Are these temperatures expected?

Hello,

I have a Asus H87-PRO motherboard with Intel i5-4440 @3.1GHz CPU. The CPU cooler I have is the Cooler Master Hyper 212 EVO. While stress testing the cpu using 'stress -cpu 8', i get a cpu temperature of 84C. The ambient temperature is 30C.

No overclocking done.

Are these temperatures expected and how can i reduce them?

Those temps are very high for that cpu. I'd wager the heatsink may not be fully seated. I ran a stock heatsink for awhile and always blamed my high temps on it being stock, but after replacing it I noticed only a small portion of the metal actually touched the thermal paste and it never actually seated. I was getting close to those temps and higher.

First thing I'd do is reattach the heatsink and apply new thermal paste. You don't need fancy thermal paste whatever the heatsink came with if any is left over.

That cpu is designed for a maximum safe temperature of 72C and I'm surprised it hasn't tripped the thermal kill switch yet. It won't kill the CPU just turn it off during high temperatures to save it from being damaged.

Your system temperature (looks like a motherboard sensor) is very high. What kind of airflow do you have around and inside of your case?
 
Get a different temp monitor just to make sure those are correct. Definitely open the case and get some direct airflow into the case via fan or something to see if it makes a difference, which it probably will. Come back and let us know, because it looks like you have some type of air blockage or poor air circulation happening.
 
Thanks for comments I suspect that SYSTIN temperature is a bug. This is being a remote server, i wont have physical access for some time. Until then i will throttle the cpu usage so that all the cores are not used together at 100%. With a single cpu at 100%, i am getting lower temperatures.
