Hello sirs,


I am putting together an ITX system and the 120MM radiator will not fit with two 120x120x25 fans. I purchased two NF-A12x15 PWM and am waiting for their arrival as those WILL fit in the case with the radiator. However I am having second thoughts and am curious if one NF-A12x25 PWM would actually push more air through the radiator then the two slim fans in a push/pull configuration.


Are you able to tell me which configuration will force more air through the radiator or if there is a better fan configuration Noctua offers to maximize air flow?


Thank You!

Greetings from Noctua!


Thank you very much for contacting us.


We recommend two NF-A12x15 PWM fans. These two fans have a higher cooling capacity than one NF-A12x25 PWM fan.


Kind regards,
