🔧 GeeekPi 2pcs Raspberry Pi 4 Quiet Fan: Efficient Cooling for Raspberry Pi 4 Model B/C, 3B+/3B/2B | 40x40x10mm Brushless CPU Cooling Fan Cooler in Black Review

I bought this to replace the standard fan on my Raspberry Pi case. It doesn't cool as well as the stock fan (about 1-2 degrees Fahrenheit warmer), but it works well enough and shines nicely. My only complaint is that there's a high-pitched howl that's only really noticeable when the fan is on ) . Otherwise it's quiet in the room, but it's still in the background.As I get older and my hearing gets worse, I'm sure it won't be a problem.

Update 12/06/2020 - Came back and added a star. The more other brand fans working with the Raspberry Pi that I come across, the more I appreciate those fans. You are quiet. They cool well. You look great. They are supplied with the necessary clamps. They come with screws. If you get four packs, they also come in a nice clamshell box, which is great for organizing those little bits and pieces that like Rasbperry Pi enthusiasts clutter up your desktop. Even if you compare them to Noctua - sure…

The fans on my Icy Dock 6x2.5″ case with 5.25″ spare got loud and then one of them died. They had wiring that suited my needs (2 wires with separate connectors). They move enough air to make a difference. I didn't care about the LEDs since they're on the server, but they were the cheapest fans at the time of purchase. They beautify the inside of my server. I can't say much about the volume as other fans in other parts of the server rack are louder.

I bought this fan to fit in a Raspberry Pi 4 Octoprint server case. It is powered by a raspberry pi using the GPIO pins on my raspberry pi 4. Installation is easy, see attached picture the black one with one of the ground pins (6, 14, 20, 30 or 34). This fan cools the case well, but it's noisy, which is annoying when I'm working 24 hours a day.

I have used these fans solely to cool my Raspberry Pi 4 with great results. So far they've delivered very consistent cooling with consistent reliability, and while you can hear the fans a little in a perfectly quiet room, the noise is imperceptible when there's other ambient noise in the room (computer fans, air conditioning, etc.). Room. Combined with two heatsinks (or with a GeekPi Ice Tower) and suitable 3D printed cases, I was able to keep temperatures under 30°C consistently. The only…

I needed fans to cool my 2 Raspberry Pi 4s and these 2 kits were cheaper than either of the premium brand fans. Connected to a 5V pin I enjoy the performance but the noise was more than I expected, quite audible and annoying in a quiet room. Connecting to the 3.3V pin almost completely reduces the noise, but of course you lose some power. I decided to run one on 5V since it was outside the door and I couldn't hear it anyway. This Pi is lightly loaded and never exceeds 38c. The other one I have…
