I tweaked the fan curve on my case fan because it runs at 100% when I am gaming. So I made it run at a max of 80%, which is MUCH more quieter, and it doesn't seem to have any impact on the max temperatures of my components under load. I tested 20 mins under 100% load before/after, reducing the fan speed by 20% had zero impact on any temperature readings. This may possibly be due to the fact that I recently upgraded my PSU, which has 120mm fan so it also helps to exhaust air out of the case.
But the problem is, unlike MSI Afterburner (which I used to control the fan speed of my GPU), I can't seem to find an option to make Speedfan auto run at startup.
If this is not possible with Speedfan, are there any other similar programs that can control the speed of my case fan and run automatically when the PC starts up?
