Review on 2-Pack Dorhea 3007 Quiet Brushless Fans For Raspberry Pi 4 And Other Models - 30X30X7Mm Cooling Fans With 3.3V And 5V DC For Robot Projects And DIY Projects by Jason Staggs

Revainrating 5 out of 5

Very quiet! Flow rate is what you would expect.

These fans are extremely quiet. The flow rate is what you would expect from a 5v, 30mm fan. I used one as a supplement to the heat sinks on my Raspberry Pi 4. I had to build a custom mount, but it was worth the effort for a silent cooling solution.

  • Used in electronic project and worked perfectly.
  • The packaging for these fans may be excessive and wasteful
