Noctua NF-A9x14 HS-PWM chromax.Black.swap, Premium Quiet Slim Fan, 4-Pin (92x14mm, Black)

I buy Nocuta fans because theyre efficient and quiet. These are even called Quiet fans, but they sound like a helicopter spinning up, Im so confused. I used the anti-vibration pads they come with and still it sounds like a plane taking off. I set the fan curve to 10% and I can still very much hear them. My computer was completely silent before. I dunno if these are just defective, but its two separate fans that I bought, would be a big coincidence if they were both defective.

so far my 2500k is staying cool with this fan OCed from 3.7 to 4.33ghz.. I can run at 4.4ghz with a stronger louder setup.. but I think I found the sweet spot in power consumption and heat at 4.33ghz with this fan!

Needed a replacement fan for my low profile L9A after noticing the original fan was damage due to my handling of it (sound of slight grinding). This was a perfect replacement fan and ran quiet that I remember.

Drove me nuts, I uninstalled it within an hour. I would rather let my CPU throttle than listen to this obnoxious fan. Its two times louder than the 6 other Noctua fans in my system combined. Contact me if you want a lightly used one of these for free, otherwise Im going to throw it in the trash.

Great build quality and reputable brand. Highly recommended. Quiet and efficient fan.

What is there to say. It’s quiet and powerful.

Good fan. I have no complaints about the fan itself. I was really irked about the big model number stamp on the fan but it came off with some alcohol and A LOT of rubbing.

Excellent replacement or addition to provide better cooling. Plug and play.

I was unable to find thin fans like this one from other vendors, but this still exceeds my expectations. Noctua seems to always make great products that are quiet and effective.

So much quieter than any other fan Ive used. Others are cheaper for a reason.
