all the electric fans I've seen stock or after market are right on the rad. I would totally agree if my issue was only around town or slow speed. But after 20 or 30 MPH a fan is useless. the very reason manufacturers went to electric fans. The mechanical drain mileage and HP at speed for nothing. My 62 impala SS 350 had a mickey mouse electric setup and never overheated just sitting in traffic. it seems more like a flow issue than anything.
