Thermal Grease

Thermal Grease sound kinda weird to have huh? Well what do you all think of Thermal Grease does it do what I says it does and keeps things cool.
 
When you place a piece of metal (ie the heatsink) on another piece of metal (ie the CPU) there will be small pockets of air. Air has very poor thermal conductivity so this creates what is known as contact resistance. Adding thermal grease/paste fills some of these gaps and is fairly thermally conductive (a silver solution is often used). This acts to decrease the thermal resistance allowing heat to escape more easily.
 
basically this just makes the processor and the fan able to run at better speeds, because there is maximum conductivity between them.

The thermal grease never (and isnt supposed to) touch the fan so i fail to see how its going to "allow the fan to run at 'better' speeds" :)
 
Thermal compound applied in between the contact surface of the heatsink and CPU die surface effectively increases the overall thermal transfer efficiency (usually measured in watts). Lapping the surface of the heatsink further improves the efficiency, and using more “exotic” thermal compounds (such as Arctic Silver 3) futher increases the efficiency. Sure, just like everything in life there is a such thing as “the point of diminishing return”, but it’s always fun to see how far we can take things.
 
One more thing.....

It can actually lead to improved (slower) fan speeds when applied because it will conduct heat better and the result will be a lower needed airflow. As a result, it can theoretically lead to better FAN performance. However, it's not really a choice of having or not having thermal grease. It's a matter of life and death for modern CPUs.

Well watts/m²·ºC

With modern systems, the mobo handles heat protection -- even water and vapor chilled computers can die -- its not the heat that kills them -- its the voltage :)
 
I read somewhere that grease was for test benches(remove,install,remove,install)
Aren't thermal pads used

As far as I have seen thermal pads only come with stock heat sinks. Thermal paste is needed for most aftermarket HSFs.

Test benches... all the more reason to use the paste rather than the pad (cuz when testing you tend to push the system harder than general use)
