Hi all, I just wanted to share an interesting issue I just discovered running Garritan on my laptop. This issue is certainly not specific to Garritan and is not a problem or defect with their products. It just happens to be what I am running on this particular laptop when this issue arises.
First off, I have a fairly powerful laptop - 3 Ghz dual core Pentum IV processor, 2 GB RAM and a 120GB hard drive. It can really generate some heat! (more about the heat in a second)
I am running multiple instances of GPO, Jabb, Strad and my sequencer on my laptop and most of the time things work great! But occasionally everything starts to stutter and the CPU usage goes way up. I basically cannot continue.
I have been doing some testing and I noticed that this usually happens after the cooling fans have entered "turbo" mode (they are running at the highest speed). So I finally realized that the machine is getting very hot and so the CPU is throttling itself to 50% speed to help reduce the heat. This explained the sudden jump from 50% utilization to near 100%!
Most laptop CPUs have a feature (I think it is called speedstep) that allows them to slow themselves down to conserve power when they are not being fully utilized. I did not realize that they would also do this to avoid over heating.
So I was wondering if anyone knows of an external/additional fan or cooling device for laptops that I could use to keep this from happening? I don't want this to happen when I am performing live.
