Does old thermal grease work as well as new?

post #1 of 5
Thread Starter 
I have a tube of AS5 that's probably about 3 years old, with plenty left. Is there a benefit to buying a fresh new tube, or is it still just as good as it ever was?

Squeeze a little out, if you can. If it has the consistency of toothpaste then it's probably ok. If not, buy new stuff.

it will work just fine, I have much older thermal grease( same as you AS5)

here's a little trick, leave the tube under the sun or blow some hot air on it using a hair dryer for a couple mins before application. That should make it just about perfect.

It probably would have separated over time, so you may need a way to mix it together. Other than that there are no other spoiling ingredients so it should cool just as well as a new tube.

I've never had a problem using old thermal grease. Just wipe off any that has been exposed to the air on the tip and you'll be good to go.
