ARCTIC P14 PWM PST (5 Pack) - 140 mm Case Fan with PWM Sharing Technology (PST), Pressure-optimised, Computer, Fan Speed: 200-1700 RPM - Black

I couldn't be happier with the ARCTIC P14 PWM PST 140mm case fans! These fans offer exceptional airflow and pressure optimization, making them perfect for both case ventilation and radiator cooling. With a PWM range of 200-1700 RPM, they adapt efficiently to system demands while remaining whisper-quiet, even under load.The PWM Sharing Technology (PST) is a game-changer—it allows multiple fans to be controlled via a single signal, reducing cable clutter and ensuring consistent cooling performance. The build quality is fantastic, with sturdy materials that feel durable and long-lasting.Installation was a breeze, and the fans run incredibly silent, even at higher RPMs. The pressure-optimized blade design enhances static pressure, making them an ideal choice for restrictive airflow setups like radiators or mesh-front cases.If you're looking for high-quality, efficient, and quiet cooling solutions, this 5-pack is an absolute steal. Highly recommended for gamers, PC builders, and enthusiasts who want the best balance of performance and noise reduction!

Move tons of air at low silent speeds.

These fans are a German design and feature a very smooth bearing that Arctic developed. I have noticed that when I power the system off these fans coast down over a much longer period than other non-Arctic fans in the case (the AIO cooler I used is a different brand). That is an indication that the Arctic fans (this model, at least) should have a pretty decent MTBF. They move a lot of air, I pretty much don’t hear them, and I doubt I’ll ever need to replace them before the system itself becomes obsolete.These fans plugged directly into the motherboard fan headers and effortlessly interfaced with the motherboard fan control (I used an ASUS motherboard, but I expect the fan headers follow an industry standard - so Gigabyte, MSI, ASRock… brand shouldn’t matter for this feature). These are non-RGB, so one need not be concerned with RGB control. Personally, I was concerned that too much RGB would make my system more clown car than functional. So interface was plug and play - I literally did not need to do anything else. BIOS adjustments will work through the motherboard so customization of the fan control is straight forward. These should just go along with any configuration a user sets up. Simply leaving the BIOS at factory settings is also an option - the point being; install to the frame, plug into the board, and no other action is required on the fan itself.Installation was pretty easy as well. These use an ABS plastic frame in their design - its durable, yet has some surface pliability. The installation is simply to use the provided screws which will cut their own threads into the plastic. So, while installation is simple, one needs to take care not to over-torque - these are not steel. One downside of this is that a certain amount of care and dexterity is required to maintain a straight line while initiating the threads or the screw can end up a little crooked. Not a big deal, but just worth noting. In theory one may be concerned that over time the screws would work loose from vibration and the ABS would no longer be able to accept sufficient torque. But these fans are so well balanced that their operation is glass-smooth. So I doubt vibration will be a factor. Should I discover this to change however, I’ll revisit this post. For now, these fans have everything where it counts; simplicity, effectiveness, silence and presumed service longevity. I’m pretty happy with them.And all at a bargain price, too.

Ok, so installed these in my Helios case and all is well, except the rear exhaust fan is starting/made a rattling noise since it was installed. (Using a Noctua Fan hub atm since I didn't want to use too many extensions to get fan wires where they needed to be) Will probably swap the rear fan with the extra (case uses 4 140mm fans, 3 front intake & 1 rear exhaust) and see if that one is also rattling a bit. Will probably be a bit on that since I don't want to pop zip ties on the rear of the case until I know whether I want to add ARGB strips to the case (and whether that'll force me to put an ARGB hub somewhere)OVERALL: I'd say these are vastly superior to the 140mm 3pin fans that my case came with and definitely seem a bit quieter and move more air. Only thing may be QC of parts since that rear fan occasionally rattle at 700/800RPM (according to mobo) and definitely rattles at full speed (boot/no PWM signal detected)Side note: the 3 pin 140mm fans that the Helios came with were probably a bit thinner, or these are a bit thicker, either way, the front fan bracket had to be finessed (bent some holders) to go in with these fans.UPDATE: No actually, the rattle was getting annoying and appearing at lower RPMs. Swapped for the 5th fan in the box and it's running nice and quiet now. So only the one fan had a bad hub/improper balance(?)

Got one of axis fan out of the 5 seems good

smooth and quiet

Can't beat the value of the 5 pack. Using all five in a build as case fans. Three intake and two exhaust set up to provide a slight positive case pressure. Very quiet with the proper fan curve. The 140mm version moves a lot of air without having to run them at 80+ % RPMs which keeps them very quiet. Highly recommend these fans for the price point and quality. They look good also if you are not into the RGB bling kind of thing. I am not.

I like to purchase these fans due to their quiet operation, PWM connection/control and quality. They come with the PWM four-pin connectors so the motherboard can fully adjust the fan for optimal performance. While the materials are the standard plastic used for fans, I have never had a fin break on one of these fans like the fans that come with PC cases do after hours of operations. I always remove the OEM fans and replace with these and never have I been disappointed.
