SpeedFan knows this - it uses the same interface as my program to control the fans - and it probably just sends commands for "speed level 0" for pwm values 0-33, "speed level 1" for pwm values 34-67, and "speed level 2" for pwm values 68+ (or something like that, specific thresholds might be different). The Dell BIOS interface only allows for three speeds. "DellFanCmd ec-disable" will not allow SpeedFan to have more granular control. I can't tell the BIOS to control some fans automatically but not other fans.) (Additionally, this is an all-or-nothing switch. "DellFanCmd ec-disable" just tells the BIOS to stop trying to control the fans. In all of the laptops that have been tried, if you try to control the fans using SpeedFan only, it works for only a moment and then the BIOS immediately sets the fan speed back to what it used to be. If you are able to control the fans from SpeedFan without running "DellFanCmd ec-disable", then this system definitely behaves differently than a laptop. Thanks for the communications and being willing to work with me on this so far. When you say that with "DellFanCmd ec-disable" the fans will be unlocked for manual control, does that mean that Speedfan will be able to work at values other than 70 or 0? I apologize if the question seems obvious as I'm still getting the hang of everything. If the program was able to give me the option of how many fans I want to control, I feel that it would work to make sure RPMs don't drop down so low. I have a feeling that your DellFanCmd program can help so that the RPMs don't drop below a certain value, but since I can only control two fans out of the "five" that my system has the values on the front case fans end up dropping to like 500 RPMs which is way too low to keep the temps down. The only downside to using speed fan is once the value drops below 70, the RPMs drop WAAAY lower than the "idle" that I have them set at through the BIOS. The value to make them go from "idle" to "holy cow it's working!" is 70. I had actually done that with the speedfan software and am able to read the RPMs for all of the fans in my system (four active and one at 0 since there's no fan connected to the HDD fan pin).
