Easycargo Raspberry Pi Fan - 30x30x7mm, Quiet 3.3V/5V DC Brushless Cooling Fan for Pi 3 B+, 2, B+, RetroFlag NESPI Case

Leider selbst bei 3,3V etwas lauter als die Version die bei meinem Gehäuse dabei war aber noch im Rahmen. Bin gespannt wie lange er hält.

Iniziamo col dire che il prodotto ha un ottimo rapporto prezzo/qualità. I materiali sono di ottima fattura. Funziona alla grande CONSIGLIATISSIMO

One lasted a bit more than 2.5 years running continuously in my PiHole with no dust filter, after which it was functional but excessively noisy. They do make a slight buzzing noise from new but that is to be expected from a 20mm fan. Mine is next to my main PC and it can't be heard over the fans on that. Airflow can be felt and there is a temperature drop on my Pi, again you can't expect too much from a 20mm fan. For reference I paid £9 on a black friday deal in Nov 22.

Product was as detailed.

The fans work but that is about it. Running at 5V you can barely feel that they are on. I would not attempt overclocking the pi with these.
