How to measure IC7 thermal paste

[Netorious]

Hi,
I am little bit confused to work with the thermal paste. I got this from a friend but he is not currently here to help, I am getting such issue to measure the IC7 on that...please would you all have any guidance on such issue because I am currently running on that...

Thanks

Thermal paste is a maximum heat conductive paste which is used between two objects (commonly a heatsink and a CPU/GPU) to find actual and good heat conduction. It fills in all those microscopic imperfections on the heatsink and CPU/GPU which can trap air in them and cause a loss in the heatsink's performance. Air is a very bad conductor of heat. Thermal Interface Materials (TIM) can be up to a 100 times much good conductor of heat than the air. However, thermal paste is not so close as better of a conductor as copper. Thus, so many thermal paste will hinder a heatsink's capability to cool completely.

If you could have a completely flat heatsink base and CPU, you would not require thermal paste. But it is impossible to perform as so, and that's why you have to require and go for the thermal paste.There are commonly three kinds of thermal pastes:

• Metal based
• Ceramic based
• Silicon based

There are one more also that needs to get listed in order to this named as thermal epoxies, these are commonly the same thing as regular grease, but are actually being used to permanently attach the heatsink. They are not suggested to use for most scenario, but in some they are of course. One primary example for a use of an epoxy is, attaching heatsinks to video memory. Probably, you use thermal pads that don't act very fine, so an alternative is thermal epoxy. But the bugs is, commonly, you will not get the heatsinks off once they are placed on.

What can be tried to find epoxied heatsinks off is to place the video card in the freezer before trying to pull out the heatsink. The minimum and you can say bad temperature will make the epoxy brittle, so it goes off simpler.

When selecting a paste for your heatsink, you have two primary kind of components that are commonly considered; metal-based or ceramic-based.Probably, The user use the metal-based, easily because it acts good as stated before. But in these days, especially with GPUs, there are a number of transistors/electrical components that are very near to the die.

So when going to use thermal paste, if you are not very familiar with implementing it, there is a chance that when you move the heatsink, some of the paste can be squeezed out onto theses transistors/electrical materials and cause a short. This is no good of course and is a nightmare for anyone.

If you are going to install a latest heatsink before you even had a heatsink on you CPU, then there is no requirement to perform this. But in the case of placing a new one onto them, or changing a video card cooler, then you must clean your chip primarily.

To accomplish this, most used is Is properly Alcohol, Acetone, or a solution called ArctiClean. For working with the cleaners, use non-linty cloth or Q-Tips (cotton swabs). Q-Tips are much better where they are simple and easy to get where you need, plus you can also see properly what you are going to do.

Using thermal paste is a easy task, but you must consume your time as with entire things. One thing should be considered that what the thermal paste is actually perform. It provides much good conduction between the heatsink and CPU/GPU because it fills in all those small imperfections on the heatsink that cause bad conduction due to containing air in them. You only require as much thermal paste as it consume to fill in these small holes/divots.

Some users will "lap", their heatsink so they find it smoother. It will increase performance even much than that. The more area that the heatsink has reaching at the CPU/GPU, the good thing is that it will do. When you lap your heatsink, and you perform a good task of it, you will need even less thermal pastes, as these imperfections have found even smaller.
