When I'm browsing through firefox, the CPU temp goes from 51 to 55 degree celsious. the left side palmrest seems to be hotter than the right side palmrest. Is it me, or are these normal temps if browsing through firefox? HD Macintosh: 37 CPU: 54 CPU Heatsink: 45 Enclosure Base: 42 Enclosure Base 2: 42 Enclosure Base 3: 40 GPU: 46 Heatsink b: 44 Another thing I noticed is that whenever I watch a youtube video, the temp rises up to 60 degrees. I know that macs are not friendly with flash, but I was concerned if my new mbp is heating up more than it should. These results are from the istatpro widget.
