Thats a nice addiction. The thing is that my case has a tube like that (but it does not have the space for the fan) the problem that i have is that the HSF does not react as it shoul so to keep the temperature down and that makes my CPU go up to 70 degrees and then my computer stops. And thats annoying. Allthough i've puit the value in BIos for automated shutdwn at 75 celsius. but my CPU didn't ever reach that temp but it still shut off.
