Question Arctic MX-4's shelf life ?

[knowledge2121]

I bought one of these in September 2021. And have kept it sealed since then..

This is the 2019 version ? Is there a newer version ?

Arctic says that the mx4 lasts for 8 years..is this the shelf life or how long the paste lasts once applied ?

Should i buy a new tube ?

You dont have to worry unless the paste is hardened or becoming oily.
