Well, ..Its time to go back to school.
Read a little physics and chemistry and you'll know why I mentioned all this about changing out the cooling paste.
I'm only 18 years old and I'm been proving every old engineer at school, work and private that our generation knows allot more than them in modern computers. Its not just a bunch of wires and cards sticking out here and there.
Computers ain't the same as in the 80's and 90's anymore, there's allot more going on in todays and our future computer's.

No, no it doesn't. I've got a computer science degree.

And I'm in *your* generation. Sadly.

Cooling paste gone? Dude. If that happened your computer would be on fire. Literally.

I'd either develop some humility or learn your stuff.
 
Zen and the art of Macocycle maintenance.

Well its not just fluff from cigarettes blocking the heatsinks in long term...

Think of what we humans have on us. Skin, our skin drops to the floor every hour in tiny bits. Mixing with the fabric from your clothes and furnitures.
Particles from cars exhaust and engine.
Salt from your sweat and tears.
Particles from hair products and cleaning products.

Tobacco smoke forms an extremely sticky patina which glues all our airborne excretions to surfaces and pets are some of the worst offenders for large amounts of fibers loose in the air. Hence my points about both items. I have seen the inside of towers that smokers have owned long term the results are disgusting.
I am aware of human detritus but you seem to have completely missed the point that the temperatures have not changed significantly in 4 years. My Mac Pro has run that hot since day one.
Interesting enough I have a Macbook Pro that runs WoW with its i5 CPU (no discrete GPU) at 95ºc while sucking air through its keyboard like an Oreck. It doesn't seem to give a toss tbh..... :eek:
I have an iMac G5 which bounces its CPU monitor off 85ºc whenever stressed and the fans sound like a remote controlled aircraft flying round the room. 7 years later it still chugs away like a good un.
If the MP does start getting hotter I will do some remedial maintenance. Until then it ain't broken so I'm not fixing it.
Taking expensive and delicate components apart with limited experience and knowledge is far more dangerous than monitoring and maintaining airways.
I have a pet PC engineer available to do any thermal past application and strip/rebuild work when the time comes. :)

Riiiiggghhhttt!!!! Show some shred of proof. What makes you think thermal paste needs replacement every year? Show evidence.

You can make the experiment on your own fairly easy.
Spread some cooling paste on a piece of paper, take the time and see how long it take it to dry out.
Simple math and u know why.
Also compare the different brand of cooling paste which OEM companies using and various custom cooling pastes.

Do the same with a heatsink and heatspreader.
Remove the heatsink after a year of testing and scrape of the paste.
You will now see that the surface of the copper or aluminum is slighter darker.
Because there is pollutions on the surface. Use some alcohol or polishing product to see the difference.
Also compare different heatsink with cheap OEM cooling paste and custom cooling paste.

Because of the copper or aluminum which is usually used in heatsink products these materials release different particles.
Also the cooling compound breathes because of the temperature rices it makes the compound to somehow not boil but the molecules move around and attract particles in the air to mix in with the cooling paste and get stuck in there.

But mac pro's does not only uses cooling paste. The 3.0 GHz using a thin silver gasket. Over the years of heating up and cooling down this little piece just burst and cracks..leaving big pieces of the cpu heatspreader naked ...

no..modern computers since mid 90's is standard equipped with several automatic fuses or mcu's.
There is some of them in the PSU if theres any power failure and temperature failure.
The motherboard has some of them in case of shorted circuit, others for high temperature and others are used for various tasks to prevent a fire or any damage to your hardware or external equipment.

Specific on the Mac pro, several small red lights turns on to tell what error code is currently showing behind the the memory risers because of the Mac pro using an full sized Intel BTX server motherboard made at the FOXCONN factory in china assembled in Ireland before shipping the hole unit.

I've had the same thermal cooling compound on my computer for the last three years. By your logic, my computer should not be running. But yet it is. I have a 10 year old G4 Cube, same thermal compound, it is not automatically getting shut off.

Entirely incorrect, and this shouldn't be an automatic shut off situation. The CPU would heat and instantly fuse to the heat sink.

Thermal compound does not just up and float away. It's heavier than air, but that part should have been obvious.... Even if oxygen picked up the molecules (which is a whole lot of bunk right there), they wouldn't be able to "float away." There will be discoloration due to the heat, but the thermal compound doesn't burn off.

This is basic college level chemistry.

Take the time to see how long until it dries out? Uhhh. Thermal compound is supposed to dry out.

Thermal compound is for heat transfer, not cooling itself. It doesn't matter at all if it's wet or dry, or what color it is. All it does is allow heat to pass to the heat sink without the heat sink touching the the CPU and fusing to it.

It doesn't even sound like you know how thermal compound is supposed to work.
