IS my NB or SB overheating

Alright when I run my barton xp2500 at 200 fsb after a while i get really bad sound distortion. I'm pretty sure that its the southbridge as that is the bridge my audigy 2 is going through (same problem when tested with onboard sound). Also the distortion would only happen when the hdd was put under stress or I was typing alot (usb keyboard also uses the southbridge i think). Just wondering cause lots of ppl mod there NB and I was wondering if the SB was really the problem or is it the NB. Gonna put vantec iceburgs on both bridges when I got home, but just thought I'd make sure my mobo (8RDA+) wasn't bad. Oh and none of my hardware is the problem, thnks for the input.

yes, we cool all bridges

ok thnks, this shows how much of a noob i am, lol

I have an Iceberg on both my bridges. The 8RGA's nForce2 MCP southbridge gets hot.

Sound problems are most likley a SB problem.
