Easycargo 30mm Fan 5V 3.3V DC Quiet Fan for Raspberry Pi 5 4 3B+ 3007 (4-Sets)

Great set of fans, but I do not have a raspberry pi... I have a Sony XDR-F1HD HD tuner. These have a known problem with overheating and not starting up the next time they're turned on. A fix is to install a fan blowing on the internal electronics. This little fan is an ideal fit - I "glued" it inside with double sticky tape and connected it to the 3.3V power supply inside the unit. This fan is very quiet and inaudible with the cover back on the tuner, and it starts up reliably now. I know this is a bit of a corner case use, but if you need a little fan that doesn't need much voltage and is super quiet, check these out! Oh, and if you're actually doing the same Sony mod I did, the service manual is available - just google it!

Seem to work well, quiet. Accidently put 16v on it to start, and it didn't burn up, so that's something. Tested two. Both reliably start up with as little as 2.2V. Almost completely silent at 5V, though being so small of a fan, you need a wet finger to even feel them running at that speed. At 6v, you can just hear it if you're a few inches from it, and at 8v it is humming pretty good. I think as another reviewer wrote, not sure how they came up with the 120ma amp draw at 5v; I didn't see anywhere near that. Closer to 27-30ma. Even at 12v and howling, it is only drawing around 55ma. I'll probably configure these to come on in a resistive load box at some preset voltage or just switched. Can't speak to longevity, but so far I'm happy.

Just finished installing in my Pi case (iUniker Raspberry Pi Fan ABS Case). Perfect replacement of the original (now noisy) fan and runs so quiet I had to take the cover off again to make sure it was running.

I have an older Raspberry Pi 3 that runs a little hot. When I purchased this Pi, it came with a fan but the thing was noisy so I trashed it. This fan is very quiet and was able to cool my Pi by about 10 degrees, which is just fine for what I'm doing. I really didn't need 4 of these, but the price for all 4 was acceptable.

These are some nice fans. They are so quiet I had to put my hand over it to feel the air. The airflow is very nice for a small fan. I'm 100% satisfied. I can't hear my pi4 anymore that sits about three feet from me at my desk and it stays nice and cool. This beats the pants off the stock fan that came with my kit.

I marked them down on noise level because they do make noise if they're in contact with anything since there's not enough clearance between the fan blades and the edges. This is a basic design flaw that could be prevented by putting a slight frame between the fan and casing that wouldn't prevent air flow. I put one on my pi3b and the Temps went from 160 degrees F to 90-96 degrees F so they're very effective. That pi was overheating before and now it's reasonable.

These were nice and quiet from the start, but starting at about 1.5 years one started making noise, then it got quite loud around 2 years and now the other in use is making noise so need to replace both (and still have 2 spares from the 4 pack), but was expecting a longer life out of these.

Needed a replacement for a Raspberry Pi case fan these work great.
