But with open fins you could use a saw blade mill like these:

I have some in different sizes with a sideway mount to make such grooves.
Yes I know that with the blade but on my mill that can cause me some trouble... And I need a blad with minimum 80-100 in diameter.... Not that cheap.
I try it that way if it does take to long I will do it with a blade.
At the end it doesn't differ that much if you mill slots like on your heat or open fins like my one.
The only sucking thing is the time because I can't go deeper than 1-1,5mm per cut
