G5 noisy!

Hi,all
I got something with my G5 PowerMac ,that seem make me uncomfortable
I don't know what happen with My machine,may be friend have info pls...

theres like 8 fans in a g5 its a wind windtunnel in there

Open up the side and clean it out, then see if it stays that way.

Are U running intense graphic or video work?

If so it tends to speed up the fans.

even i don't run any programs ,its still noise
and may be it's about casing,that casing is broken and I want to change it
but Till now I am still struggling to get it,it's like seek a diamont in my head ,in my country and out side ,very very seldom include my area,and the important I don,t have any account in e-bay and any credit card,,,,

it's really really make me have headache and stomachache................

thanks

and thanks for advice bro...

Even simple things like launching Safari would make my G5 sound like it was about to take off. Powerful systems, but you pay for it in noise.
