Corsair CO-9050005-WW Air Series SP120 Quiet Edition 120mm Low Noise High Pressure Fan Single Pack

These are quieter than the famous Noctua nf-f12s, which are amazingly quiet fans themselves! I didn't think that anything could get quieter. These most certainly and noticeably do. When compared side by side, you can hear an audible droning noise coming from the Noctuas at full load, for want of a better expression. The Corsair's do NOT produce this sound at max RPM, and they are rated for the same speeds, more or less.Now some independent youtube reviewers have pointed out that with the Noctuas mounted to a rad, they cool the CPU better than the Corsairs by a margin of 3-4'C max. I currently have an overclock on my i7 4790k at 4.7ghz on all cores at 1.2v adaptive. With the h100i GTX and the Corsairs, I hit a max temp of 81'C after an hour on Prime95v26.6 on the small fft test. Yes, that's quite high but when you consider 1. The all core high overclock without custom loops 2. the duration of the small FFT test during UK summer ambient temps and 3. the silent setup of my system...a 3-4'c improvement for some noise wasn't appealing to me. This is because 81'C is within the thermal limit that this CPU can handle, so long as it is not sustaining this high temp for long periods of time.In Battlefield 4 online multiplayer, my CPU temps stay in the mid 50's, skimming the high 40s on the low end and 61'C at the highest end. The noisiest part of my system is actually my GPU, 980TI that only wakes up during gaming. Other than it, I wish I could shut up that Corsair h100i pump that everybody knows about.I would not recommend any other fan other than these Corsairs, despite still using the Noctua NF-F12s, a Noctua AF 140mm fan and a pair of Noctua's IndustrialPPC 3000RPM fans. If you want silence, and second best cooling in this category of static pressure fans, get these Corsair quiet edition fans. They cost less too!

This is a great fan, solid, chunky feel to its operation, responsive, efficient, excellent cooling curve. There is not anything to dislike about this one to be honest. Does what it says on the tin as they say, and for what it is, an extremely reasonable price. These days, buying a PMW capable fan is a no brainer, because if you don't utilise PMW at present, you soon will once its installed - you'll wonder what you did before without that level of control.Its a Corsair, so you expect quality, and it is. Don't hesitate, go for it, its well worth the slightly extra cost. Penny-pinching on fans and cooling is counter productive. If you have a powerful machine, good quality fans - not manufacturer stock fans - are a must, and this fits the bill perfectly. There is a marked, significant improvement in cooling ability over stock fans.Nice One Corsair ...... :)

These fans are perfect for any enthusiast computer builder.A note for those considering purchasing:These fans are better suited for a placement against hard drive bays, radiators on water cooling loops, and CPU coolers. Please consider placement before making purchase as the AF120mm fans may be better suited for your desired use.I purchase these to replace the alternate models that come stock on the Corsair H100i AiO loop. Straight away I can tell a different in the volume levels and acoustics after installing these fans, and even at 100% speed through Corsair Link they are still noticeably quieter than the stock fans.The rings are a great part of the aesthetic and can easily be swapped out. A lot of enthusiast builders have been known to respray them to match the aesthetic of their rig.These fans are great for cooling efficiency, aesthetics, and nice and low on the dB meter. A definite recommendation from me to anyone looking to give their computer a nice new kick, and perfect if you like your case window with none of these fancy lighting setups.

Excellent replacement fans. If, like me, you chose a case over it's aesthetic appearance, rather than it's cooling , airflow, capabilities, but also have a power horking AMD graphics card, then these high static pressure fans are a must if you don't want to be renewing hardware every 6 months.To put things into perspective, I'm running an MSI AMD R9 390x gpu inside the NZXT Razr h440 case. During graphic intensive games like Fallout 4 and the Witcher 3, the GPU temperature would stick at 94c with no movement, despite the Twin Frozr's best efforts to cool things down. I suspected that the cause was the ambient hot air being pushed around inside the case, rather than being sucked out. So, I swapped out the rubbish exhaust and front fans supplied with this case with 3 of these bad boys at the front, and one Corsair AF140 at the back, exhaust position. The effect this had was instantly noticeable from the start- the amount of air these fans can push through the case is unbelievable. Now, my GPU running temps rarely go above 80c at maximum stress (typically stay around 75c in a cool, well ventilated room). The AMD R9 390x is a hot card, so this airflow upgrade was a must, and even gave me a bit of headroom for slight GPU overclocking.The only aspects of these fans that I don't like are the noise at full RPM and the stupid rubber mounting holes. You can't screw these in, unless you have bolts that can go straight through the holes, so don't bother using the screws supplied. The fans are quite low when being worked, but are generally quiet if at mind to low RPM. If your motherboard doesn't have 3/4 pin fan headers, invest in a fan controller because the sound will drive you mad if you're just web-browsing or doing a bit of work while these are spinning at max. There are silent versions, but I doubt their as effective as these for providing strong air flow. I would suggest configuring these fans to spool up dependent on GPU temperature using SpeedFan. Idle speeds will be suffice at cooling the rest of your system, providing you have a decent CPU cooler, you'll only really need maximum performance if your fans are obstructed by drive mounts or, like me, have a hot graphics card.All-in-all, excellent fans.
