Review on 🔋 upHere 120mm 3-Pin High Airflow Long Life Case Fan for PC Cases, CPU Coolers, and Radiators - 3-Pack SR12-BW3-3-US by Joel Wright

I don't use them for standard purposes so they run off a 12v case fan hub which determines the speed they spin. but even at full speed they don't change loudly. I'll try to see how long they can last, during that time I'll run them at a constant speed for various long periods of time to get the air moving. I like the fact that they are really cheap. but that also means they will probably break quicker than I can imagine.
