k3mp said :- "Using TPFC 6.2:
255: Fan is Off
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.

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&
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..
1st: install TVicPortInstall41.exe
2nd: run hpfc.exe
ask me for sources.
Keep it simple does:
If ctemp < 45 Then
If speed < 128 Then
write_ec(&H80, &H2F) //write 128 (fan slow)
ElseIf speed < 255 Then
write_ec(&HFF, &H2F) //fan off
ElseIf ctemp < 52 Then
write_ec(&H80, &H2F) //fan slow
If speed > 82 Then
write_ec(&H10, &H2F) //fan fast

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.
