My problem is that my CPU temps will rise a lot to around 100c even with nothing open randomly. This does not happen all the time it will happen 1 day and not happen for weeks, but then happen again and it's done this for a while now and I don't know how to fix it anymore. I have tried reapplying thermal paste, factory resetting to see if it was malware of some kind and I don't know if it's a CPU problem or my cooler. Thanks if you can help!

CPU: Intel - Core i7-7700K 4.5GHz
