|0000439||SpeedFan||Fan control||public||2005-12-31 22:00||2011-03-19 17:48|
|Platform||Shuttle DB61G2||OS||XP||OS Version||SP3|
|Summary||0000439: Fans no longer controlled|
|Description||Speedfan always worked correctly, with no problems until recently when it stopped working.|
Can see all values (fan speeds, temps etc.) and config looks like it always did.
The auto speed control box is checked -- speed valies stay at 100%, don't change at all. Changing the values has no effect on the fan speed(s).
Everything works except the speed control.
Downloaded latest version - no difference.
(Wonder if this is related to XP updates???)
Verified that bios can adjust fan speed - works ok.
|Steps To Reproduce||Start Speedfan.|
|Tags||No tags attached.|
|Video Card Model|
I had a similar problem after I reinstalled WinXP -- worked before, but not after. Turned out that the motherboard driver that was used in the reinstall was using a version that didn't fully support the smbus (maybe). I do know for sure that once I installed the newest motherboard chipset driver, fan control returned to normal. Same with the IDE driver -- the older version didn't support SMART, but the newest IDE driver allowed Speedfan to read the SMART info.
FYI - my motherboard uses the nForce2 chipset and the drivers I ended using were from nVidia's site.
Hope this helps!
