I don't think i have ever heard my fans switch to full playing games (even farcry for a few hours)
Using Fangui 2.2.0
...and setting the fans to high certainly is loud :P (Tapek must breath heavily if he can't hear it over his own breathing
) But yeah, like I said, I have never heard the laptop fans get to that sort of level by simply using it. (So Tapek's comment is quite right)
I can't compare the noise to anything, because I have nothing to compare it against, but idle, it doesn't make a sound... only time the fans are going to be getting loud is when the machine is @ load playing a game or something, and then, you'll be too distracted by the game to notice the sound won't you?
I don't think the sound of the fans are an issue at all personally.
