Just Installed a OEM stock Apple Dual 500 G4 card in my Sawtooth.

This would be equivalent to a dual 500 or dual 450 from Apple STOCK

I am a bit worried

Processor heat is clocked at 36 on one and 44 on the other at "nothing running"

Please send me your heat readings. I may need to reseat my heat sink or use some of that heat paste.

Dual 1.42 MDD shows 50 C

That sounds cool to me. Perhaps it's apples and oranges, but my 1.33 12" PowerBook was maxed out for hours yesterday -- the CPU was pegged at 100% set on 'highest performance' -- the temp was 60.5° and the fan was going mad. I turned CPU performance to 'reduced' after a while and the temp went to about 50°. Right now it is running only Firefox and it's 44.3° @ 14% CPU -- about as low as it gets.

iPulse is groovy for keeping track of it all....

Sounds okay to me as long as you have the original heat sink.

Thanks for the replies guys.

took a plunge...

Removed OEM heatsink, removed black (aluminium) contact pads from heatsink.

Applied liberal amount of heat paste, grey or silver kind. Reinstalled.

now reading 24 and 32 at idle

Dont know why there is almost a 10 degree difference between 2 processors but ok. its not running at 60 degrees either.

Thanks all

Ya I don't think you re gonna see both cpus at the same temp.

I have a dual 450. Thermo InDock gives me an average reading of 28 & 36 sometimes 32 & 40

As a really useless side note, at work it's not uncommon for me to see PPC750's and 74xx's running with junction temperatures at 90-ish C... But I don't think those chips are the ordinary commercial-grade parts that go into our Macs.

Temperature Monitor says that my Mac (Sawtooth, single 500MHz) doesn't have any sensors. Maybe it's only on the dual processors?
