If you are over heating then odds are the rad you have no is toast. Lots of people run stock rads with the AC fan as their “electric fan” and never have over heating issues… (unlses they beat the shit out of it on the track) but daily driving, it shouldnt be an issue.
Myself, I run an S14 rad (which is slightly bigger then the S13) with the AC fan and I’ve never ever once over heated.
