Well, since I can't really afford to buy a new DC 2.0 G5 to replace my pretty much brand new DP 2.0 one, I am gonna try the CHUD fix and see how it affects my temperatures. Hopefully the the difference in temperatures isn't big and I won't have to ebay the G5 (the sounds aren't that major, they just annoy me like a dead pixel would).
I'll let you guys know how it goes, whenever I get the G5 back that is. I bought the computer 3 weeks ago, and used it for 3 days before bringing it into the apple store over this problem. While telling me that it wasn't a problem and that it was universal they scratched the case, so now that's getting replaced. So I should have it back later this week to test it.
