CPU fan speed running at full speed
I have iMac 21,5'' from 2011 with SSD Drive and i have problem since yesterday.
After boot (10 minutes, 15 minutes, sometimes only need to 1-2 minutes) CPU FAN turns on full RPM.
I checked temperatures in Macs Fan Control and they're all ok.
I did NVRAM and SMC reset, and nothing.
I have SSD drive, but i bought him without HDD.
Can you help me? I don't know what can i do.
I opened it but I do not see anything suspicious inside.
With CPU FAN 100%, iMac frees 50% :(
Since i opened it, fan rpm is in the norm.
Is this a good question?
