I'm currently on a G5 DP 2.3 with 4.5Gb RAM and having this issue:
Garageband 08 and Logic Express 7.1 send the fans crazy - even when playing back one single track - I have performance set to reduced in power settings and CPU load during this is between 50 - 60% ie negligible.
By contrast Propellerheads Reason 4 can run 10 tracks of software instruments without the fans even murmuring.
As a comparative test, I played 4 480p h.264 movies at the same time to push the CPUs and even with CPU load at 160% the fans were still quiet.
Is it possible that CPU load can discriminate between the type of work being done? I'd have thought not?
Or is it bad coding? Again, hard to believe on flagship products?
I haven't come across this before - I was previously using a G5 iMac 1.8 and a G5 Quad - they'd both fire up the fans during any heavy task, whether it was audio, graphics or video.
Has anyone experienced similar or got any thoughts?
I haven't had any kernel panics or crashes yet but I'd rather prevent rather than cure.
