NoctuaNF-A14 iPPC-2000 PWM, Heavy Duty Cooling Fan, 4-Pin, 2000 RPM (140mm, Black)

I'm really, really impressed with these NF-A14 industrialPPC PWM fans from Noctua. Not only do they have the same excellent 6 warranty and build quality of Noctua's other products, these are black/brown which is a massive improvement over their normal colour scheme of beige/brown.I ended up purchasing 5 of these in total to replace a combination of Silent Wings 3 and EK Vardar 140ER fans in my PC, which has a custom water cooling loop. I was never quite happy with the Silent Wings 3 fans because they didn't push much air and had a rather noticeable whine at full speed and the EK Vardar fans seemed fairly loud at lower RPMs (it was more of a motor tone than the sound of air moving that I could hear).I initially purchased just one Noctua NF-A14 industrialPPC PWM fan just to see how it performed and at what kind of noise levels. However, after installing the fan to one of my radiators and playing around with different fan speeds etc. it became apparent very quickly that this fan moved a lot of air and at 1000 RPM (50%) it was still nearly silent. There simply was no comparison as the EK Vardar at the same RPM was noticeably louder.As a result I purchased another 4 Noctua NF-A14 industrialPPC PWM fans to replace all the fans in my PC (not a cheap investment, I know!). After installing them my computer is nearly silent in normal use with these fans running at about 300-400 rpm. Under heavy load and gaming (with a 1080 in the loop) the fans will run at about 40% and are still very quiet. I've not found I've needed to set them any faster than that to maintain a reasonable delta T.When the fans are set to 100% then they are very loud but it is the sound of air moving. With 5 of them running at 100% it sounds like a vacuum cleaner and is not very pleasant, nor bearable!Unlike the normal beige/brown Noctua fans these do not come with many accessories in the box such as extension cables, splitters, low noise adapters etc.You literally just get fan and 4 screws so as a result the fans do work out quite expensive but I wholeheartedly can say these are the best fans I've ever bought and are worth every penny.

Don't get me wrong the NF-A14 iPPC fans are excellent fans it does not matter if you buy the 2000 or 3000RPM models of these. they will not fail to impress..I have purchased multiple NF-A14's for two gaming rigs I own, they were purchased to replace my Corsair RGB Mag-Lev fans I originally purchased for the machines..Although the Corsair fans look great and do a good job of keeping my system cool at stock speeds, any sort of overclock and they just could not shift enough air to cool my loop in a sensible manner.So I opted to try the Noctua Fan's as everyone else seemed to rate them as really good fans.I have to admit that going forwards, I will only be using Noctua's fans for any builds and my recommendations will be don't do RGB Fan's... Performance over aesthetic's any day of the week for me.ConsThey are as expensive as RGB fan's if not more expensive in some cases.They are noisier than most fans on the market when running 50% speed or higher.They have a slightly higher energy consumption than some other non-RGB fans.At high RPM speeds they are louder than your average fan, so you will here them.Extra expense for buying the coloured Chromax Anti Vibration Pads, if you want to make then fit the theme for your build.3000RPM design may struggle to reach fully speed through 3rd party Fan controllers due to the slightly higher Watt/Amp rating of the fans. Most motherboard fan headers can handle them though, But always check the spec before buying.Pro'sThey are INDUSTRIAL Grade fans.They have an IP rating against liquids and dust.They achieve HIGHER RPM's than most other fans manufactures.They work In both SP and AF jobs.2000RPM models shift enough air for almost all users needs.3000RPM models shift far more air than most people will ever need, but at the expense of noise (obviously).Very well, packaged.Well designed commercial Product available to the public.... what is not to like about that!!!In my opinion who would not like Industrial grade fans with higher performance and design characteristics for longevity in high intensity workload environments for around the same price as aftermarket RGB fans.I just cant see what is not to like about these...

This fan is for those who want the best possible performance without question. This thing can move a serious amount of air and I mean a lot. Noctua have definitely not disappointed in terms of build quality and packaging either, absolutely can't fault them. I already have some regular NF-A14 PWM's and purchased these for a little bit more oomph to finish off my build and they certainly delivered.However for those of you who are picky about how loud your system is beware, although these fans are loud which I actually don't have a problem with since that's to be expected by how much air they can move, my issue is with the PWM motor itself. Over the regular retail model this motor is considerably louder and the clicking from the PWM signal is much more noticeable with this fan (audible from over 2 metres away). Since my rig is standing on my desk next me having that clicking noise constantly in my ear is the reason why i've decided to return them and purchase the regular models instead. If your rig is not so close to you like mine is or you don't have a problem with the clicking noise then I would fully recommend these, they are absolutely incredible fans, for those of you who want a quieter rig however my suggestion would be to buy the regular NF-A14 model instead.
