I've had my new macbook for about a week now. I've noticed that for normal use, it is struggling to keep itself at what I would consider a reasonable temperature. I've scrounged around to make sure that I don't have any gremlin processes sucking up CPU cycles, but under normal web browsing, the bottom case temp sensors register in the range of 33 to 35 Celsius. CPU temp around 70 Celsius. The fan generally stays around 2000rpm, but will occasionally pop up into the 4000rpm~4500rpm range for a little while. Is this abnormal? The bottom of the case is nearing hot to the touch, even on a nice level surface.
