NF-A14 iPPC-3000 PWM, Industrial Heavy Duty Cooling Fan, 4-Pin Connection, 3000 RPM (140mm, Black)

某サイトでよく見る表記のCFM（立法フィート毎分）にするとおよそ158.5CFMとなります。 PCケースにつけたりCPUクーラーのファンとして買いやすく使いやすい140mmファン。 厚さは25mm

回転数(と工業用という肩書に)にひかれて購入しました。 ただ、「工業用」という肩書は、防滴・防塵対応であり、高耐久・長寿命というわけではないようです。 製品の箱の裏面には、下記の情報が記載されております。 IP52対応 ベアリング SSO2 最大回転速度 3000rpm エアフロー 269.3 [m^3/h] 騒音 41.3dB/A 静圧 10.52mm H2O 電圧 6.6W 電流 0.55A MTBF > 150,000h 静圧がかなり高いので、前面のケースファンに使用してもよいかもしれません。 また、かなり音が大きめなので、ファンコントロールが必要だと思います。

Egzoz fan olarak kullanıyorum..tam yük altında biraz ses yapsa da harika hava akışı sağlıyor.

Great performance as expected. Since it is 3k rpm, the high pitch noise will start around 2000 to 2100 and above. Sharing this just in case buyers are considering this product vs noise. I also purchase the 120mm ones and that one is a higher pitch than this when it hits 2000rpm. It can be annoying when you are doing big file encoding for a lengthy period, ambient temperature plays a big role as always. Got these fans for my Threadripper and IceGiant CPU cooler.

Previously, I had an NF-P14 that was pulling double-duty in the middle of my old NH-D14 heatsink (the other fan that was originally with it currently resides in the case's exhaust slot directly aft of the heatsink). This setup worked fine during winter months, but in recent weeks has resulted in intermittent overheating due to the warmth of the room. Rather than restore the heatsink's stock configuration, I opted to simply beef up the heatsink's fan and move the NF-P14 to the case front to supply it; I'd been intending to replace the low-end Cooler Master fan I had there anyway. As both high airflow and high static pressure were needed...this fan was a bit of a no-brainer, even if it is pricy. First off: if you too have an NH-D14, rest assured that this fan will fit. It won't fit as intended (the original mount kit was designed for 120mm-mount fans, the NF-A14 has 140mm mounts), but the heatsink is wide enough to support the fan, and you'll have a bottom overhang for RAM/VRM/etc cooling as with the original NF-P14. Just make sure that there aren't any components extruding from the board that will interfere with the corners. See attached pictures for my super-exotic mounting method. Secondly: despite Noctua's best efforts, this fan is definitely not quiet at higher speeds. Even throttled at 50%, it's quite noticeable, though it's not unbearable. At 100% (which comes to ~2750rpm on my board...something I find slightly worrying actually), as noted in other reviews, it sounds akin to a small vacuum cleaner. If you plan to run it in a gaming PC, make sure you figure out what speed you need for adequate cooling, and stick to that under load. Look up your CPU to find its maximum safe temperature, and set your fan curve to have it kick up to 100% ~5 degrees before that. The fan has PWM control for a reason...use it! There's no reason to deafen yourself under light or no load. Noctua's site lists the minimum speed as 800rpm, however, my board's minimum PWM setting is able to run it at ~400rpm. I wasn't able to test at what point it becomes "silent", but it certainly is at the lower end. I'd expect it to be no louder than the NF-P14 up to 1300rpm, and I never had a problem with that fan's noise. Finally...it's a solid fan. Noctua, in my experience, makes high-quality stuff; this fan is no exception. The price of it made me handle it carefully, but it didn't feel fragile at all. Even the blades, thin as they are, feel solid...I would recommend not putting your fingers anywhere near them while the fan is running. The box is quite nice, but what you actually get is just barely above OEM-level; the fan and wide-thread screws for plastic fans, nothing more. I imagine that the common user would be disappointed by lack of low-noise adapter and/or splitter, but consider: the fan is PWM (a control method far superior to resistive/voltage-based control), and is rated for more than half an amp at full load. It seems to be commonly accepted that motherboard headers shouldn't be loaded above 1 amp, which would be easily exceeded by pairing two of these at full speed on a single header. I would guess that the cost of including a splitter in every box is a drop in the bucket for Noctua, but they chose to not include one to protect themselves if users decided to overload motherboard headers and potentially burn them out. They can't be held responsible if the user finds a splitter elsewhere and decides to risk it, after all. In summary, It's an expensive fan, costing as much as an 8gb stick of DDR3. But for the price you get a fan that performs well and quietly for day to day use, and unlike Noctua's consumer-grade offerings, can go full-out balls-to-the-wall if high levels of static pressure and airflow are needed. It can be made to fit an NH-D14 with the mildest of adaptation, and (according to reviews and Noctua specs) will directly fit an NH-D15. The included accessories are...well, non-existent, but with a proper setup you won't need them anyway.

I've been tinkering with my gaming rig for a while now and recently decided to upgrade my cooling solution. So I grabbed one of these heavy-duty fans, and honestly, it’s been a game changer. Right out of the box, I could feel the quality. It’s solid and not cheap feeling at all. Installation was a breeze. I just popped it in place, plugged it into the motherboard, and that was it. The first thing I noticed was how quiet it is. I mean at 3000 RPM, I expected it to be loud, but it really isn’t. You can barely hear it even when I’m pushing my system hard during those intense gaming sessions. The airflow is impressive. I've been monitoring my CPU temps, and I’m seeing a noticeable drop. When I’m gaming for hours, the temps stay way more stable than before. This fan really moves some air around. If you’re someone who wants to keep your rig cool without turning your room into an air conditioner, this is a solid pick. For the price, I think it’s totally worth it. It’s durable and seems like it'll last a long time. If you’re looking for a reliable cooling solution that performs well and doesn’t break the bank, I’d definitely recommend giving this one a shot. It’s made a big difference for me, and I couldn't be happier with the purchase.

Personally, I’ve never had a PC that felt cold when running, and this fan lets you achieve that. Of course with cooling, you get a very solid performance, and you may also overclock if you’d like. I thought the noise would be an issue, but thankfully, it isn’t. It’s only audible when you first turn on your PC, but I’ve never heard anything while using the PC.
