Myhre, you have to have to Fangui exe that DIDN'T come from the fangui site. There are several threads buried in here by now (maybe we should have gotten one of them made sticky?) where a couple guys were fixing the display et al.
I think the thread you want is Fangui wishlist. In there will be some links from the guys doing the adjustments to fangui. Read thru the whole thing to make sure you get the correct last version.
The file you'll get from the thread is just the main exe, not the whole program. So you need the program, then copy replace the original with that file. Then you'll get the right temps
To give you an idea, GPU and DIMMS should be fighting to the highest temps. CPU and other should be somewhat similar, at least that how mine is going right now. other is vram. If i recall, the original flipped the GPU and Dimm or GPU and other. but it was never right
