The Dynatron A45 is a low-profile heatsink designed for AMD Ryzen processors on Socket AM4 or AM5. It features a copper heatsink with a vapor chamber base, a 4-pin (PWM) connection, and a 12V voltage. The fan speed varies depending on the duty cycle, with 2000 RPM at 20% duty cycle, 4900 RPM at 50% duty cycle, and 8700 RPM at 100% duty cycle. The performance of the A45 is measured in CFM (cubic feet per minute) and dBA (decibels), with 5.59 CFM at 20% duty cycle, 14.76 CFM at 50% duty cycle, and 26.25 CFM at 100% duty cycle. The noise levels are 23.3 dBA at 20% duty cycle, 43.5 dBA at 50% duty cycle, and 62.2 dBA at 100% duty cycle.
