Well, people do sometimes speak of "hot" pages (or spots) ... and there  
are no good verbs associated with "activation count". Oh, and you might  
say "the situation heats up" in case of increasing memory pressure.

And remember that in physics, temperature (at least in the cases where  
it's used by non-physicists) does measure something approximately like  
average particle velocity, which some (non-physicist) people might well  
call "activity".
