The Tcase value is used as a reference and, ideally, the processor temperature should not exceed Tcase while the processor is idle. The temperature may go higher than Tcase for some period of time if the processor is under stress.
The Intel® Core i3-4160 processor’s Tcase temperature is 66.4 °C.
Temperature issues are usually caused by improper fan/heatsink integration or its failure. You may want to remove the heatsink, inspect its pins just to make sure they are not broken or bent and integrate it again. When properly installed, the heatsink should not wiggle or shake if you attempt to move it; the pins should not come up if you try to pull them up.

We suggest paying attention to fan speed, reset BIOS settings back to default, and check for BIOS updates from the motherboard manufacturer’s website.
