On behalf of Tom's Moderator Team, welcome aboard!
Although Throttle temperature (Tj Max) for your i7 4790K is 100C, Core temperatures above 85°C are not recommended.
Here's the nominal operating range for Core temperature:
Core temperatures below 80°C are ideal.
Core temperatures increase and decrease with Ambient temperature.
Idle temperatures below 25°C are generally due to Ambient temperatures below 22°C.
Highest Core temperatures occur during stress tests or heavy rendering and transcoding, but are lower during less processor intensive applications. Gaming generally averages around 55°C, yet can range from 40 to 70°C, depending on how a particular game title allocates CPU / GPU workloads, as well as differences in overall cooling performance and ambient temperature.
Once again, welcome aboard!
