitting these a total doddle!! Even for someone with bear paws for hands, like myself.
Bought two of these to replace the Delta fans in a Netgear rackmount switch. Great choice. Airflow is excellent, no blue smoke coming out of my switch (keep reading tho), and the fans came with plenty of accessories and adapters. Just remember that not every 3-pin fan connector uses the same pinout as these Noctua fans! I connected one of these straight into my switch and smoke started coming out of it. It's still working, though. Noise level is insanely low, but remember that vibrations still transfer through the fan's stator into the case, which can make an annoying high-pitched noise if pressed against something else.
I'm not using it in a PC but as a very much quieter additional fan in a set-top box to stir the air past the very hot jungle chip and the hard drive whenever the 12V line to the hard drive is awake. The box as a whole can easily lose the heat of these two devices.
The included adaptor leads allow me to run it at a lower speed, saving power and again less noise.
The supplied kit of bits is very useful, allowing a lot of flexibility in mounting and connecting.
Used to reduce the noise level in my USG-4 Pro as it’s in a home environment.
Very well made and did the job perfectly. I used the ultra low noise adapters included and they’re almost inaudible but still nice enough air to cool effectively.
My only gripe would be the price which I think could probably come down if they didn’t include so much fancy packaging and materials. They’re only fans for Pete’s sake and by colouring them beige and brown you’re kinda p*ssing in the wind from the start really.
Used these to replace the stock fans in a Cisco SG500-24P, which sounded like a jet engine was about take off. The Noctua's are 1000x quieter and also seem to push out more air. The Cisco switch doesn't like the fact it's got more efficient fans installed and furiously blinks it's fan LED to indicate it's not happy; doesn't bother me though!
Would be great if Noctua offered the fans with just the customisable tails and 3M connectors; didn't need any of the other stuff and would probably make the fans cheaper for the consumer.
