Noctua NH-D15 fan replacement?

[fordongreeman]

If I wanted to replace the fans on the hulking Noctua NH-D15 CPU cooler, what diameter fans do I need to get?

I'm looking for compatible fans with LED lights, particularly RGB, what would you recommend?

Do they come in any color besides beige?

Yes the new Chromax https://www.amazon.com/gp/product/B07654B9MR/ref=ox_sc_sfl_title_2?ie=UTF8&psc=1&smid=A1Z5H6ZGWCMTNX

and these are nice https://www.amazon.com/gp/product/B076569Y8X/ref=ox_sc_sfl_title_3?ie=UTF8&psc=1&smid=A1Z5H6ZGWCMTNX

Will this cooler physically interfere with my RAM dimms?

Is this roughly comparable to the NH-D15?

Yes the R1 Ultimate may interfere with the RAM. The R1 Universal shouldn't. It has a thin front fan. https://www.newegg.com/Product/Product.aspx?Item=9SIA4UF5VU1002

It is comparable to the NH-D15. Why do you want to switch? What are your system specs?

Does the R1 Ultimate have better performance than the R1 Universal?
