Overheating 360 new engine

Here’s the deal my friend. I get that it’s not complicated. The only thing I haven’t tried is going back old school fan as suggested by you. I get it but I have these things in stock. Also just because it works on your set up doesn’t mean it will work on mine. I appreciate your help honestly do but at the end of the day your at home thinking about it and I’m at home doing it.
I'm a lazy back reader. Did you say you've verified the temp with an IR temp gun? I mean.....I guess what I'm askin is are you SURE it's really gettin that hot? Like 100% sure and not 99%.
