It's not the end of the world if the radiator fan comes on every now and then, but if the fan comes on and is unable to bring the temperature down, then you have a problem. Mine never comes on in stop and go traffic, so it's 70mph hill climbs that limit the size of my grille block.

Yours looks good, but will it be the right size grille block in the summer? Just keep an eye on the scangauge and you'll be fine.

Btw, radiator fans work well at 0mph, but they don't add much cooling when you're already going at highway speeds.
