These behavior's are typical and normal for a HCH1.

I use a ScanTool OBDLink MX with my Nexus 5X.

In my 2004, normal operating temperature cruising down the highway is ~184F. Longer grades will typically see a rise up to about 190F. One interesting feature I noticed on the most recent trip I took, is that the car will not enter lean burn until the engine drops below a certain reported temperature somewhere around 187-188F.

One of the radiator fans running after the engine has been shut off, is normal.
