I bought Apple Cinema Display and a MBP Unibody. I was told that the lid of the MBP must be closed from boot-up so that the display will be transferred to ACD. I did this, I found out that after a while, even with no high cpu load or usage... it become very hot and fan goes up. The heat goes away when I open the lid... I tried putting a cooler fan below the MBP, didn't help. Any idea?
