The BIOS for my new motherboard has an advance feature where you can set fan speed thresholds, so the fan will go faster if the CPU is hot and slower when it's not. This is neat, and I basically understand it, but something is completely perplexing me and I can't find any guide which explains it. That is: what happens off the ends of the curve?
If I set the first point as
Here's the UI in question.. first, what a curve looks like after you've created it:
and here while configuring it (you can see the temps on the X axis):
Which I hope illustrate my puzzlement. I've found various guides and howtos, and none of them even mention this.
If I set the first point at, for example, 33°C and 48%, what happens when the temperature is below 33° C??
If the answer is "that's the behavior up until 33°C", what happens at the other end of the line? If that's set to 90% and 90°C, is that the top speed ever, or does it go to full speed after that?
