So ya, just like in the title I have a package of Gelid GC-Extreme unused still sealed in it's package that I bought 2 1/2 years ago and I'm wondering if it's ok to use right now. I am in the process of slapping together a quick build and plan to proceed with installation and if someone catches me in time to say don't use it I will go buy something else. If it's too late then I will still go buy something else but just hoping to get a quick helpful response. Thanks
