After 6 days of back and forth with careful question formulation, I have the following straight from MSI. I thought it would be nice to have the facts as MSI sees them laid out here so that certain things that keep coming up need not be debated over and over again. Many of these things have been said by someone in one post or another but not with the authority of MSI behind the conversation. Some of these things have been contradicted in posts and we can now know for sure those contradictory statements are incorrect as far as MSI is concerned.
1) MSI calls the chipset the Northbridge, even though they admit the technicality that the thing we used to call a Northbridge is incorporated into the CPU architecture.
2) The 790FX/SB750 chipset is under the heatsink by the RAM slots, connected by a heat pipe to the MOSFET heat sink.
3) The chipset max operating temperature is 80C.
4) MSI will not talk about unsupported software like Speedfan and Everest. However, if you prod them with pointy sticks, they will talk about supported software that ships with the motherboard. AMD Overdrive TMPIN readings apply to the following devices:
TMPIN1 = CPU die temp.
TMPIN2 = Chipset temp.
TMPIN3 = System/Motherboard temp.
The following are my own observations that are not directly from MSI:
1) I have read reports that MSI has said that under 70C is a good idea for the chipset.
2) Everest's Northbridge temp runs 15C to 20C hotter than TMPIN2. I have contacted Everest and expect they will correct this problem as they have for me in the past with other motherboards. The AOD temp indicates that stock temp and most OC temps of the chipset will be fine in a well ventilated case without additional cooling, which was up for debate before the temp of the chipset was unequivocally reported.
3) Everest's CPU and core temp readings are the same as AMD OverDrive.
4) Speedfan's "Remote1" works in lockstep with Everest's "Northbridge" and that temp can be manipulated by a fan on the chipset heat sink - it is probably referencing the correct diode but interpreting the information wrong.
5) It's difficult to say what the other numbers in Speedfan mean, when related to the numbers that I can tell are accurate in Everest or that are provided by AOD.
6) Speedfan Speed03 is the CPU fan.
7) Everest GPU reading is the same as the temp report using nVidia software.
