How safe is it to open my Macbook Pro myself to check my fans
Okay the fans are making loud nose and I wanna check if I can solve it myself by cleaning the dust and something else before taking it to get it repaired by Apple. How safe is it? Is it hard? Is there any chance I will wreck it? I'll be just opening it to clean the cooling fans.
MacBook Pro, Mac OS X (10.7.2), 2009 17 inches
