Pr 4100 fan upgrade secifications,

I have been getting familiar with my PR 4100 since I replaced my old MyCloud 4 TB NAS. I have done enough research to find out about replacing the RAM to upgrade to 16 GB. I have seen a Youtube Video in regards to a Fan upgrade. I would appreciate if you could advice me on a Fan upgrade in line with the 16 GB RAM upgrade. I have noticed 5V Fans available and 12V Fans. I would like to knoe if the 12V Fan I have researched would be a good idea. The Fan I have in mind is a Noctua NF-A12x25 PWM, Premium Quiet Fan, 4-Pin (120mm, Black). I was reading one of the posts on the PR 4100 Fan and this one is available in 5V and 12V. Please advise me to what I should do.

Thank you
Harminder Singh
