| Summary | 0000656: Speed change stops | ||||
| Description | Almost always when I turn on my computer and auto-start Speedfan, the speed of my second fan (CHA) goes down only to around 90% and then stops, although it is configured to go as low as 50%. The first fan (CPU) comes down to 50%, however. When I manually correct the speed, to say, 40%, it is corrected to the minimum value and stays there as long as the temp does not rise. It is controlled correctly afterwards. It just seems like Speedfan "forgets" this fan speed shortly after startup. I think the temperature readouts (five of them) are O.K. Maybe this has to do with the Smartguardian feature, which I disable with Speedfan? Or with the configuration of my temps and speeds. I have: HD0 temp -> CHA fan Chipset temp -> CPU + CHA fan MB temp -> CPU + CHA fan CPU temp -> CPU + CHA fan Core temp -> CPU + CHA fan | ||||

Also happens to me with speedfan 4.31 Happens only when HD0 is controlled (HD1 was not tested)! Speedfansens.cfg uploaded. For more questions about my configuration, feel free to ask me. EDIT: This occurs only after system bootup. In this phase, the hdd is constantly heating up. I read in another issue about the algorithm that it only decreases the temperature when all trends are down. The problem is pretty clear now. One workaround for hdd cooling might be an option for setting a PWM to a specific value at startup. |

99% it is due to the temperature being controlled by the HD too. That temperature is read, for several reasons, once per minute. SpeedFan waits for all temperatures to go lower. But now I can read that you already discovered the reason. In your specific case, your solution might work, but I'm looking for a more general one. |

But the algorithm should ignore everything that is _below_ the desired temperature? That is, when I say that 45 degrees is desired and Speedfan should warn at 50 degrees, the fact that the temperature reaches 42 degrees shortly after bootup and then stays at (i.e.: does not drop lower than) 42 degrees should not bother the algorithm at all, IMHO. Could that be the general solution you are looking for? |
