Best method for thermal paste

busu3

I have tried repasting with the pea, spread and x method. I dont know if I am doing something terribly wrong because my temps are still pretty high(CPU-80'c, GPU-74'C on max fans with kryonaut).
Currently I am using the x method.

Have you tried different thermal pads?
Ik they don't do much but uneven ones can make the pressure on the die uneven as well.

From what I read online, they dont recommend thermal pads for gpu and cpu, so i dont think they may work.

busu3   to me in my personal view the spread method its the best only a thin layer covering both diodes its enough too much paste its bad also if u have 80 on cpu and 74 on gpu while gaming those are pretty good temps but if youre going way over those while gaming im pretty sure its a bad repaste also changing the thermal pads wont do much they have nothing to do with the cpu/gpu temps they  re there mainly to mainly level the heatsink and provide just a bit of cooling to the vram chipsets (not much relevant) if they arent damaged no need to replace them and on the 2019/20  where there is a thick thermal paste over the vram chipsets dont use thermal pads it will most probably create temp issues normal thermal paste should be just fine or if possible apply a thicker one i have read the K5 pro its good for that good luck

Carbonaut or similar its not recommended for laptops (according to the reviews and tests) and even on desktops they dont provide the desired results so i wouldnt  advise them

Hi,
I prefer dot method and it worked well for me in the past, main thing you need to pay attention is tightening the heatsink screws, you shouldn't overtighten them, make sure that they are hand tight.

Fo the spread method how much paste do u apply in order to spread it? Last time I applied a very thin layer but I got really high temps so I want to know how much to apply. In case I want to replcae the thermal pads, what thickness should I use? Thanks.

For the dot method, how big of a dot do u apply and how do i ensure that the corners get covered too? Can u give a bit more indication of how tight hand tight should be? Thanks

This is how I repasted with very thin layer but this gave me 95'C. Pls point out any mistakes

You need to find the correct size by trial and error method, generally others quote a pea size or grain of rice size, when you start tightening the screw, you stop tightening further once it stops turning.

Ok so the correct size should cover the whole die when pressed down or its ok if it the corners don't covered?

Yes, let heatsink spread the thermal paste, then check the temperatures, if you are not satisfied, open again and check the die and apply slightly more paste or less paste, according how the heatsink spread the paste, you could also try different methods like cross method but don't put too much thermal paste.

I currently have the cross method only but i think i put too much paste. Also what size thermal pads should i use for vrams and other things?

Sorry, I don't know the size of the thermal pads, you have to wait for someone else reply about it.

Ok thanks a lot for the help

Its not explicitly mentioned but what is conveyed is to use 1.5 mm pads. So I think ill go with the 1.5 mm thermal pads. Is 6 W conductivity good?

Also should i paste the thermal pad on the chips or on heatsink?
