Today i was watching quite a lot of series on my iMac at full brightness and i turned the brightness down to around minimum and noticed a clicking noise i pretty sure its my fan. So i turned brightness back up towards maximum around mid way sound disappeared so lowered again and reappeared, so as stop watching videos and iMac cooling down the clicking noise started to ease.
I recorded the sound on my iphone and uploaded it, will some one have a hear of it see anything to be worried about. You hear it around 15 secs i think you probably notice a hight pitch sound also now and then thats the brightness issue because i am adjusting brightness so can tell the difference.
