So here is my story.
I play Flight Sim X. It is a very CPU intensive game. It has never bothered my computer to play it. Recently I upgraded to windows 7. Ever since then, when flying custom aircraft on FSX my computer would shut down. Now my BIOS is set to sound an alarm at 85C, and auto shut down at 90C. On hot days when playing games the alarm has sounded many times, so I know it works. However these crashes were occurring with no warning.
After downloading programs to keep an eye on my temps, and updating drivers, I ended up changing the alarm to 90C and disabling the shut down. For the first time, I can now see the culprit. Using PC Wizard 2012 I can see all my core temperatures are sitting nicely at around 80C, however there is one named CPUTIN which jumps up to 92C when I'm playing FSX (Even though the core temperatures remain around 80C). This explains why the alarm wasn't sounding; the CPUTIN temp sits around 60C, but once I begin playing, it spikes straight up to above the shut-down temp. Now that I've disabled the shut down, the alarm keeps sounding intermittently when ever this CPUTIN goes over 90C, even though the CPU is still over 10C lower.
What is CPUTIN?
Why is my BIOS paying any attention to it when the rest of the temperatures read far lower?
Are there any known fixes for this?
This is driving me insane. Help is much appreciated.
