Review: The Silent Spinner of Dreams - Right, so I bought this Noctua fan because the missus kept complaining that my old PC fan sounded like a small lawnmower revving in the corner of the living room. Apparently, it was drowning out her telly programs. 'Get a quieter one,' she says, 'or the fan's not the only thing that's getting replaced!' Enter the Noctua NF-A6x25 PWM. It’s marketed as a 'premium quiet fan,' and I thought, 'Well, it can't be any louder than her complaining!' And I'll tell you what – this thing is a revelation. It’s so quiet, I keep checking it’s actually spinning. Honestly, you could have it on during an ASMR video and still hear every whispered 'crinkle crinkle.' It’s a doddle to install, too. Even with my sausage fingers, I had it up and running in minutes. Comes with all the bits – screws, extensions, even little rubbery doodahs to stop vibration (though my PC now vibrates less than my phone). Performance? Top-notch. Keeps the PC cooler than a penguin in a fridge, and not a peep out of it. Looks? Well, let’s be honest, it’s brown and beige – not exactly winning any beauty contests. But then, I don’t buy a fan for its looks, do I? If I wanted style over substance, I’d be shopping for designer curtains, not computer parts. In conclusion, if you want a fan so quiet it makes your old one sound like a jet engine and keeps your PC running smoother than a freshly buttered crumpet, this is the one. Just don’t tell the missus how much it cost, or you’ll be hearing noise of a different kind! 10/10 – would recommend, even if it’s beige.
Review: Just what I was looking for! - Needed this for a SFF build that I'm trying to keep cool and quiet and it works flawlessly in every regard! Good air flow and can't even hear it. I had to check it was spinning to see if it was even turned on it's that quiet. It's in a Stone computer case from 2012/2013 and it fits perfectly. I'd say if you got 6cm mounting system and about 2.5cm space for the fan it and a four pin header should be compatible! And considering how well it works I think its good value. I have brought other fans that claim to be silent and were anything but so yeah nice fan!

### ⭐⭐⭐⭐⭐ Quality but ...
*by L***P on 22 July 2016*

Bought as a direct replacement for the CPU fan of an old - 5 to 7 years - HP Compaq 8000 Elite ( small form factor desktop Mini-PC). Unfortunately although slightly quieter than the original fan I aborted the change. Reason being that with this fan in place I realised the noise I was hearing is actually more a consequence of the air flow required for a 65watt processor within the case. Simply put the air flow through the front grill and then the CPU heat exchanger was most of what I am hearing, the fans themselves produce little noise on idle. Which is a shame as I have a 17watts (Intel Cel-1037U) pico-PC that is completely silent and was hoping for the same - the old Intel Duo-Core E8500 is approximately 25% more powerful and as a casual desktop is very good even today). The Noctua Fan came with three cables (including a low noise 7volt adaptor) and rubber anti-vibration plugs plus screws, i.e. everything you ever likely to need. Clearly a quality product with a justified price tag, not sure however if such quality is actually ever needed nor the best spend on ultra cheap old PCs. I'll re-use the fan on something more appropriate - aux case fan the most liekly.
