One was a conventional pull fan and i even tried a 16 inch pusher in front. I had a proper shroud for puller fan, billion therostat, the spal pwm fan controller. Tried it all on my auto tt back in the day. Every time i thought it worked the temps would start to creep up. Imo 212f is way too high. I was getting 200 or 205 with the oem setup. Not sure what the issue was but i never got the spal setup to work right.
Your post has motivsted me enough to try again but i don't think its gonna work for me.
