Hi Folks
Surprisingly, all the replies to my previous detailed Email
(i.e. www.mail-archive.com/[EMAIL PROTECTED]/msg19147.html)
have not addressed my main query (which I repost here in abbreviated form).
My PowerBook Firewire G3/400Mhz had to have the 400Mhz processor module
(661-2386, P3589) replaced (I COULD TRACE DOWN THE FORMER NUMBER; BUT WHAT
DOES THE NUMBER P3589 MEAN?) to solve its booting/sleeping problems
(i.e. www.mail-archive.com/[EMAIL PROTECTED]/msg18290.html)
Previously, temperature monitoring (using the TAU on the PowerPC 750) indicated
a temperature of around 30-40 Celsius. However, with the new CPU installed,
I am getting CPU TAU readings of 90-114 Celsius (The internal IBM 40GB GN
Travelstar disk with SMART monitoring has temperatures of 25-45 Celsius).
The original processor in the Pismo was maybe a previous generation
(DO THE NUMBERS IN PARENTHESES INDICATE GENERATION?) with the designation
PowerPC 750 (83.0) 400Mhz while the currentnprocessor has
an updated numbering: PowerPC 750 (83.2) 400Mhz. COMMENTS?
I believe that the Pismo uses IBM PowerPC parts (since the Motorola equivalent
is called an MPC750) so perhaps:
1) what I am seeing is an inaccurate uncalibrated number for the CPU temperature
and it is indeed running at a much lower temperature (e.g. 40 Celsius).
2) However the link www.xlr8yourmac.com/tips/G3_temp.html mentions that
it is possible to install the heatsink on the chip with poor thermal conductivity.
So it could be that the CPU is running hot due to poor installation.
IS THIS REASONABLE? SHOULD I GET THE APPLECENTRE TO REINSTALL WITH THERMAL PASTE?
I am thinking of checking with the AppleCentre where I hope I can speak to the
technician who did the reinstall. Or should I just happily use the laptop till
it fries. Externally the Pismo doesn't feel much hotter than normal (the base
of the unit is always the warmest part).
QUERY: Could all those folks with PowerPC 750 chips (400/500 Mhz) in their
laptop use a Temperature monitor (Thermoindock, Temperature monitor) to give
me a ball park idea of how much these readings can vary?
Thanks, Harry.
