I recently bought a Dell Dimension 4600 Desktop with a P4 HT 3GHz and one thing drives me crazy: a horrible high-pitched noise coming from the CPU fan. It doesn't depend on the CPU load, even when my system is nearly idle the sound level is unbearable. It get's a bit worse when I start a graphics demanding application (read: games).
I checked if the CPU fan is damaged, but it isn't. Other Dell customers have the same problem. I compared my system to those from different vendors and it's disproportionally louder. I already searched the web (e.g. replacing the built-in CPU fan) but couldn't find a solution.
Did anyone solve this problem or has "good" suggestions ? I don't wanna get through the hassle of Dell's support or return the computer because I need it every day.
PS: My ears have an average sensitivity, so loud means loud :)
