"...but why not use the 12V from the fan connector?"
Because I was not sure if having the motherboards fan pin open would cause a hardware error. If it did then I would need to keep the fan connected, and tap into the bluray drive for power (because it's in a easier to access location). But now that I know it does not I can just make a 3 pin to molex adapter (using your diagram and leaving out the PWM control) to power the monitor. Then the fan control function can ramp the fan speed automatically based on the alarm setting I choose, and not the Sony default values. Should be as good or better than Killerbugs hidden fan control mod. No need to cut anything, plug and play, the ability to set an alarm so you know when to take a break, and an external display of the temperature that is hidden under the translucent top cover, SICK! Thanks for the info.

The Cell and RSX bonding techniques are optimized to reduce thermal stress on these components, and thoes temperatures are only intended to be achieved once in its standard lifetime (from manufacturing to the first YLOD). Seeing as 85C is much lower than the melting point of the tin solder used to bond it to the motherboaed, I would say it's in the ballpark, but 85C is way higher than say a conputer CPU's thermal max. It makes me uncomfortable setting the alarm at 75C. Especially when all I have to go on is an arbitraray mention in some online forum. Maybe I'll set it to the highest temperature achieved during 1 hour of online COD:MW2 (with new Artic Cooling MX-4 applied, allowing it a few hours to spread out and burn in, which it says is not necessary, but I may as well do anyway). That should give me a reasonably safe high temp don't you gus think?
