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. I’ve looked through the Take Apart Guides, but none of them go deep enough into the Mac to replace the HDD Cooling Fan. I have purchased the new fan, but I’m wondering how hard the install will be (I’ve done all sorts of teardowns, including very compact machines like laptops, but I have always had the benefit of a Tear Down Guide to help walk me through it). Any guidance? Is there an available Tear Down Guide that will get me most of the way there? Thanks.
I looked up the part and it only has three screws and an electrical connection. If I had to do this I would use the guide for replacing the hard drive and after I got the drive, out the fan may be easy to remove. Please take photos when you do it and upload them. If 90% of a journey is mapped out you should be able to do the last 10% on your own without to much effort. This is the first I’ve heard of on a fan failure on this machine. Have you confirmed this with AHT on your system installation disk?
I need to do it now, but am intimidated by disassembling computer to access fan. Adding ram was far easier.
