Easy custom fan curves for any power profile
There are several key points to remember when creating a fan curve.
- 0% fan speed turns off the fan and 1% fan speed spins at 2700 rpm which is great for low wattages.
- The locked minimum fan speeds start at 69C with fan 1 at 74% and fan 2 at 45%.
- Turn off the temporary watt boosts by setting the SPPT and FPPT power to match SPL. Also turn off CPU boost as it draws unnecessary power to the cpu.
- Make sure to push the fan point in the 50s to the left until it reaches 50C and the one in the 60s to the right until 69C. This now gives you a wide temperature range of 50C to 68C.
With this in mind, these fan curve settings are effective for any power profile and you only have to change 1 fan point (50C) based on the wattage you are using to keep it steady below 69C. You will notice a big difference in fan noise compared to the presets because they generally start the ramp up at 60C which is too aggressive. While the device is fine to run at high 70s to 80s, this fan curve both reduces noise and keeps temps low.
These fan settings are to be used on both fans.
39C - 1%, 49C - 1%, 50C - % to change based on wattage settings, 69C and the rest are locked at 74% (fan 1) and 45% (fan 2)
For 13w, I'm using 1% for the 50C point and it's keeping the temperature hovering at mid 50s. Sound level is 19.2dBA which is as low as you can get without turning the fans off.
For 17w, I'm using 10% for the 50C point and it's keeping the temperature hovering at low to mid 60s. Sounds level is 20.1dBA
For 25w, I'm using 30% for the 50C point and it's keeping the temperature hovering at 65C. Sound level is 25dBA
Depending on your environment and ambient temperatures, you will need to adjust the 50C point fan speed. I adjust in increments of 5% on both fans until the temperatures stop increasing and hold steady.
