I also had this heat issues with the i5 model. I removed the heat sink today and applied some liquid metal on the chip and temps drops up to 16C with some CineBench runs. Idle temps drops only by 7C.
Unfortunately, Apple is using low quality toothpaste on their chips. It seems like apply waaaaaaaay to much as well.
