I'm having a really strange issue after installing Tiger. When I run apps that use 3d graphics (ie Wow or the RSS screen saver) i hear this high pitched rhythmic noise. I opened up the case to try and pin point it and it seems its coming from around the CPU area (I have a dual 2.5 G5). I thought it may be a fan on the graphics card but the 9600xt doesn't have one. I dusted the fans and case just in case but it didn't help.
Is anyone else hearing this noise? It almost sounds like a small fan that is spinning a bit roughly. Are there any secondary fans inside the CPU area?
Update: I found a thread on the apple discussions with similar symptoms
