EK-Vardar EVO 120ER Fan @ TechPowerUp
 

EKWB takes their high static pressure optimized Vardar fans and improves upon them by adding a zero RPM mode to PWM-controlled fans. The dual ball bearings also get replaced to reduce bearing noise, and at $20, these aim to be the best-performing radiator fans for PC DIY watercooling around.
