It it's a standard 120mm you're looking for, the Noctua NF-F12 is the best one. This is of course if you only care about quality and performance. For aesthetics, the Noctua is probably (and sadly) the worst fan you can get.
But if your computer is old, your case is a cheap one, you don't give a shit about aesthetics, or if your case for some reason is painted in the ugliest brown color, then go for it 😛
