Manufacturer description

The 3.5g syringe covers roughly 3 to 20 applications depending on die size, from about 3 on a Threadripper TR4 heatspreader down to around 20 on an LGA1200 chip, so a single tube can outlast several builds. You don't need to pre-spread it before mounting the heatsink, which removes the fiddliest part of a cooler install, and the three included NA-CW1 cleaning wipes handle removal without hunting for isopropyl alcohol. Noctua rates NT-H2 for up to 3 years of storage and up to 5 years of use on the CPU, so you're not re-pasting every season. It works with air coolers and DIY or AiO liquid…

Noctua's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.
