Anyone ever try is fan guard mounted radiators?

This one from Amazon looks like it’s good for 20 CFM. The M15 from the pdf would be equivalent to the Amazon link.
More money than the Derale 15300 but would make a slick installation. I also like the configuration of the ports better and it would likely have better pressure drop characteristics.
