Cooling slim fan Mod issue

[8soupapes]

Checked they are rotating in the correct direction?

 
I was sure, but checked this morning to be 101% sure



There are those ones with the "embossing" option (no spam) http://fmic.eu/wentylatory/458-plaski-we...or-16.html

Maybe bought the wrong ones?

oem fans are more like 150w each and have a nice cowling to duct the air in.


however when driving along the coolant should not rise above thermostat temperature

120W says servicebox   https://i.imgur.com/C8ZCiIF.png

The "sudden" peak of 105º was going up by mountain road behind a slow car. Nothing heavy.

Today I checked it and once reached 97-100º and fan starts working is not capable to cool down to 90º parked and at idle.
