I'm running kirbans setup with the Casper electronics wiring harness
Which came with the fan package
I highly recommend it been using it for 2years with no problems I'm running around 165 on a 70 degree day and about 187 on a 90 degree day with stock radiator 249 stroker
I’m running a set I got off Jegs that is 10 times better then the GN1 fans. I’m trying to remember the cfm they pull but I know it was a lot more then the gn1 fans and they where cheaper then those fans as well. I’ll look and see if I can get the part number and a picture.
