My Intel supplied fans have been very quiet.
If you got some third party fan, I'd believe it, but do call the supplier and ask for an exchange.

I Built a new computer with a stock Intel 3 Ghz CPU and Fan. The Fan is unbelieveable loud. Is this a common problem with the Intel Fans? Should I just buy a less loud aftermarket fan? Any thoughts on why it's so loud? Thanks for any help.
