k3mp said :-  "Using TPFC 6.2:

 

Manual Levels:

255: Fan is Off

254-128: unknow

128: Fan is "silent"

80: Fan at medium speed

54: Fan is loud

1: maximum speed"

 

I found that on my 4330S that 128 and 254 on Manual both have the same effect as choosing the Bios setting.  Namely that the fan runs at minimum level all the time but is not silent.

Hey Capvermell1,

when disabling the BIOS option "Fan always on while on AC power" the fan will stop on level 255. Any other level between 128 and 254 will be the same speed (my thoughts, not proved!).

 

Level 255 will have no effect when the bios option is enabled and you are on AC power.

 

I'm actually testing with ACFanControl.

Here's something to read about embedded chipsets: http://www.p35-forum.de/index.php?page=Attachment&attachmentID=3056

 

Setting the Byte 47 with ACFanControl to 128 will be "silent", 255 will be off. Maybe anyone is able to configure this program?

simple written HP Fan Control in Visual Basic..

 

http://dl.dropbox.com/u/4537271/HPFC.zip

 

1st: install TVicPortInstall41.exe

2nd: run hpfc.exe

 

ask me for sources.

 

Keep it simple does:

<snip>

If ctemp < 45 Then
If speed < 128 Then
write_ec(&H80, &H2F) //write 128 (fan slow)
Sleep(10000)
ElseIf speed < 255 Then
write_ec(&HFF, &H2F) //fan off
Sleep(10000)
End If
ElseIf ctemp < 52 Then
write_ec(&H80, &H2F) //fan slow
Else
If speed > 82 Then
write_ec(&H10, &H2F) //fan fast
End If
End If

</snip>

This is cool, but were you able to completely turn the fan off?  For me, pushing Fan OFF switches FAN level to 82 or sometimes 74.    Also, the temperature reading seems off -- it keeps showing 31-32, where my other monitoring software reports 45-50.

 

Thanks.
