Dream Machine Special Edition CPU Fan Replacement 2026

Is there an updated guide and information on cpu fan replacement for UDMSE / UDMPRO ? My unit started acting up and from the sounds of it replacing the fan could be a good start.

Does Noctua make any?

Other options?

No hard drive currently installed but might do that primarily to get more fans moving. Already read there is a good replacement for the HDD FAN (https://www.amazon.com/dp/B071W93333?th=1) .
