Hey all, I did a quick search (google and MacRumors) about this but did not really come up with anything. I just replaced my failing hard drive in my late 2011 15" 2.2 MacBook Pro with a Samsung 840 256gb. Before I put in the SSD I was getting temps of around 100 deg. F or so. Now with the SSD in there the temp readings (from iStat pro) are anywhere between 120-165 deg. F. Fans are not acting up or anything. They seem to be at normal speeds. Currently I'm at 153deg. F and fans are just a click under 3k RPM Whats up with that? But everything else is great. The SSD was a HUGE improvement!
