I would respectfully leave that to you 
Very good point you have raised. I was about to create a Topic on efficiency as I have spent a lifetime eradicating inefficiency 
Part of the subject you have raised is the NOISE 
which as you know is wasted energy having to cool 
down those cpus, graphics card etc - another Topic 
my Dell with LXDE-MiniMaxOS is silent the fan has not come on yet 
It is so stupid having a rig like this to do ALL normal everyday tasks - I manage to use just 40% of my 3MiB RAM when multitasking on the old HP G60.
Hope you will help me with independent easy tests of LXDE-MiniMaxOS… 
Thanks again - Stay Safe 
ps who has marked this as a solution - not me…?
