Betreff: Lenovo G575 loud fan

[musayms32]

  It does not reduce the heat. This reduces the rotation speed and the fan noise. The resistor reduces the operating current of the fan.

  This scheme works fine on my Lenovo G575 Model: 20081, CPU: AMD-300E 1.3GHz, RAM:4096M, Win XP.

this looks like a dirty workaround  if it spin in lower speed then heat will appear sooner , I feel this should be controlled by software , i do this using ACPI call on linux ...

btw have you seen those paper foil hacks too ?

Ok, I agree with you, but I have not found another way to make the fan quieter under Win XP.

In Speedfan 4.45 temperature CPU (AMD E-300 1.3GHz):
idle   46-49C;
load  55-62C.

can you tell at what temp the fan turn on . and then off ?
