I think this sounds a bit ridiculous but I worry about it so I thought I'd ask.
I'm a laptop musician and I use a year-old Macbook Pro running a smorgasbord of stuff in Ableton Live. I arbitrarily decided that my laptop felt hot enough, thank you, when the CPU meter was about %30. I have this totally made up and imaginary thing in my head where I believe that anything above that is fine for short bursts but that I wouldn't want to sustain a level much higher than that for the hour or two that I'm typically playing, lest my laptop get too hot.
So: should I really worry about this? Should I be monitoring my system some other way than Live's CPU meter? Tell me I'm being silly, because I'd really like to add some more stuff and work the ole' computer a bit harder.
It does get proper ventilation. It's on one of these
, which I feel is marginally better than tabletop, as it lets a bit of air underneath (the laptop sits on pads not really visible in that photo). I'd rather not use a USB laptop fan because I'm pretty much out of USB ports.
