Fan curve and system curve
WebApr 12, 2024 · Thus, the actual operating point for a fan must be determined by comparing the fan curve to the system curve (also called system resistance curve). The pressure drop that occurs when fluid flows through a heat sink, or any system, is a function of the flow velocity. If flow is completely laminar, the pressure drop is proportional to the square ... WebMar 21, 2024 · Thus, we recommend starting from 30% fan usage and increasing it once it crosses 30C (the idle GPU temperature a.k.a your room temperature). At or slightly before 80C is where you want to reach maximum fan speed so place a marker at 100% fan speed at a temperature nearing 80C. Press Ctrl + F to flatten the curve out beyond your …
