noisy ATHLON fans?

[yoshald]

I've built a couple systems with retail (meaning a fan comes attached already) Athlons and the systems make a kind of subtle howling noise. I think it's the CPU fans. I've observed this on a 550 and a 750. Any comments?

Yes............ Noisy

The Athlon retail fan does seem noisy then usual. Time for a Golden Orb?

That Golden Orb looks keen. http://www.coolerguys.com/CPUCOOL/athlon.htm
I wonder if it's a lot of trouble to take off the AMD heatsink. It looks like it's glued on. Or would it be better to simply replace the fan?
