I have waited for three hours for it to turn off before, now I just turn it off after a few minutes. This has been happening for about a month now. I don’t know about the temp sensors, at ideal they are, CPU:23, system:42, GPU:57, all in degrees centigrade (I have a Thermaltake Ultra 120 with a Thermaltake Smart Blue 120mm LED). The motherboard is a Gigabyte GA-N680SLI-DQ6.
