Questions about this item

Should I pick the 20g or the 60g pack?

This offer provides 60g total, supplied as three 20g cans. That quantity covers roughly 60 to 120 applications, so the larger pack is practical for multiple laptops, consoles or graphics cards.

What does the K5 PRO rating mean once it is inside a laptop or console?

The compound is a viscous, non-conductive putty that replaces soft thermal pads up to 3mm thick. It stays pliable from -90 to 250 Celsius and fills gaps between memory chips and heatsinks without drying out.

How does the paste behave on a GPU such as an RTX 3080 or 3090?

It applies directly onto VRAM and GPU dies with the included wood spatula, conforms to uneven surfaces, and remains stable through repeated thermal cycles in high-end cards and consoles.
