NoctuaNF-P14s redux-1500 PWM, High Performance Cooling Fan, 4-Pin, 1500 RPM (140mm, Grey)

They work perfectly, and are dead silent in my Define R4 up to around 50% PWM duty cycle. Only real downside was they don't come with the corner pads by default, but I'm not hearing any vibrations, so it didn't REALLY matter.

They're pretty good. The color scheme is ok, I would prefer all black fans, but it means it's easy to tell they are Noctua Redux models.They can get somewhat loud, but a good fan profile can tame nearly any fan. I use 20% from 0-60C, then 50% at 80C, and 100% at 100C. On a graph this results in a smooth, gradual ramp up. I can hear my computer fans when the CPU is under higher load (70-85C), but at idle, it's near silent. However that is also relying on a few NF-P12 fans and the two Scythe fans on my Fuma 2 so it's not a perfect representation.I don't know exactly how many stars I want to give these. They're pretty good, but I have no point of reference yet aside from the Arctic P14's, which is a different tier of fan. I'll eventually check out Thermalright 140mm fans to compare, which will probably be a lot cheaper and perform nearly the same. The P14 round is also an interesting design that I want to check out.Since these are still the best 140mm fans I own, they get 5 stars.

Bought this as a gift. He loves it. Makes a difference in computer performance. Cools well,good power, speed, and size. Cable was long enough.

I needed a set of 3x 140mm case fans for the top of my Asus GT302 case.I chose Noctua NF-P14's because they are some of the quietest fans on the market and they cool exceptionally well.Installed, they're much quieter than the 4x ARGB case fans that came already installed.I am very very happy with this purchase.

Super quiet even when PC is stressed. Have had no issues with bearings squeaking or rattling while gaming.

These are solid radiator fans for coolers that fit them (120mm mounting holes for a 140mm fan). I figured I'd give them a shot, swapping out a pair of Deepcool TF140s fans. In truth, the TF140s are overall better, the Noctuas have a hum at lower levels and while the overall db might be a bit lower on load, they also sound less pleasant, there's clear vibration here, since Noctua didn't deign to even bother having vibration pads, and honestly they don't sit as secure either. The cooling performance is exactly the same.Are these worth more than the old Cougar Vortex (can't get these anymore, best fans I ever used) or the current Arctic P12/P14 PWM series? Absolutely not. The Arctics are the current go-to fans, especially at and below this price point. The Arctics are actually all purpose, radiator and case, whereas these are really designed for radiator (although you can use them for case fans too). There are top end Noctuas for twice or more the price (which follow the new trend of all purpose fans), maybe those would be worth a look if you're interested---but you'd of course pay a hefty premium.These do look good, they perform solidly overall, cable length is good (and sleeved). It's not a bad buy, it's just, there's a better product out there so there's no real reason to use these. If I knew what I know now, would I have gotten these fans and taken the time and effort to swap them out? Nope, not at all. Fortunately at least this isn't breaking the bank, unlike the flagship Noctuas.

i absolutely love these fans!

I bought 2 of these fans to replace the exhaust 200mm I had for my case. The 200mm had started to slow and become an issue.Replacement was extremely easy and straight forward, at least for me, since they are plugged directly into the power-supply so the fan controller is bypassed and also on full speed.The moment I plugged them in these things started to put out some major air, and also made my PC cooler. I have ordered another 140mm and 2 of the 120mm (same brand) just to replace all of my fans.honestly great price for great fan, specially since the ones that came with my case are hitting 10 years olddefinately get them to replace stock fans
