Easycargo Raspberry Pi 4 Heatsink Fan Kit for Cooling Raspberry Pi 5 4 3, 30mm Fan Heatsink for Electronics Robotics Development Boards DIY 3007 30x30x7mm 5V 3.3V Quite Mini Fan Small (Black 1 Pack)

Works pretty well. The difference is noticeable. I am using it with an orange pi 4 pro and a 3d printed case. Pretty good deal for all of the items at once, instead of buying them separately. They make a little bit of noise, it sounds like a mosquito.

These heatsinks and fans reduced CPU temp by 20 degrees F on my RPI3. RPI is running Home Assistant and was running about 120F but dropped to about 100F after adding the heatsing and fan.

I use my raspberry pi in a greenhouse, so keeping it from overheating was important. The heat sinks and the fan reduced the temperature of the CPU by about 10C, which is pretty amazing. The only reason i gave 4 stars was because the fan started making noise after a month.

I was a little worried because other kits say the thermal tape were not conductive but these worked great. My android TV box was running 50-70 degrees based on use. After applying the heatsink on the cpu and ram and adding one fan blowing on the cpu it now is at 30-50. I hoped for a few degree improvement but this exceeded expectations. Love it!

I used this to cool my custom laser-cut + 3D-printed Raspberry Pi case. It keeps this very cool, and it doesn't seem noisy. The heat sinks stick well. With a pack of four, I can make more cases!

I use them in Raspberry Pi cases. Perfect size and appears to do the job. Here's some test results on an RPi 3B+ mounted in a 3D printed enclosure. Used "vcgencmd measure_temp" to read the CPU core temperature. Does a nice job. Room Temp 26.0°C Open Case, no fan 52.1°C Closed case, no fan 53.1°C Closed Case, with fan 40.8°C

I downloaded two images from orangepi website. Ubuntu server and debian. One of the 5 boards I bought actually booted to ubuntu-server. I was able to get in through ssh. The rest of the boards didnt boot and locked up with solid lights on ethernet port and no red light flashing on front while booting. Once dialed in to ubuntu-server "apt-get update: would not finish and resulted in a number of python centric errors coming from a file in /usr/lib. It looks like orangepi devs chained this file to apt-get update function. But on release they didnt include the needed python packages to support. I went to install pi-hole and that scrip errored saying we cant refresh packages. I was able to run apt-get upgrade curiously but it did not clean up any errors that dealy with upgrade. So one out of 5 of these boards booted up to the point of plugging in a fan to the fan header. The fan was a 5v fan but since doing this the board will no longer boot. I wasnt able to get debian image to boot either, on any of the boards. I think I killed the one working board by plugging in a fan. The schematic on the orangepi site shows a fan header..... Based on what I see with both error filled software images that werew not built correctly and hardware that does not work I would avoid this project.

I set up a Pi3 as a media streamer and it began overheating after about 20 min of streaming 1080 video. I got this fan, cut out a hole in the pi case, and mounted on the inside of the case. I oriented it to pull hot air out of the case, and drilled some holes on the side of the case so cool air would be pulled over the board. Since installing, the pi has not overheated once. It barely feels warm.

Ottimo prodotto. Ventola silenziosa. I dissipatori aderiscono perfettamente sui chip. Consigliatissimo. Fare solo attenzione ai cavi della ventola perché non sono completamente flessibili.

Conforme à la description a voir la fiabilité avec le temps

Did not receive the heat sinks. Only received the fan. Very disappointed.

Le compagnon ideal de mon raspery. Mon raspberry chauffait en visionant un film en full hd. Maintenant tout va bien et en silence. Le ventilo est silencieux et suffisament fin pour entrer dans la boite. Il fait un peut bricoler pour l installer mais ca va. J ai fait des trous en plus dans le boitier pour la circulation de l air.

Ventilateur très silencieux en 3V. À voir dans le temps mais première utilisation très satisfaisante.
