My system uses a Win 7 O/S, MSI -P67-G43 Mainboard (MB), a HIS Radion HD 6870 (GPU), i5-2500k, 750W p/s, 3 case cooling fans and 3 matched 19" monitors. Build in Jan 2012 w/no manual OC. Used mainly for Sim Gaming. System appears to run great. I just recently happened to check my temps while gaming w/OpenHardwareMonitor and the 2nd of 3 temp readings on the MB was at 106C. I have no idea what area Sys Temp '2' is monitoring. When I shut down the Game it immediately dropped to 60C. I reset all connectors and even relocated GPU card to different socket but same effect. Only seems to happen when I open/run a Game. Repeatable. Have not made any changes to system recently. Fans do NOT race. All other readings appear normal. CPU V low at .944, hi at 1.224; GPU V low at .950 hi at 1.175. Any constructive suggestions?
