Review: Top-notch-quality quiet fan and _unbelievably comprehensive_ accessory kit, worth the price of the kit alone! - I bought this fan to replace the noisy one included in an old HDD IDE rack I need to use (the cheap supplied fan has become unbearably noisy due to dust after just a few months of everyday use, unfortunately...). This was the first time I bought a Noctua fan, even if I knew this is one of the highest-quality brands of silent fans, and although some people might think this specific kit is overpriced for a small 40x40x10mm fan, I can assure you that the packaging and the accessories included in it are worth the price of the product alone! The fan itself is almost completely inaudible outside of a case, especially when used at reduced speed, which can be obtained by using the clever low-noise adaptor: a small, inconspicuous cable extension, which goes between the fan connecting cable and the power source connector, and lowers the rotating speed from 4500 to 3700 rpm; by the way, the air flow produced even at reduced speed seems considerable anyway, in my opinion. But the most amazing aspect of this product are the supplied accessories included in this gorgeous kit: apart from some typical, high-quality metal screws, you get professional silicon pins, which can be used to mount the fan screwlessly in order to reduce vibrations, an extension cable, an adaptor cable to convert from 3 to 2 power pins, and the most wonderful adapter of them all: the incredible OmniJoin adaptor set, which includes an extension cable ending with 2 truncated red/black power wires, and four _amazing_ "crimp-like" connectors, which allow you to join the truncated power wires to any other corresponding wires coming from _any_ appropriate fan power source inside the PC, _without even having to remove the insulation from the cables_ (!). Basically, in case you want to attach this fan to any "custom" connecting cable with a connector that does not fit any of the included adaptors, you can just cut the connector off of your available custom power cable, and join the resulting truncated black/red wires with the corresponding truncated ones from the Noctua OmniJoin adapter, "crimping" (pressing) the red/black power wires together using 2 of the 4 omnijoint proprietary connectors with flat-nose pliers (not included). If this sounds complicated, actually I assure you it is not, and everything is explained in extremely clear instructions with detailed figures included in the kit, of course. It is a _very_ clever and professional alternative to just "splicing" power cables together with insulating tape, in my opinion! In the future, I will definitely try more Noctua products like this one, in case I need to attach a fan to a custom power cable, hoping they will work with no problems... (Please note that I have _not_ tried the omnijoint connectors, since I do not need them for my specific connector, luckily.) So, all things considered, in my opinion you _definitely_ get what you pay with this amazing product, and I just hope the fan will last for a long time!
Review: Quieter than a mouses fart!!! - Bought an old 4 bay 1U rackmount NAS from eb** and was shocked how noisy it was. 60+db while building a raid array. So thought not happening and went looking for silent fans, found these and read the reviews and being a Scotsman I was like seriously? for a wee fan like that? and there were 3 system fans and 1 power supply fan. I was aboot greetin. Bought the 4 fans and proceeded to swap them out taking measurements along the way. After replacing the 3 system fans the noise level dropped to a low of 21db and peak of 25db system temp 1degree lower CPU temp 1 degree higher. I then swapped the power supply fan and set the system to rebuilding a raid volume, which is possibly the most intensive thing a NAS is going to do and it is quite happily purring along at a peak of 18 db with a system temp 2 degrees lower and a CPU temp 1 degree higher than factory fitted fans. I should mention that I am using the low noise adaptor cables that come supplied in the fan kit for the 3 system fans. The kit is well supplied with everything you need and gives you options aplenty for extensions and fitting methods. The quality seems to be superb and longevity is backed by their guarantee. I will be buying these fans exclusively from now on and upgrading all fans in my servers. The only nark I would have is the colour! My god it's awful lets have some bright colourful options yellow/black red/black etc, something to indicate that it's a premium high performance fan. Lookswise it definitely needs some cool. Other wise very happy if not skint wee laddie but well worth it.

## Questions & Answers

**Q: How can I use this fan with a 2 pin connection. I’ve just received it only to find my connection is 2 pin. Doh!**
A: Black is (-), red is (+) and yellow is just the probe. You disconnect/cut the yellow one and you have two active wires.

**Q: You replaced Hikvision nvr fan with Noc 40x20. What voltage did u use 12 or 5?**
A: This Noctua fan is rated 5V and this is the voltage to use.

**Q: has anyone tried this in a dan a4 case as a top fan? And would it be worth doing?**
A: I don't know where it would fit at the top of the A4, as the riser cables and psu cable take up the space, there might just be enough space on the GPU side. I have this fan zip-tied to the CPU side panel.

**Q: Good day, when will this item be back in stock again?**
A: it is https://www.amazon.co.uk/gp/offer-listing/B009NQLT0M/ref=dp_olp_new_mbc?ie=UTF8&condition=new

### ⭐⭐⭐⭐⭐ 4x1 Comes with a 2 pin adapter. Ideal for noisy HikVision NVR. Swap is 5/10 min job.
*by H***E on 20 January 2026*

I have an 8k system with 5 cameras. My installers fitted an NVR that had no fan, and I had 2 hard drive fails in 9 months. Hik apparently had many such complaints so decided it was down to heat. My installer swapped the box for the same one, but from October 2025 it’s had a fan in it. And that fan was very noisy. After installation my wife walked in the house and thought I had some fan heater on. I could even hear it over the TV it’s plugged into. Cue some research and buying one of these. It was very easy to swap over took 10 mins top, I basically just unplugged the old one, unscrewed two screws to remove and screwed this one in and plugged in. Made sure I put it in so the air is blowing out, not in. It isn’t obvious from the product description, that it comes with a 3 pin to 2 pin adapter. It does. The third pin is for fan control speed Hik of course hasn’t bothered fitting to the NVR so you just need the 2 power pins. Now it’s much better. Far from silent, but I don’t really notice it now and can’t hear it over the TV. In another design fail Hik not only put in a noisy fan, but have it blowing through perforated holes in the case. To make it quieter I could cut out those perforated holes but that would invalidate warranty of the NVR box but I read it makes another quite big difference if I so chose to do so. I’ve retained the original fan to put back in, in case the NVR ever fails or still trashes hard drives. Another method to make it even quieter would be to plug in the included noise reduction wire, but all that does is limit current to the fan and fan speed, so won’t clear as much warm air- not sure about that given the hard drive failures Hik seem to now agree was caused by excessive heat in an uncooled NVR. Please open your box and check the fan size before buying and placement. Different NVRs have different set ups. The one I had was really easy, some Hik NVRs have fans on the in built power supplies and it gets a bit more complicated as you have to take that out to change. Also some May have differing size fans. Many however will be 4cm by 1cm. I couldn’t not have bought one 2cm in depth as it would not have squeezed in the space. So an easy, very quick and simple solution for me, I am delighted.
