There is more than enough. I already use my tube for several Intel CPUs with heads.

However, I would advise against soiling the IHS and CPU cooler with it. The temperatures will hardly be better and the visual "damage" to the CPU is not worth it in my eyes.

The same applies to an air-cooled graphics card. Here you also have to reckon with a short circuit if you don't insulate the small units next to the chip with nail varnish or WLP.

I agree 100% with the previous speaker, unless you want to head an Intel CPU, I would advise you against this stuff:
1. it does almost nothing for an AMD CPU (I have a 3900x myself) because they are already soldered.
2. if you want to grease it between HS and CPU cooler I would also advise against it because you have to be careful what kind of cooler you use because it attacks e.g. aluminium, it is electrically conductive (normal WLP is usually insulating) and once you have mounted it under a suitable cooler it is almost impossible to get the cooler off later because it really sticks.
Rather buy the Thermal Grizzly Kryonaut (Extreme) WLP, use it yourself, it's really great (warm water bath beforehand, then it can be processed well).
