Recommendation for a quiet fan?

Wed Aug 28, 2019 3:18 am

I put together a media server with the Raspberry PI 4 and it came with a canakit case with a fan. Unfortunately the fan is just loud enough it's distracting when I'm watching a movie. Can someone recommend a good replacement fan/case that's quieter? Thanks!

If you check Noctua's site, I believe the 40x20 is quieter. However, I have a couple of systems using the 40x10 Noctua, and it is very quiet (I can only hear it when I'm very close, in a very quiet room).
My mind is like a browser. 27 tabs are open, 9 aren't responding,
lots of pop-ups...and where is that annoying music coming from?

just got the 40x10 5v from noctua... got 3 units actually....

setting it up now....but initial test confirms what HawaiianPi mentioned....

made my own mounting plate for the fan using 3mm thick acrylic plate

I just received this one and it is so quiet you can only hear it if you hold the case right up to your ear:

I built a file and media server using Openmediavault and a Pi 3. It's easily fast enough and doesn't need a fan!

One of my 4s has the fan that came with this case. More or less silent running on 3.3V.

Not needing to get at the 5v pins would really help for me. I'm setting up several Pis that need RTCs...and those sit on both 5v pins.

Thanks to everyone that replied! I checked out the dimensions on the Noctua 40mm fan and it's to large for the case I currently have... Could I ask for recommendations where to find a Raspberry PI 4 case it would fit in?

Once again... Thanks to everyone for their help!!!

No fan needed - get a flirc case

All I do when I find a noisy fan is reduce its speed.

Either add a resistor inline or run it via PWM at around 30% duty cycle

I know this is not what you are asking but Flirc case really works. I had 7 dockers running and the temp was still at 57C. It's just unbelievable but truly works.
