I noticed lately that my MacBook Pro was running loud even if they laptop was only up for ten minutes or so. I downloaded a program to control the fan and noticed that my left fan is not working. I also has the iStat widget which states the left is at 0 RPM. Is this normal? The MBP is running Leopard and it has all the latest patches. I am not sure what to do. Is this hardware or software related? What are my options? If I needed to get this repaired, would this be expensive? The laptop is about 2 1/2 years old. I am not sure how long the fan has not been working. If anyone can offer suggestions on what I can try to do, I would appreciate it.
