I can't unassociate linus tech tips from noctua in my head and so can't bring myself to buy them given that channel's incredible bias and how much they shilled for them.
Can't speak for the 7950 but my 7900 idles near 60c and peaks at 85c on a 240mm aio. It's hotter than I'd like, but my understanding is that the X3D models run quite hot regardless of how much cooling you give them.
