Haitronic 30x30x10mm DC 5V 3010 Quiet(24/32dB) Brushless CPU Cooling Fan (2pin) Heat Dissipation for Raspberry pi 3, Raspberry Pi 2 Model B/B+ B Plus, 3D Printer extruder, DIY Arduino prototyping

Bought this 2 pack and have only used one so far. It is doing a fine job of cooling an Orange Pi One. Origionally the fan produced a slight noise but I quickly learned that once I balanced the air flow ( in my case having sufficient sized intake holes in my Orange Pi case to match the output) any noise I had disappeared! Time will tell the whole story but for now I am pleased with my purchase!

Works perfectly.Not sure why others are complaining that it didn't push much air. A 5v 30mm fan won't produce a huge amount of airflow. Maybe if it were 12v.Blows enough air to keep my raspberry pi cooled in my nespi case+, which has a heatsink connected with actual cpu thermal paste. Keeps the thing below 70 with a decent overclock on the cpu and gpu.

These fans exceeded my expectations they are great. I purchased these for my Raspberry Pi 3 running RetroPie with tons of emulators and games on it. Before these fans I was only running 2 heat sinks on the Pi and my temps were around 140 degrees Fahrenheit. After adding these fans my temps vary from 90 to 102 at the most. You can hear these fans when they are running but they are no louder than expected.Installation was a breeze, the plug goes right on the pins with no modification needed. I have two Raspberry Pi 3 setups both in cases. I mounted one so the fan is inside (blowing air out) of the case and one with the fan on the outside (blowing air in). The case with the fan on the outside blowing air in is on average 2 to 3 degrees cooler. I used a hole saw to make the hole for the airflow and a drill bit for the mounting screws.I have been using these fans for a little over 2 weeks now and I will update in a couple months if anything changes. I was NOT compensated in any way shape or form for this review, it is just a quality product from a quality seller.

I replaced the 30x30x7mm fans that come with/in various Raspberry Pi cases with these. They are very quiet and reasonably priced. I run one of my Pis 24-7 processing weather data and serving music and so far so good. They have already outlasted the original noisy fans. If you are replacing an existing fan pay attention to the room you need, i.e. heat sinks. The 3mm in additional height may require some modifications to the case.

Needed this to install into an NES style raspberry pi 3 case, and it fit perfectly and vented air out of the vents. I used some superglue and that's it. Overclocked the raspberry pi 3 and this keeps it cool.

HORRIBLY noisy. Very very loud high pitched whine when connected to the 5.5V GPIO pin or the fan connectors of the Nespi Case. While it does cool the Pi its just not worth the noise. The sound of my movie or game can't even drown it out.

Little air moved so the fan starts to spin even faster, drawing too much power from the Pi's GPIO port. This ends up underclocking the unit. Not to mention the unbearable bee-like sound this makes. Not recommended.

Great price, easy to install in nespie case. Has it’s own connection, really great. Loud, but that’s because it’s awesome
