So my electric pusher fan stopped pushing and I got a new fan assembly (Behr) to replace it.

I put the OBC to Ktemp almost everytime I drive, so I'm familiar with the average temp. With the OE fan, it was around 92 deg.

Now with the new fan, I am usually at 96 deg in the same conditions.

Coolant level is fine, nothing else done but the aux fan replacement.

Any ideas why this is?

FIXED!
Summary:
-Aux Fan died
-Aux fan replaced
-Temps on OBC were still slightly higher than when before aux fan died. No other symptoms and AC operating normally.
-Replaced engine fan clutch
-Temps now lower
