What fans at the bottom of the NCase M1?

[kielo]

Hi,
I just got my NCase M1 but was wondering what fans I should install under the GPU.
Noctua NF-F12 PWM
Noctua NF-A12x15 PWM
Noctua NF-A12x25 PWM

With a 2-slots GPU, is it possible to mount NF-A12x25 fans? or must I need slimmer ones ?

Thanks

A12x25 will fit with a 2-slot GPU but there's a chance you'll get turbulence because the fans will be so close to the GPU's own fans. A12x15 provides a bit more breathing room and can bring the temp down of your GPU with a few degrees. You could combine it with a mild undervolt of your GPU to achieve a nice temperature.

I highly recommend to watch Optimum Tech's Youtube channel, he covers all of the above with his own Ncase M1.
