NoctuaNF-F12 PWM, Premium Quiet Fan, 4-Pin (120mm, Brown)

I bought two of these to replace the stock fans on a Antec Kuhler H2O 920, cooling an i7 3770K, not currently overclocked (breaking in the Arctic Silver 5), but I have confidence that this cooling solution will more than handle it.The fans are more than I could have hoped for; quieter than the (very quiet) Kuhler pump at low speeds, running down to about 120 RPM, and still pretty quiet at full tilt, achieving a steady average 1500 RPM with less than the stated 10% variation. The comparison to the stock fans supplied with the Kuhler is stark, in addition to being far quieter, the sound at top speed is subjectively 'more pleasant'; a background hum rather than an aircraft throttling up for take-off!The accessories supplied with this fan are second-to-none. The short cables fitted to the fan worked perfectly with the connectors from the Kuhler, allowing tidy cable management, but the neatly sheathed extensions came in handy for tidying the cabling for the other case fans away behind the motherboard tray. The Y-connector would be very useful if you had fewer PWM headers on your motherboard than case fan mounting options, and the LNA (Low Noise Adapter) if your motherboard did not allow you to limit the top speed. The mounting options are similarly well thought out, with vibration damping mounting cones to complement the (removeable) silicone corner mounts on the fan itself, as well as conventional fan screws.If I had to find anything at all wrong with these fans the only thing I could mention would be that the silicone corner mounts made it slightly tricky to get the mounting bolts for the radiator engaged, as they add a little extra width. Once the first bolt was located and tightened a turn or so the others went in fine though, and the compression in the mounts allowed them to be tightened securely. This really is a clutch-at-straws to nit-pick however!In summary, these are excellent fans, which do the job asked of them to a very high standard, all whilst remaining extremely quiet, and leaving you with a nice little handful of spares to use elsewhere in your PC build. Well worth every penny!

Noctua NF-F12PWM Case Fan 120 mmI just love it when you get a product that has attention to detail - the packaging is old Rolls Royce quality - loads of connectors just in case you want to link fans together. When you open the box quality exudes - I love the colours of the fan and many don't - but unlike many I doubt that I will see them again until I have a problem with my PC and have to open the case up again. My intention is to use this new build and not look at how sexy it looks inside.One irritation was installing them - the fan has eight soft rubber corners fitted to it - be aware that the buggers can fall off when trying to pull the very clever soft rubber connectors through (no screws) to fit the fan. I noticed that one had fallen off and wasn't sure where it was or if the fan actually had it when I took it out of the packaging (never expected that they could fall off) finally found it and the very soft rubber was a pain to try and put into the fan (long stalks that needed to be fed through holes and soft rubber stalks that didn't want to go through the holes. A bit of hide glue could have made these corner buffers stay in place because you would never ever need to remove them.That being said they serve a great purpose - the soft rubber corners buffer any potential vibration of the fan being transmitted to the case - not that these fans have any vibration as the fan is virtually silent and vibration free.If you read this you might think that there is more text on the negatives - well my final conclusion is that Noctua are excellence par excellence - total quality and I am about to order a couple more for my new case and build.Brilliant product!

This fan is BEAUTIFUL, I have it as my CPU fan as the fan that came with my cooler moved very little air on my personal computer and I use one as the only case fan in the home/office computer (as there is not much room near the intake of the computer)This is Noctua's pressure optimized fan designed with radiators and CPU coolers in mind but you can use it in a similar scenario that I have with the office computer. It comes with screws, anti vibration gromits, 5 volt and 7 volt adapter and a 4 pin fan extension wire as the wire coming off the fan is quite short.This is one of my favorite fans out there, it is robust, silent in normal use, shifts a nice bit of air and has a 7 year warranty. the colour scheme leave a bit to be desired however I've grown to like it, before it annoyed me but now it feels prestigious. Despite what some people have said online you should not remove the fan blades and you cannot paint the fan as it will ruin the motor in the fan and it will not preform as good nor for as long. Unlike some other fan you cannot peal off the sticker to add oil to the fan (not that you need to I just never saw that commented anywhere else)If you choose this fan for environments where a high static pressure is required, you will not choose wrong with this fan.

If you're on the fence - buy these now.Bought these to replace the plastic crap that came with my Thermalight Peerless Assassin. Taking these out of the packaging - you feel the quality. They have everything you need in terms of cables. You will need to keep those metal clips if you're installing these as CPU fans. These things are SILENT even while gaming. My PC is finally as quiet as I always wanted it to be.I always just used fans supplied by the case, CPU etc. I want to replace my case fans with these and my case fans are not an issue.The only noise from my PC now is my 4070 and a 4TB HDD I have yet to replace.
