How many years does the thermal paste last in the tube ?

[Jarvis200q1]

I have bought a cooler master thermal compound and used it once so will the remaining thermal compound in the tube remain safe until the next use.

yeah it lasts really long just makes sure the tube is sealed well

Thank you

I've used thermal paste long past the expiry date and it still works great, I wouldn't worry about it unless it comes out of the tube with chunks in it.

ok

it depends on the make up, but generally they last until you run out.

If they 'cure' slightly  its usually while in use (heated)

 

but here's my gauge,   (if you can still apply it, like on day one its still fine)   they dont degrade unless you some how can leave it open to air and it can slowly dry out.

5 years if you have opened it. More if you haven't. Noctua guarantees 3 years in opened tube, but remember that thats only what they have tested.
