Questions about Noctua NF-A20 PWM

Will the Noctua NF-A20 PWM fit in a NZXT 630 (2016) case? I would like to replace the NZXT fan. Apparently the distance of the screw holes to the fan frame is not standard unlike the other manufacturers. https://forums.tomshardware.com/threads/why-do-i-not-seem-to-be-able-to-fit-200mm-fans-into-my-case.3593076/

Noctua NF-A20 PWM, item number 6399986, 5V or 12V? https://www.digitec.ch/de/s1/product/noctua-nf-a20-pwm-200-mm-1-x-pc-luefter-6399986 Here on the website the following is stated: Input voltage 5 V According to the manufacturer's no. NF-A20 PWM, this should be the 12 volt model. The 5 volt model has the manufacturer's no. NF-A20 5V PWM. Is Digitec giving incorrect information - is this the 12 V model or the 5 V model? @digitec: If so, please correct it on the website.
