REEGOR  The 1.3 SMC update has an unclear effect on temperatures. (It brings me up to version 1.27f2 - go figure.) I was running up to 83C or slightly higher according to iStat, under moderate to heavy load. (The load was an external monitor streaming Netflix, Wi-Fi running at 150 KBps, and several applications. This does not seem like a heavy load to me, but I guess decoding a movie takes work.)

Tonight, I went up to 83 without even any streaming (but with an external monitor). But after a few minutes it has settled down to between 72 and 76.

Here's my complete temperature list for comparison. First number is first reading; second is 10 minutes after startup.

CPU A 82 / 71

Airport Card 51 /52

Battery 30 / 30

Enclosure Bottom 33 / 34

GPU Diode 82 / 79

GPU Heatsink 68 / 65

Heatsink A 62 /61

Heatsink B 46 /45

Memory Controller 52 /51

Hitachi Drive 21 /21  
(Version 1.3)

FELIX01  To reiterate, not for unibody MBPs.  
(Version 1.3)

YOXI  Not for late 2006 MBP's either.  
(Version 1.3)

SUCKERPUNCH86  Is this meant only for the unibody models?
