High CPU usage and High Fan Speed

Hello,

About a month ago I bought a MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports) with 16 GB Ram and i7 3.5 CPU so I don't have problems with CPU usage and RAM usage.

But i am having a lot of trouble with it, fans are high speed even its not to much things running, CPU get above 100% just importing a lot of photos to iPhoto, or downloading files from DropBox when I was setting up it.

I am a developer and when launching the simulator I have also this CPU problem...

Already did SMC and nothing happened. There is any way I can test if my CPU is ok?

What should i do?

Is this normal?
