Review on 🌬️ Wathai 12cm High Airflow 2Pin 12V Dual Ball Industrial Cooling Fan - 120mm x 120mm x 38mm by Mark Loredo

They're not for silence! However, they do exactly what they are supposed to do. Move the air! And, my God, her! I have a Ryzen Threadripper 3900 series and they tend to get pretty hot. I mean hotter on average. However, after the installation. Dude, that helped! My computer ran between 63 degrees Celsius (145 degrees Fahrenheit) and 33 degrees Celsius (91 degrees Fahrenheit) on average. This increased cooling efficiency by 40% while running these types at just 1500 rpm. they accelerate to 5300 rpm. Yes, they're loud when they go over 1500 rpm, but they help me sleep as they sound like a regular fan for that quiet ambient noise.
