I own a Mac Pro 2009 Quad, and every time I wake it up the fans spin and are VERY loud for about 2 to 3 seconds. I thought this was normal, but then I started a job where we use the same exact model of 2009 Quad Mac Pros. The Mac Pros at my work do not do this, and their fans are completely silent when they are woken up. Is this normal for my Mac? Is there any way to fix it? I have already tried resetting the SMC, but it still does it.
