My CPU fan only turns at 1225 RPM and Speedfan has no effect. I want to speed it up. Here are my BIOS values look like:
*SMART control: Enabled (that's the only one that's not grayed out)
*SMART fan start PWM value: 28 (I'm sure PWM is pulse width modulation, which I've worked with in machinery)
*SMART fan start Offset (-): 30. (I know that's the adjustment from the temp sensor under the CPU, because the CPU has no internal sensor. So the offset is just a good guess at what the real temp is.)
*CPU Delta T: Plus 3 (I know what delta n is mathematically, but don't know what it refers to here)
*Fan1 slope PWM va1/1 unit: 5 (???got me. I'm sure PWM is pulse width modulation, which I've worked with in machinery)
Again, these are all grayed out. I can change nothing but the SMART on and off.
I could use some ideas.
