Where is the mainboard temp sensor on the M4A89GTD, I didn't see it mentioned in the manual.

I hope its on the MOSFET and/or NB heatsinks that are connected by a pipe.

Without the cheap/kind of loud front bottom 90mm fan* on, the mainboard temp is about 25-26C, thats with my OC, and temp stays about the same, gaming or not.

*(that I modded in place on the inside of the metal case, and put a mangledy cut tin can between the metal case and front plastic cover, and some duct tape)

With it on, the temp drops to 15-16C, which must be about the temp of the air down at the cool floor level by my bed, the wall thermostat for electric heat is set to 19C= ~68F

The idle CPU socket temp (no core temps on unlocked x3 740) in this study went from 31C @1530 RPM to 27C @1320 RPM.

It would be nice to think the MOSFET/NB temps effectively drop 10C degrees with the fan on, but is that really the case?
