Of course. The issue is the Real Time Clock. I have to edit Date in the Terminal occasionally.

Yes, but stacked..? :
Will the fans have enough intake space to draw air into the fan?
Any HVAC technician will tell you that you always leave a space at least as much as the fan diameter for it to intake/exhaust air from/to. At LEAST..!
Without that much space they tend to run (blades) stalled, which means they are then more noise makers than fans.
Electronics 'CAD kiddies' may be 'the worlds best' at designing PCBs for various computing components,
BUT!!!
They
are absolutely F-clueless! when it comes to very basic aero and basic thermal cooling! (rules of thumb)
As in; an ant in a burrow is more aware of a passing Jumbo 747 at 50 000 feet than they are of any cooling gumption whatsoever!
A good example is the new RPi5's stock cooler.
There they have a fan trying to blow through what!? opening between the fins vs the HS's other more open to airflow through the fins side.
That means that the RPi5's ...'Official' FAN is in fact 'running' in a stalled state.
ie: They have taken a fan and turned it into a noise maker rather than a fan.
Take a
look for yourself with your aero hat on... Not looking anywhere near optimal is it!?

Obviously the HS is designed for a fan from above...
I took one look and mentally tossed their official cooling solution on my now huge 'idiot's best try at cooling' virtual trash pile!
If you are an audio/music type, noise isn't on your list of 'yes-please!' is it!?
But hey: It's on already (least personal effort) and 'OH-so-Official!'
