Up until yesterday, I had 8gb of RAM in my iMac; two 2gb sticks stock from Apple, and two 2gb cards that I added. With this current configuration, I would have an average temperature of 54 degrees, and never was really higher than 65 degrees. Last night, I removed all four sticks, and I went with four 4gb sticks. Ive noticed now with the 16gb of RAM, my temperature has been from 34-36 degrees. The iMac is faster on wake up as well. I never read anywhere that RAM cools a system down. Is that the case here? I noticed that I had the two stock Apple sticks on one side, and the two new ones on the other side prior to me upgrading to 16gb. Would that be an issue as well?
