How many tubes of thermal paste do I need

post #1 of 8
Thread Starter 
Right now i have one tube of thermal paste. Would that be enough to cover a gpu and cpu? Or should I pick up another tube. Thanks

One tube should be enough. Rice grain method, man. I use it on all my chips, CPU or GPU. Works great.

if your using more then a pea sized dot on your chips, your using to much, and your temps are going to suffer.

No you don't need another tube. One will last several applications as you only need a grain of rice size bead each. Putting a lot of it would have the opposite affect of insulating it which causes temps to rise.

One tube ( depending on size ) should last you quite a few applications. My typical AS5 will last me maybe 20? applications or more, just as a rough guesstimate. Some larger tubes like the Noctua NT-H1 will last even longer.

Like the others said, simple pea or rice grain method works the best. If you put too much on it'll actually be worse.

Alright Thanks

I agree with everyone else here. One tube is plenty and don't overdo it! The function of the paste is to provide an interface which transfers heat from the chip to the heatsink. Too much and it acts as an insulator. Too little and there is air between the two - a poor conductor of heat by comparison.

A single tube can usually do between 5-10 applications on a CPU. Depending on the die size of a GPU, you can get about 3-5 applications from a single tube.

With MX-4, I can usually get about 5 applications for my CPU and my GPU is about the same as well. Then again I got 15 tubes sitting and ready when I need them biggrin.gif


As far as how much you need, you only need about a glob the size of a pea in the dead center of the CPU. No need to spread it as the heat sink will do that for you.

For GPUs, I generally do a big glob in the dead center if the die is square. If it is retangular, I do a thick line length wise.
