I don't really know why, or really what the names of these even mean but TMPIN3, AUXTIN, and TMPIN4 are noticeably high. And to be honest I've never even seen them on there before today. Should I be worried?
Those are the motherboard's built in sensors. Programs like Speedfan often show incorrect readings for these sensors. I use HWiNFO64 (or HWiNFO32 for 32 bit systems) to monitor temps and CPU, GPU, & memory usage. I prefer it for several reasons, one of which is that it gives you the option to disable those sensors (citing high system resource use), and it reads all your possible sensors and usage stats dead accurate. You should go by the sensors embedded in your CPU for temp monitoring when overclocking, as they are the most accurate (and read the highest). Give HWiNFO64 a try, it's free, and better than all the others I've tried.
