| Summary | 0001872: No CPU Fan Control on Asus P6T-se if using a 3 pin fan in the 4 pin connector | ||||
| Description | Quote from issue 0001530 as the problem is the same (difference is the motherboard) : "I thought that if I added my MB to the heading I might get a response, that is why I have posted this again. Has anyone been able to get Speedfan to control a 3 pin CPU fan connected to the P6T Deluxe v2 CPU_Fan 4 pin connector? Speedfan will not change the speed, but I think it maybe because my CPU fan is 3 pin and the connector is four pin. Speedfan will change the speed on the 3 pin chassis fans connected to the P6T Deluxe v3 Cha_Fan1, Cha_Fan2 and Cha_Fan3 connectors, but these connectors are three pin." This is the same issue as the one reported on P6T Deluxe v2 mb. http://www.bugtrack.almico.com/view.php?id=1530 | ||||
| Steps To Reproduce | No control period, always reproducable | ||||
| Additional Information | My cpu fan is a 3 pin fan. Cpu mb fan emplacement is 4 pin. | ||||

I think that the solution will be to use the correct type of fan: 4 pin one. |

I think the issue would be the same with a pwm fan. Anyway, i ll let you know next time i open that case (maybe in 1 week or 2 cuz i got alot of work the next 14 day), i ll give it a try with a 4 pin then report status here. |

Remember to enter CONFIGURE / ADVANCED and set PWM MODE to MANUAL, SOFTWARE CONTROLLED or something like that, because the BIOS might have set that option to a value that doesn't allow fan speed changing. |

Back to the report ;). So i tested using a pwm fan. That will allow speedfan to vary the speed of that fan. What you said "I think that the solution will be to use the correct type of fan: 4 pin one" is correct. Otherwise, on the advanced chip panel, there is an option named pwm "x" type. It can takes 2 vallues : PWM output / DC Output Setting it on DC Output should allow a 3 pin cpu fan to be controled via speedfan if i understand correctly. But infact, while setting to DC Output, the fan will just go fullspeed and the program wont allow to change his speed. Is it a bug ? |

Unfortunately, those options need specific hardware support. Changing the bits in the hardware monitor chip is only the first step. The availability of the correct external circuitry makes the rest. I think that Intel boards have a circuitry that makes both types of fans work. This is not the case of Asus boards. |

Thanks for the explanations. I think we can set that issue as fixed then. |
