I will try to find part number, with my 4 core I had to switch to mechanical fan untill I do some reworking of mounting points. Turned out to be a bit shy on room between rad and my March serpentine setup. I tried to run it as a pusher on front side of rad but it ran to hot. Ran a flexalite mechanical fan without shroud and had zero heating issues, but doesn't have the nice look of the electric fan.
