85 Celsius is way too much!
If you didn't change your voltages, then they should be at the default values. Check them with CPU-Z and then compare with the Intel data sheet for your CPU.
Try to check your cooler and thermal paste if they are setup correctly, and if they are OK, it's time to get a new cooling solution!
Also, try to be aware that some mainboards have defective sensors, so you can try to touch your CPU heatsink, and if you can touch it for more than 1second, then it doesn't goes up to 85 Celsius!
