Both of my laptops have sufficient RAM for what they do
(Win11 Home=16GB, Win11 Pro=32GB) home machine for "home stuff", pro 
machine for "work stuff"

Neither has to do much paging, perhaps peak at 100 faults/sec during 
loading large apps, then calms down to single digits or zero afterwards

It always annoys me that as the amount of memory used (by total 
committed) increases, so does the chance/speed the fans are spinning, if 
the fan use was proportional to paging I'd kind of understand.

Memory chips don't know if part of them is allocated to a process or 
not, right?  Other than maybe some garbage collection, nothing goes 
around flipping bits for fun, right?

So how does being allocated, even when sitting idle, influence cooling 
required?

Anyway, I've always been a bit suspicious of the MemoryCompression 
service, so I'm experimenting with it turned off for a bit.
(powershell disable-mmagent -mc)

And it's the first time in years I have firefox and thunderbird both 
running with no fans in use ... not conclusive yet, but interesting ...
