Nice setup! I like that 64GB of sweet trident royal
I also sported the same ancient NH-D14 for more than 10 years across multiples builds. Noctua are just the best IMO
Finally, I am currently looking for a new case and the Torrent is among the short list. I've heard that the Phanteks P500a might be a better choice for me though as I am rocking the Galahad 360 and the Torrent is apparently best when coupled with an air cooler.
Anyway, mixing manufacturers does not matter. As long as you're running the exact same speed and timings on every stick, you're good to go. Of course, those timings have been carefully picked after hours of stability tests!
