Did you install it yourself? You might want to double check that all the four pins are firmly in place, although all the temps are close to each other indicting it's probably in place correctly.
Since Real Temp uses P95 to test sensor movement, it will be higher than you would normally see in everyday usage. Plus you probably still have Turbo/HT enabled which will push the temps up even higher.
If your ambient temperature is high where you are, that also has an impact on temps.
Replacing the stock cooling is a good idea, especially if you plan to overclock.
As it is, it's within the 'safe' range although it is very close to being thermally throttled.
