But noisy fans are a sign of a few things. One is that they are wearing out. I figure 2 years on fans in many cases so is this fan 5 years old?
I recently upgraded my HD on my Imac 17' bought in 2007 with a Hitachi 500 GB drive. I did it myself and since then the fan is making much more noise. I did the SMC reset to no avail. Using SMCFanControl, I checked the fan speed and I get these readings:
Do I need to look inside again, at the CPU to remove some dust. I am not sure what to do next.
Can anybody help me on that one ?
