I've got both the 25mm Redux and the original 14mm slim fan, the 25 mm is quieter because it can spin at a lower RPM to achieve the same cooling at the thinner 14mm, but if you need to fit the fans in a small space, get the 14mm, I have 2x of the CPU version of the 14mm, which IIRC go upto 2500PRM vs the usual 2200 RPM, but they only come bundled with the NHL9i cooler, or you can try do ask Noctua to order them seperately and directly from them via email (like I did) I told them what I was doing and sent them pictures of others who had done it to their 1080 mini's, they loved the idea and let me purchase 2 fans, and they sent me a free fan cable extensions, and a Noctua fan header splitter to join both of them into 1 header. Very nice company! but your mileage may vary depending on who responds to your support email to them.
I have a ncase m1 so i think i should go for the 14mm ones.
