ARCTIC 140 mm Case Fan with PWM Sharing Technology (PST), Pressure-optimised, Very Quiet Motor, Computer, Fan Speed: 200-1700 RPM

This is one of those rare products that is both amazing AND cheap.I'm using 3 of these P14s as intake fans in my Fractal Design Meshify 2 case. My system is a 3090ti, i9 12900k, and 6000MHz DDR5 RAM. Needless to say, my rig produces a TON of heat.Originally, I purchased 3 120mm High Speed Silent Wings 3 fans for intake. They performed OK, but my 3090ti was always idling hot (around 50C) when keeping the Silent Wings at low RPMs for silent operation. The Silent Wings were rather loud and annoying even at just 75% speed (around 1650rpm for that fan, to be fair).I replaced them with 3 of these P14s, and they are so much better. My GPU idle temps dropped by 10C while maintaining silent operation, and even at full speed, the noise from these fans is very tolerable.It's a bit unfair to compare a 120mm to a 140mm, as a bigger fan will move more air--full stop. There is a 140mm Silent Wings variant, and I'm sure it's great. It probably performs slightly better than the P14, but I didn't want to shell out nearly $90 for another set of premium fans.The P14 PWM PST gives you everything you need and nothing you don't. It pushes a lot of air at a reasonable noise level, and has a reliable fluid-dynamic bearing (the same type of bearing that Noctua fans costing nearly 3x the price do). In the box, you literally just get the fan itself and a little bag with 4 mounting screws. The fan itself is not particularly interesting or eye-catching. The plastic it's made of feels a bit cheap. But that's OK--it's a fan. You don't need anything else. You slap it in your case and forget about it. It's black, and won't distract from the aesthetics of your build.

After reading a review about these fans I got curious and decided to try them. Not at all disappointed.Beforehand, I was using Noctua P14 redux fans as intake for a Lancool 205M case. There is a restrictive front panel with a dust filter and a solid front panel with holes on the side, so I figured the Arctic P14's static pressure would excel here.The Noctua P14 Redux fans were already pretty good, but these absolutely blew them away. In a FoldingAtHome workload, CPU temperatures dropped by about 3°C and GPU temperatures by between 3-4°C - while being significantly quieter and less expensive, to boot. This doesn't sound like much, but it is a large performance boost from just switching out the fans. There's an occasional low pitched hum or whine at some frequencies, but I don't notice it much over headphones.However, installation was an absolute pain in the rear. I don't know if it's the screwdriver, the screw themselves, the case I was using, or an unfortunate combination of all the above, but screwing the fans in felt way more difficult than it should have. I ended up stripping a screw and having to replace it with a spare screw I had around. I definitely feel as though Arctic can improve in this area.Overall though, I'm happy with my purchase.**UPDATE 6/29/2023** Revising this to 5 stars. I told Arctic about the problem with the screws and, to my surprise, they sent me a pack or not 4 or 8 screws, which would have been enough - but 20! More than I needed, but better to have it and not need it.

Pretty quiet even on a fast speed, keeps my PC cooled well

Had some trouble getting the screws in, which require force to thread into the hole. It forced me to mount the fans on the inside of the cage so I could screw in from the outside. Also, one of the screws had a smaller top that kept going through he cage slot.Other than that, they seem much quieter than the fans that came with my Fractal North case - so i'm overall very pleased. I researched 140 fans without price consideration and these affordable fans seemed to be the best.
