I am having this issue when I am using PS CC and my Wacom Tablet.
Every time that I begin to use the lasso tool tracing around and image with my Intuos Wacom table the fan on my Retina Macbook Pro 13' the run about 4900 RPM and every time I switch a tool the fan then goes back to their normal RPM.
Has anyone heard of this issues and if so what is the Fix.
