First, I know there are many threads on this, I've read them all! This is my first MacBook so I'm unfamiliar if these temps are normal, I appreciate any help. Right now all I have running is Safari and Yahoo Messenger: Istat temps: HD: 33 C CPU: 49 C Heatsink: 41 C Enclosure base: 34 C Enclosure base 2: 34 C Enclosure base 3: 33 C GPU: 46 C GPU Diode: 48 C Right fan: 2001 RPM left Fan: 1996 RPM Is there something wrong? Why would temp be 49 with only 2 really simple things running? If its idling, temp will go down to about 40-42. It feels HOT on the bottom, which I understand because of the casing material, but still seems too hot? If I'm on webcam or anything with video, temp goes up to 58-60 C in about 2 minutes. Why would it go up so fast? Should I return this laptop?
