guys,
wanna ask your all bout arctic silver 5. ya..ya..i know MX-2 is currently the best, but i still have plenty of AS5 lying around and according to goldfries, MX-2 only differs buy 1 degree.

anyway, my question is, do I need to keep applying fresh AS5 after a period of time to maintain optimum performance?

I read that some of you guys have problem with hardened AS5 after a while. does this happen to MX-2 also? cause i'm just plain lazy to change new coat of TIM every now and then. if MX-2 can perform/last longer, i might consider ditching my AS5.

It's not too bad if you want to take the risk of shorting out something you're comparing something that isn't conductive to something that's conductive Ceramique is stupidly cheap compared to MX-2, at that price it's a pretty good buy for people who are always swapping processors in and out

Not Electrically Conductive. Arctic Silver 5 was formulated to conduct heat, not electricity.
(While much safer than electrically conductive silver and copper greases, Arctic Silver 5 should be kept away from electrical traces, pins, and leads. While it is not electrically conductive, the compound is very slightly capacitive and could potentially cause problems if it bridges two close-proximity electrical paths.)
