I've never met a cutting tool that had a perfectly sharp corner. Even if not intended, I'll guarantee that there is some finite radius at the base of Cathar's fins (and that it is beneficial, albeit perhaps a minor affect).

The only way to really avoid one is to bond pre-cut fins to the base with solder, braze, whatever. Even then you'll still get a radius, however, simply due to the surface tension of whatever you use to bond.

I only brought it up because it looks like you've intentionally got a lot of white space over the die. Perhaps it's merely an optical illusion. Perhaps it's real and a requirement for having enough cross area for flow. I don't know for certain.

Also worth noting that the AMD die isn't centered over the four bolt holes. If you managed to survive the entirety of Cathar's thread at OCAU, you probably already know this.
