Has anyone replaced the HD Cooling Fan in their 27" Intel iMac? This in reference to an iMac (27-inch Late 2009, 2.66GHz Quad Core i5) ending in serial number in 5PJ.I recently replaced the HDD thinking it was making a lot of noise. I used the proper cable, so my HDD Fan Speeds are all working fine.However, it turns out that the HDD Cooling Fan is what is actually making the noise, even at it's slowest (1100 RPM) speed.
