Question Cpu is overheating with aftermarket fan

[Dinkle96]

I recently upgraded my gpu (RTx 2070) and my i7 7700k was running fine for the first week then all of a sudden I’m getting notification that some cores are approaching max temp. When checked it stated that cpu was around 100 degrees. I have an aftermarket fan and it was working just fine until recently. Now when gaming I get ten minutes out of it until I get the overheating notification. What could be the issue? I’m not overclocking and my case is sitting around 60-80 degrees when gaming. Do I need to change kind of cooler or something a bit more drastic?

the cpu fan still running?
full system spec? make and model of the psu?
redo the cooler, redo the thermal paste

And yes the cpu fan is still running. I’ll get some high quality thermal paste and see if that helps
