would you use a tube of AS5 from 6 or 7 years ago? i put some on a paper plate and it looks normal i guess... should i just use the tube that came with a cpu cooler i just bought. would there be a difference?
If it's not dried out and was sealed the whole time I say go for it I'm using ac5 from 6 years ago and have had no problems yet and I've been using it for a while now.
