Noctua NF-A14 ULN, NF-A14 FLX and NF-A15 PWM Fan Reviews
Ryan Martin / 11 years ago
The NF-A15 PWM was designed with one main reason in mind, to give 120/140mm CPU coolers more performance by cramming a 150mm fan onto a 120mm fan mount. If your 120/140mm CPU cooler allows for a bit of extra width then you should have no problem fitting these on to it, however I’d recommend looking at some measurements and the fan mounting mechanism first to see if it will fit.
The first internal page contains all the usual Noctua feature set which you can get more specifics on here.
You can see straight away that Noctua have included fewer accessories since this fan is designed for PWM operation not fixed speed operation like the NF-A14 ULN and FLX fans. A low noise adapter is included to limit the speed but the Molex 4 pin to 3 pin adapter has been scrapped in favour of a Y-splitter cable and a PWM 4 pin extension cable which is much more appropriate for a PWM fan.
The back lists off some specifications and the key ones to note are speeds of 300-1200RPM (default) and 300-900RPM (low noise adapter).
