Review on 🌀 upHere 120mm PWM 4-Pin High Airflow Case Fan for PC Cases, CPU Coolers, and Radiators 3-Pack, Long Life SR12-BW4-3-US by Micheal Wright

I don't use them for standard purposes so they run off a 12v chassis 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.
