I have read reports of the 14" needing to rev up fans earlier and faster than the 16", but that was during benchmarks which may not indicate what happens during normal usage. I know the 14" would still be silent unless stressed, but what about heavy Logic use? Has anyone used it in long sessions in Logic with a large number of virtual instruments, like a typical orchestral template? Preferably stuff from East West and NI that still isn't native? Thanks.
