What is thermal Paste and what does it do?

It is a paste which goes between your CPU and your HEATSINK. It allows the CPU to push the heat onto the Heatsink.. It sonnects the two peices together with surface area.

YES you need it.
 
Thermal paste or compound transfers heat from your cpu or main chipset to the appropiately named "heat sink" in order to keep the chip from reaching high temps where damage would end in component failure. A thin layer of Artic Silver or another good brand is applied to form a thin layer inbetween the cpu or chip and the heat sink for this purpose.
 
its mainly used to keep a bond from your cpu to your heatsink. Make sure you use some sort of straight edge and smooth out the compound so there are no air bubbles.

You also need a very small amount, about a grain of rice or a bit more, but not more than that.
 
is thermal paste already apllied on the heatsink fan from the Intel Retail E6400 box sets? because there is a layer of black stuff under the heatsink, i believe htat is thermal paste.


coreect me of i m wrong
 
That or a thermal pad which does the same thing. You can use the stock stuff but if you are having heat problems, then go ahead and get some AS5.
 
No, unless you want to use Artic Silver 5 instead of the normal generic paste/pad included with your processor.
 
another question is that in Praetor's Building 101 thread, it said that when you get the heatsink out, you use a card or a tool to peel off the black layer. What is he talking about?

If it's lined up correctly the CPU will fall into place (don't drop it though) and you can then push the lever back into position. If you will be using some sort compound now would be the time to put it on. Before you do however you will need to remove the black pad or whatever other stuff is already on the heatsink. To do this take a plastic tool (card or something else that won't bend or scratch the metal) and scrape off the pad. Wipe off the rest with a xylene based cleaner, acetone, or isopropyl alcohol. Putting on the heatsink is fairly easy also, lay the heatsink on top of the CPU (Don't push it on the clips will do that for you) and very carefully push the clips into the correct mounting spot. After they've been "clipped in" push down on the 2 locking levers (they are in different spots for different heatsinks, just look around).
 
Those are thermal pads and generally they suck. Really what you should do everytime you remove a heat sink is wipe it down and clean it off with some isotropyl alcohal (its non conductive) and reapply a thin layer of thermal paste to make a bond to your heat sink.

Removing the pad is a fine idea.
 
That would be if you don't want to use the stock thermal pad. It is much better to use AC5 if you will be overclocking, though it is not a must.
 
yes you need thermal past it conducts the heat away from the cpu and to the heatsink ,if you are buying a cpu (retail) then it will come with the heatsink and it will have past on it already so you dont need to buy any ,
after a while if you
notice the cpu temp getting alot hotter it might be time to buy some thermal past and replace the the old past i recommend artic silver

Are you joking? It is always better using AS5 over the stock thermal pad even though those are replaceble after they start to get dried out and brittle to some degree. AS5 has far more silver dioxide along with a better ceramic bonding material. Once you decide on better cooling even for a stock machine you would need a good compound at least equivalent to AS5. On stock systems I don't even run stock HSFs any more. The idea behind having a better grade compound over stock is to protect your cpu at all times whether ocing or not.
