Okay, here is a goofy question! How do you know if your CPU is overheating? Is there smoke? Does a message popup and tell you? Right now, I can put my hand over the fan and the air blowing out is a little warmer than the air and all I have up is IE. It is about 75 in my house (95+ outside). I have rendered animations that have taken about 36 hours to complete, keeping an eye on the CPU's performance via the task manager. Poser keeps it pushed to about 80% during a huge render. So then again, how would I know if the CPU is getting too hot? jaebea
