correct way to use thermal paste

post #1 of 13
Thread Starter 
This might have been posted, and I googled it but cant seem to find a definitive answer. Can someone please maybe draw a small picture with MS paint or something to show just which way and how much thermal paste should be applied to a CPU? I know that using too much or too little can negatively affect the heat dissapation, but I cant figure how much is ideal.

Thanks guys!

There is no actual correct way to apply it. Maybe this will help: in theory what you want to do is get enough paste to cover the cpu but no more than that. What you could do is put a dot on your cpu and use something to spread it like a latex glove on your finger or a plastic bag. Also what a lot of people do is put a dot on the middle of the cpu and use the heatsink to spread it.

Everyone does it differently, but this is my method:

1. Put a small amount in the middle of the CPU, about the size of a pea (You might have to try a few times to find the correct amount to cover the cores, but you only need a paper thin layer!)

2. Have the heatsink ready to go and push it down on the CPU/GPU/Chipset and then wiggle it slowly a few degrees to the left and right to help squeeze out any air bubbles.

3. Tighten your screws and away you go!

I'm sure alot of people would disagree, but i became so sick of using a credit card to spread it, i just think that method works just as well and it much faster.

Also if you watch a lot of overclocking videos from those extreme overclockers they usually just do the drop methos as well.

Basically this. No need to make applying TIM difficult. Just put a small drop about the size of a grain of rice, put on heatsink, wiggle it, and install!

Ahh cool. Its easier than I thought. I remember reading the AS5 official manual online somewhere and it wanted a strip across the cores on my old Q6600.

Thanks guys!

No Offense intended to the OP in this at all. But it is not really that difficult to find various methods in applying TIM. YouTube has more than enough videos on how to do it for more than one type of heatsink. No to mention that if you use the Search area here on the site and search for TIM Application you will find all the info you need. I underatnd that you are new to the forums so we won't rip you a new one. Best bet is to use the Search Area you see near the upper right and see what posts are already available for the info you are looking for

Good Luck in your future endeavors and welcome to OCN!!

I actually don't recommend the pea method or spreading. The pea method without spreading causes a circular spread, which the CPU obviously isn't round. Spreading causes air pockets after the heatsink is screwed down, which leads to heat being transferred less efficiently.

You want to allow the heatsink to do the spreading. The two line method is the best by far in my book. Split the CPU into thirds in your mind. Now put a line about half the length of the CPU on each third line. You'll have to get a feel for how thick the TIM lines need to be, but they don't have to be very thick. Now, when you apply the heatsink, let it wiggle as little as you can manage. Excess wiggling or pulling upward can also introduce air. Tighten each side a turn or two at a time, making sure the pressure stays relatively even as the TIM spreads.

It sounds complicated, but it really isn't. What you're ultimately shooting for is any imperfections between the CPU and heatsink being filled with as little TIM as possible and with as much metal to metal contact as possible. Metal transfers heat better than TIM.
