Is 1 g of thermal paste enough?

[Carlosdjg]

Hello. I have decided to re-paste my laptop using Thermal Grizzly Kryonaut and I'm looking to buy the 1 g tube but, is it enough? Or should I go for the 5.5 g tube? Thank you :)

1g is enough for most single users. 5.5 is for people that work on pcs for a living.

Thanks, I will buy the 1 g tube. Also that was an extremely fast answer haha.

Just remember...very thin layer...you are not gluing the components.

1g is enough, Kyronaut is a bit expensive, an alternative is MX-4 or AS5.

Not a layer, you don't want to spread it yourself, put a pea sized amount.

true, bad choice of words, but you get the picture

Since you are doing a laptop buy more, you want the entire chip die to be covered. You will use more paste on a laptop then on a desktop PC.

No you wouldn't unless it's needed to be done multiple times over years.
Laptop die for both the cpu and dedicated gpu combined is smaller then a US 10 cent coin

Yes it's small, but you will use 3x the amount of paste on it to make sure the entire die is covered. These things don't have heatspreaders, if you only cover half of it the chip will throttle and it could die over time.

I haven't needed to use more than a large pea sized amount on my laptop to completely fill the die, it's not as drastic as 3x but yeah you do need a bit more.

You shouldn't use the pea method. Use the cover core in a thin layer method when it's a laptop.

Buy the 5.5 gram tube, save the extra for later down the road.

I forgot today's stuff has larger cores.

Heres an example...

I use line, what's the cover core method?

[Bad 💀 Motha]

Bro... spread it out so the whole core is covered in a thin layer. Plus this way the force of the heat pipe cooler doesn't push the paste way out past where you really want it.

[Omega]

I just use the line and cross methods and spread a generous amount of paste. I use line on the rectangle shaped chips and cross on the square ones. I usually use stuff like MX-4 which spreads really well, the mounting pressure of the cooler will make sure the paste spreads everywhere.

No harm in using much paste. Any excess will be pushed away by the mounting pressure.

In the end, as long as it's non conductive paste and also not super thin like liquid metal and it works to keep the cpu and gpu below 90-95 area at all times should be fine. If in a short period after new paste if your temps start climbing too high it will then usually be due to dust build up or the fan dying.
