The fan blade rotation speed on the electric fans can be a problem-----If the fan is not powered it will rotate at a rpm that effectively is sorta like an airplane propeller on a engine out situation---and it basicly takes up the drag coefiecant of a complete circle---so it really becomes an solid disc? BLOCKING the flow of air---
If your fan is in front of the rad, this is happening all the time----
Looking at the pic of your radiator the amount of airflow thru that is really limited by the amount of visable fin that you can see between the blades----------Last edited by jerry clayton; 07-22-2022 at 06:55 AM.
By popular opinions-just a grumpy old man key board bully--But really, if you are going to ask for help on an internet site, at least answer questions about what you are asking about-----
