I am running a dell optiplex gx280 with a Pentium 4 3.0Ghz. To upgrade it i bought the same CPU but with 3.2Ghz. I carefully installed it but when i swich the pc on immediately the fan started to overwork gaining rpm on rpm till i swiched off. I repeated the operation, checking the fitting of the heathsink on the CPU. Still the fan never stopped to accelerated. Has anyone else experienced the same with the same Dell? I never read about upgrade the fan for such a small increase in the CPU.Anyone can help please?

Are you sure its an exact match, P4s come with different bus speeds and memory speed requirements.

Can you give model numbers off chips?
