Although Intel's Thermal Specification for "Throttle" temperature is 100°C for your i3 4150, it is, of course, not advisable to allow a processor to approach Core temperatures that high.
Here's the operating range for Core temperature:
Core temperatures above 85°C are not recommended.
Core temperatures below 80°C are ideal.
Core temperatures increase and decrease with Ambient temperature.
Your Core temperatures are OK, however, "gaming" is typically a light to moderate CPU workload. A decent aftermarket cooler would give you more thermal headroom to accommodate higher seasonal ambient...
