Hello! Just like the title says, does this stuff expire? I just found some while I was searching and I forgot that I had it. I now remember it's probably about a year to a year and a half or so old.It's a little less than half a tube left and I want to replace my HSF unit with one with a copper-base. Can I still use what's left over or should I buy another new tube?

Provided the tube has been sealed properly, it should still be good to use.

Regards Howard :)

Thanks, man! It still has the cap on it.

If it comes out, and feels about the same as it did half a year before, I don't see why you can't use it :P

Also, remember that AS5 (and most other thermal compounds) should be reapplied every 3-5 years. I can't remember where I got that advice, but I'm sticking to it anyway. :D

Every 3-5 years, gotcha! Thanks!

by 5 years your PC is pretty much obsolete anyway!

I've used computers past 7 years before.... Besides, they make good file servers/firewalls/etc. If you wanna dump a northwood (or AMD equivalent), feel free to dump them this way.
