NoctuaIndustrial PPC-2000 IP67 PWM 140mm, NF-A14_INDUSTRIALPPC-2000_IP67 (140mm)

Bought 2 of these and they are my first pair of noctuas.Put them in the front of my 750d airflow edition case, as I believe I needed something with a little better static pressure due to the filter, replacing two Corsair AF140 Quiet LED fans. The difference is noticeable. My case temps, playing The Witcher 3 using an MSI 980 ti, dropped 5 degrees Fahrenheit. 80-81F from 86-87F.Using a fan controller, I put the noctuas at 70% fan speed (about 1400 rpms) compared to Corsair 140's which were at 100% fan speed (1200 rpm). At 100% though (2000 rpm) the noctuas are loud, so I prefer keeping them <1500 rpm. I can only imagine what the 3000 rpm version sounds like which is why I didn't go for those. I love these fans and will buy more in the future. They are expensive but I believe the price is justified. Just wish they made some LED versions for aesthetics.

Sweet fans. I bought a 140mm IP67 for use in a large indoor humidifier. They really move air. Not all that loud either.

Thanks!

I was absolutely BLOWN AWAY by how quiet these fans were. I bought them as a replacement for the incredibly noisy stock fans on my Corsair H115i. They fit nicely in my NZXT S340 at the front with the radiator in place - everything screwed in fine. Seriously though, the difference is night and day. I was getting sick of my PC sounding like a car revving when it started hitting the threshold for it to increase the fan speed. These fans do generate some noise at higher RPMs, but it's a consistent increase in noise, and they're still fairly quiet when going full pelt. I really couldn't be happier with them.

Firstly, I purchased the Noctua Industrialppc as a replacement Exhaust Fan for my HAF 932 Advanced Case.Nothing wrong with the current case fan, just felt like a change and the new Industrialppc and Redux fans got my eye.The packaging is superb and it comes in a presentation box - but as most of Noctua's products are well presented, wasn't too surprised. The Fan is as seen - Black, with Brown Rubber corners and the cable is completely sleeved all the way to the header (good quality).In the box are 4 silver screws to mount the Fan - and that's it.Just a note to say that I have been fortunate enough in the past to own Noctua fans and from recollection, they tend to add a small number of accessories such as cable extensions, splitters, etc.However, this was "Not" the case with this fan (which was a little disappointing)..Anyhow, installed the fan with no problems and attached to the CHA_FAN2 on my Asus Sabertooth 990FX R2.0 motherboard.Started up the computer and got a shock - it was LOUD!!Up to this point, my PC was very silent - PSU Eco Setting on, HAF 932 with 3 large fans running at 700rpm and <20 dBA and a Noctua NH-D15 with 2 140mm fans running at 700rpm.Thus, completely silent.So got a shock !! Went into Windows and the Fan continued to roar and ran at full throttle (1968+ RPM). It sounded like a Hoover and was evident and distracting. The positive is that it moved a HUGE amount of air. It actually blew my 140mm Dust cover off and you could feel the air on your hand holding it a foot away from the Fan. Stunning..On checking my temps, it reduced my CPU Core and Socket temps by 1-2 degress (by just adding that one fan). However, it was short lived as I just couldn't cope with that noise.My assumption had been that due to the fact the Fan was a 4-pin PWM, the Motherboard would regulate it's speed based on the current temperatures. That was not the case.It turns out (after much research) that my motherboard has only 2 true PWM headers controlled on the motherboard and they are CPU_FAN and CPU_OPT1 (which were being used by my Noctua NH-D15).Not Noctua's fault - my error and left me disappointed with my ASUS motherboard.I was eventually able to resolve the issue by changing the Fan to the CHA_FAN4 on the motherboard, then going into the BIOS and enabling Q-Fan Control on CHA_FAN4 and setting it to Manual.This then allowed me to control the Fan speed via the Asus Suite II software on Windows and as we currently speak, I have manually adjusted the speed to 55% and it's running silently at 1200RPM.At 55% and running at 1200rpm, it barely audible and still shifting a lot of hot air out the back of the case.In conclusion - if you buy this fan you are getting -1. A high quality fan.2. Great Warranty covered by fantastic after-sales service,3. ability to exhaust a LOT of air as needed,4. ability to control the speed manually via motherboard (or fan controller),5. cleaner case innards due to the fact that the FAN is dust free (special coating) and6. Its water resistant (but hopefully that's not something you will need to test).Only slight issue is the price - at £25, it's a little pricey.But I love this fan and feel the quality and it's ability justifies the higher price tag.

These fans are excellent!I recently installed one after seeing it being used in the Asus Rog Ryujin liquid cooler. I have to say these fans have great strength and the black and brown profile fits in any build. ( The brown grommets can be removed too and swapped for other colours which you need to buy)The only problem is they can be quite noisy at the higher RPMs however this is easily fixable.Overall, very happy with these fans and will buy more in the future. I recommend getting the Phanteks halo fan cover which turns any fan into a mesmerising rgb haven haha.

Great fan and nice and powerful, airflow is great at full speed if you can tolerate the noise. This fan is designed for high airflow and pressure so noise is the sacrifice, dont buy if you want a silent pc.

Excellent fans, never used noctua before, cannot believe the difference in the air being pulled out of my case compared to the ones it replaced.
