Hi guys, I nee your help once again. I bought an Imac 2011 i5 off ebay in a good deal but i am having one minor hiccup: The HDD was replaced and the hdd fan is spinning a lot, in fact my perception is that they all are. I can hear the fans from the other room. I installed several fan control apps (smc / fan control) and they tell me that the fans are at 1200rpm which seems reasonable but that info is not compatible with the noise the imac is making. Now i am going to swap the hdd for an ssd so i will be opening it anyway. Could i remove the hdd fan altogether? Many thanks It is possible that something else is triggering the cpu fan?
