|0001872||SpeedFan||Fan control||public||2011-09-18 21:13||2011-09-25 19:18|
|Priority||normal||Severity||minor||Reproducibility||have not tried|
|Status||resolved||Resolution||no change required|
|Platform||P6T-SE||OS||Win 7 x 64||OS Version||Win 7 x 64 pro|
|Product Version||4.45 beta|
|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.
|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.|
|Tags||No tags attached.|
|Motherboard Model||Asus P6T-SE|
|Video Card Model||saphire HD5870|
||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.
