I'm working on a part cooling fan and wanted to know which fans I'm looking for. I ordered these:2pack 50mm x 15mm 5015 12V Dual Ball Bearing DC Brushless Cooling Blower Fan BB5015H12 with 2 Pin Terminal UL TUV [
www.amazon.com]
And they work great but don't respond to pwm at all,, they're binary at 100% or completely off. This leads me to believe that lowering the voltage, 2 pin pwm doesn't work, which makes me wonder, which fans do I need to get 50% airflow at 50%?
