Hi,
I have iMac 2008 with ODD fan problem. Immediately after I turn iMac on, ODD fan starts blowing at full speed. I have original configuration no SSD, no mods etc. Also try to reset SMC and clean dust but it did not solve the problem. SSD fan control shows normal temp for ODD sensor, also try to manual correct fan speed whit software but fan is not responding, always blows at full rpm,..
