Processor without Thermal Paste

It will over heat and shut off. The older systems would just burn up and start a fire most likely. All systems have a thermal shut down temperature now.

How about if I install the cooler without the thermal paste. I think the copper of heatsink should contact directly onto cpu.

Without TIM (paste), it will overheat. That is simple. If you attach the copper HSF to the CPU directly it will overheat, but you may save it from a complete fire, or burnout.

If you've ever worked on some OEM machines and have taken the heatsink off, you'll notice it has a very thin layer of a thermal pad that doesn't even seem to exist over the CPU. That's why those machines run crazy hot and sometimes shutdown. Thermal paste IS NECESSARY for a CPU to run optimally.

Its essential to effective heat management. Without it the heat sink on the cooler will not make correct contact with the entire cpu heat sink forming hot spots and compromising cooling.
Most likely the machine will just shutdown

I fried an old Athlon XP once by [actually] not seating the heatsink on properly. I smelled burning plastic and took the heatsink off to find a small black spot on the CPU.

Air is not a good thermal conductor.
Even though you may think there is little to no air between the heat sink and cpu you would be wrong.

Ask yourself this: If there was no need why would they use the compound to begin with.

Even the compound breaks down over time.
You will find several threads where replacing the compound or the thermal pad fixed the over heating issue.

I pulled apart my friends DV6000 and saw there was little to no thermal paste on it. Added some AS5 and the fan hardly runs now.

While the heatspreaders on the CPU and heatsink look smooth, they are far from it, so proper contact can't be made.

Not only is it necessary, at 5-10 bucks for a tube of AS5 or similar...its a miniscule cost to prevent a massive problem.

Heat sink cream is a small cost ($1 and up) and a important part when building a computer. Its hard enough even with heat sink cream to keep the temps down,but without it,the computer will run alot higher shortening the life of parts and cause frenquent shutdowns and restarts until parts start to fail and die.

Don't use the processor without the thermal paste.
Cooler/heatskink only is NOT enough to cool the processor.Thermal paste is used to transfer the heat on the cooler/heatsink in order to cool the processor as much as possible.If there is no thermal paste then no or VERY LITTLE amount of heat will be transfered,but not EVEN CLOSE as it is supposed to.

So do NOT do that.Never ever.
